Quelles sont les extensions et bibliothèques PHP dont WP a besoin et / ou utilise?

J'ai réfléchi davantage à celaet étant donné lataille de labase de code WP (y compris lesbibliothèquesgroupées),ilne semblepastrès réaliste de compiler unetelle liste à lamain (et de la répéterpour chaquenouvelle version -meh).

J'ai recherché un outil d'analyse de code statique approprié - PHP_CompatInfo et après quelquesbricolages,généré suite au rapport desextensions utiliséespar lenoyau (version analysée 3.3.1):

• cURL - 127 utilisations (nécessite libcurl )

  • API HTTP (classe WP_Http_curl)
  • url_is_accessable_via_ssl()
  • SimplePie (remplacépar la classe WP_SimplePie_File)
  • GoogleSpell (dupackage TinyMCE,n'estpas utilisé?)

• Date/Heure - 367 utilisations

• DOM - 6 utilisations (nécessite libxml )

  • iis7_rewrite_rule_exists()
  • iis7_delete_rewrite_rule()
  • iis7_add_rewrite_rule()
  • saveDomDocument()

• POSIX Regex - 23 utilisations

• Filtre - 2 utilisations

  • classe PHPMailer->ValidateAddress() (facultatif)

• FTP - 72 utilisations

  • classe SimplePie (facultatif)
  • wp_check_invalid_utf8() (facultatif)
  • wp-mail.php (facultatif)

• JSON - 20 utilisations

  • facultatif,solutions de secours dans wp-includes/compat.php

• libxml - 4 utilisations

  • classe WP_oEmbed->_parse_xml() (facultatif)
  • SimplePie

• Chaînemulti-octets - 29 utilisations

  • une solution de secours dans wp-includes/compat.php

• MySQL - 60 utilisations

  • classe wpdb
  • class SimplePie_Cache (remplacépar la classe WP_Feed_Cache)

  • wp_doc_link_parse() (facultatif)

• Analyseur XML - 89 utilisations

• XMLReader - 1 utilisations

  • SimplePie (semblefacultatif)

I gave this some more thought and given size of WP code base (including bundled libraries) it doesn't seem very realistic to compile such list by hand (and repeat it for every new version - meh).

I looked up appropriate static code analysis tool - PHP_CompatInfo and after some tinkering generated following report of extensions used by core (version scanned 3.3.1):

• cURL - 127 uses (requires libcurl)

  • HTTP API (class WP_Http_curl)
  • url_is_accessable_via_ssl()
  • SimplePie (overridden with class WP_SimplePie_File)
  • GoogleSpell (from TinyMCE package, is not used?)

• Date/Time - 367 uses

• DOM - 6 uses (requires libxml)

  • iis7_rewrite_rule_exists()
  • iis7_delete_rewrite_rule()
  • iis7_add_rewrite_rule()
  • saveDomDocument()

• POSIX Regex - 23 uses

• Filter - 2 uses

  • class PHPMailer->ValidateAddress() (optional)

• FTP - 72 uses

  • class ftp_base
  • class ftp (pure and sockets versions)
  • class WP_Filesystem_FTPext
  • class WP_Filesystem_ftpsockets

• GD - 56 uses

  • wp-admin\includes\image-edit.php
  • wp-admin\includes\image.php
  • wp-includes\media.php

• Hash - 6 uses

  • wp-includes\pluggable.php multiple uses (optional - fallback in wp-includes\compat.php)

• iconv - 5 uses

  • class SimplePie (optional)
  • wp_check_invalid_utf8() (optional)
  • wp-mail.php (optional)

• JSON - 20 uses

  • optional, fallbacks in wp-includes/compat.php

• libxml - 4 uses

La réponse à cette questionpeut être compliquéeet très longue,pour autant queje sache,il y aura également des différencesentre les serveurs & amp; OS (IIS,Apache) .. Jene peuxpas dire que la liste suivanteest une liste COMPLÈTE,maiselleinclut certains de ceux queje connais qui sontnécessaires:

• Curlet CurlSSL - Jene suispas sûr que ce soit REQUIS mais unegrandepartie du code WordPress l'utilisera s'ilest disponible. Cependant,denombreuxplugins EN lenécessitent et/ou auront desfonctions limitées sans lui.

• Exif -permet augestionnairemultimédia de WordPress d'extraire des données Exif à court d'images.

• Gettext - .po .mogère l'internationalisation de la localisation destraductions.

• FTP - utilisépourfaire desmises àjour depluginset de WordPress via FTP.

• GD - Pasbesoin deprésentation,non?.

• Iconv - conversions dejeux de caractèrespourtout,du courrier à l'analyse RSS.

• Mbregexet Mbstring - lenomest assez descriptif -fournissent desfonctions utiliséespartout :-)

• Mcrypt - Nonnécessairepour wordpress,mais denombreuxpluginsen ontbesoin.

• Mime Magic - Désapprouvémaintenant dans wordpress -maistoujours utilepour la compatibilité.

• * MySQLet Mysql du système * -nous savonstous ce que c'estet pourquoi c'estnécessaire,non?

• Openssl - Cettebibliothèqueest utiliséepourgérer les connexions detraitement crypté avec des certificats SSLpour WordPresspeut êtreen mesure de se connecter àn'importe quelemplacement crypté SSL (https).

• POSIX - utilisépour s'assurer que WordPressmaintient correctement les autorisationset lapropriété desfichiers.

• Vérification desinformations de chemin - certaines configurations depermalien.

• Pspell - capacités de vérification orthographique de TinyMCE,.

• Sockets -gestion des connexions FTPet gestion du courrier AKA SMTPet POP dans WordPress.

• Zip - Jene saispas si REQUIS -mais cette classe de créationet d'extraction defichiers zip compatiblemultiplateforme SERA utiliséepar wordpress sielleest disponible.

• Zlib - Utilisé dans denombreux cas.exemple - compression defichiersjset css.encore unefois,je ne saispas si REQUIS maisnécessaire.

Commeindiqué ci-dessus -ilne s'agiten aucun cas d'une liste COMPLÈTE -elle a été compiléeil y aenviron un an -et peutnécessiter unemise àjour. Beaucoup de cesfonctionsne sontpasexactement REQUISES mais CONSEILLÉES . Dans denombreux cas,wordpress utilisera unefonction SIelleest disponible,et sinon,ignorera latâche. Unbonexempleest lemanque debibliothèque GD,celan'empêcherapas wordpress defonctionner,maisilne recadrerapas,ne redimensionnerapas oune modifierapas lesimagestéléchargées - laissant ainsi l'original (etgrisé l'option "taille" dans le "insertimage àpublier "fonction) ..

Enpassant,je dirais aussi que cette question obtiendraprobablement des réponsesplus correctes/mises àjour sur serverfault.com qu'ici ...

The answer for this might be complicated and very long, as far as I know, there will also be some differences between servers & OS (IIS, Apache).. I can not say that the following list is a FULL list, but it includes some of those I know that are required :

• Curl and CurlSSL – Not sure it is REQUIRED but but much of the WordPress code will use it if it is available. Many plugins however DO require it and/or will have limited functions without it.

• Exif – allows media handler of WordPress to pull Exif data out of images.

• Gettext - .po .mo handling translation localization internationalization ..

• FTP – used to do plugin and WordPress upgrades via FTP.

• GD – No need introduction, right ?.

• Iconv – character set conversions for everything from mail to RSS parsing.

• Mbregex and Mbstring – the name is pretty descriptive - provide functions used all over the place :-)

• Mcrypt – Not needed for wordpress, but many plugins do need it.

• Mime Magic – Deprecated now in wordpress - but still good to have for back compatibility.

• *Mysql and Mysql of the system *– we all know what this is and why it is needed, no ?

• Openssl – This library is used to handle processing connections encrypted with SSL certificates for WordPress may to be able to connect to any SSL (https) encrypted location.

• POSIX – used to ensure that WordPress properly maintains file permissions and ownerships .

• Path Info Check – some permalink setups .

• Pspell – spell checking capabilities to TinyMCE, .

• Sockets – managing FTP connections and mail handling AKA SMTP and POP in WordPress.

• Zip – Not sure if REQUIRED - but this cross-platform compatible zip file creation and extraction class WILL be used by wordpress if available.

• Zlib – Used in many cases . example - js and css files compression. again, not sure if REQUIRED but needed.

Like Above stated - this is by no means a FULL list - It was compiled about a year ago - and it might need some update . Many of those functions are not exactly REQUIRED but ADVISED. In many cases wordpress will use a function IF it is available, and if not , will ignore the task. A good example is the lack of GD library, it will not stop wordpress from functioning, but it will not crop, resize , or alter the uploaded images - thus leaving the original (and grey- out the "size" option in the "insert image to post" function)..

As a side note - I would also say that maybe this question will probably get more correct/updated answers on serverfault.com than here ...

( Cecin'estpas destiné à être une réponse. Juste quelquesinformations utiles. Si vouspensez que cesinformationsne sontpas utiles,faites-lemoi savoir,je vais simplement les supprimer.)

Jepense queparleren termes de packages seraitplusfacilepour les débutants,mais comme lespackages varient d'un système à l'autre,ilest difficile de les couvrirtous.

Commej'ai de l'expérience avec Debian (& amp; distributionsbasées sur Debian),j'aimeraispartager cesinformations spécifiques:

• php5-cli
• php5-dev
• php5-fpm
• php5-cgi
• php5-mysql
• php5-xmlrpc
• php5-curl
• php5-gd
• php-apc (non obligatoire,mais recommandé)
• php-poire
• php5-imap
• php5-mcrypt
• php5-pspell

Lespackages susmentionnésinstallenttoutes lesextensions/bibliothèques/modulesmentionnés dans les autres réponses; tous,sauf Mime Magic,quin'est plus requispar WordPress .

Un autrebonmoyen de vous assurer que votre serveurest 100% compatible avec WordPressest de vérifier avec quelspackages les sociétés d'hébergementgéré sontpréinstallées. Commeils ont des années d'expérience avec lesplaintes des clients concernant lesincompatibilités,ils saurontmieux.

Dans le cas d'Hostgator ,lesmodules PHP qu'ilspré-installentincluent (vousn'auraprobablementbesoin que de laplupart maispas detous):

Media Templefournit un phpinfo(); pour que vouspuissiez vérifier leur configuration. C'est également utile à desfins de comparaison.

The aforementioned packages install all the extensions/libraries/modules mentioned in the other answers; all, except Mime Magic, which is no longer required by WordPress.

Another good way to make sure your server is 100% compatible with WordPress is to check what packages the managed hosting companies come pre-installed with. As they have years of experience with customer complaints about incompatibilities, they'll know better.

In case of Hostgator, the PHP modules they pre-install include (you'll probably only need most but not all of them):

Media Temple provides a phpinfo(); file for you to check their config. It's useful for comparison purposes too.

Si vous souhaitez vérifierfacilement si votre serveur répond à cesexigences,ilexiste désormais une commande WP-CLIext. pour lefaire.

wp ext required affichetoutes lesextensions PHP nécessaires pourexécuter WordPress,tandis que wp ext recommended affiche lesextensions facultatives . wp ext checkest une combinaison des deux commandes.

Voici commentfonctionne wp ext required:

 $ wp ext required

+-----------+-----------+
Success: All required extensions are installed
 

If you want an easy way to verify if your server meets these requirements, there's now a handy WP-CLI ext command to do so.

wp ext required shows all PHP extensions necessary to run WordPress, while wp ext recommended shows optional ones. wp ext check is a combination of both commands.

These come in handy when you need a quick way to check the system requirements on a new server and/or if you want to further process this list programmatically.

Here's how wp ext required works:

$ wp ext required

Si vous utilisez Debian 7 (Debian Wheezy),vous devezinstaller PHP lui-mêmeet unpetit nombre d'extensions. Laplupart de ce qui a étémentionnépar @Rarstest déjàinclus dans l'une desinstallations PHP lesplus élémentaires de Debian.

<₹PHP

Vous avez quatre options dans Debian Wheezy: libapache2-mod-php5 , libapache2-mod-php5filter ,php5-cgi ,ou php5-fpm . Je choisisphp5-fpmmaistout dépend de lamanière dont vous voulez que votre serveur Webet PHPinteragissent.

Vous avez égalementbesoin de PHPpour utiliser MySQL. Vos options sont php5-mysql et php5-mysqlnd .php5-mysqlndestnatifet généralementplus rapide. Certainspourraient choisir une alternative comme MariaDB.

Bibliothèquegraphique Facultatif

Si vous souhaitez redimensionner vosimages,vouspouvezinstaller php5-gd ou < a href="https://packages.debian.org/wheezy/php5-imagick" rel="nofollow">php5-imagick .php5-imagick vous donnera unemeilleure qualitéet Wordpress l'utilisera s'ilest disponible. Si les deux sontinstallés,php5-imagick sera utilisé. Sini l'unni l'autren'estinstallé,lesimagesne serontpas redimensionnées (et Wordpressne seplaindrapas).

HTTP Facultatif

Si vousinstallez php5-curl ,il sera utilisémaisn'estpas obligatoirepourtout saufpeut-être demeilleuresperformances.

Rien d'autren'est requispar Wordpresset laplupart desextensions,bien que certainesextensionspuissent avoir d'autresexigences.

Voici la ligne d'installation debase complètepour donner à Wordpresstout ce dontil abesoinpour desperformances optimaleset rien de ce qu'iln'apas:

 apt-get install php5-fpm php5-mysqlnd php5-imagick php5-curl
 

If you're using Debian 7 (Debian Wheezy), you need to install PHP itself and a small number of extensions. Most of what was mentioned by @Rarst is already included with one of Debian's most basic PHP installs.

PHP

You have four options in Debian Wheezy: libapache2-mod-php5, libapache2-mod-php5filter, php5-cgi, or php5-fpm. I choose php5-fpm but it all depends on how you want your web server and PHP to interact.

MySQL

You also need PHP to use MySQL. Your options are php5-mysql and php5-mysqlnd. php5-mysqlnd is native and generally faster. Some might choose an alternative like MariaDB.

Graphics Library Optional

If you want your images resized, you may install either php5-gd or php5-imagick. php5-imagick will give you better quality and Wordpress will use it if it's available. If both are installed, php5-imagick will be used. If neither is installed, images will not be resized (and Wordpress won't complain).

HTTP Optional

If you install php5-curl, it will be used but is not required for anything except perhaps better performance.

Nothing else is required by Wordpress and most extensions, though some extensions may have other requirements.

Here is the complete basic install line to give Wordpress everything it needs for optimal performance and nothing it doesn't:

apt-get install php5-fpm php5-mysqlnd php5-imagick php5-curl

Le manuel WordPress répertorie désormais lesmodules PHP recommandés:

Le cœur de WordPress utilise desextensions PHP. Si l'extensionpréférée ilmanque WordPress devra soitfaireplus detravailpourfaire latâche lemodule aide ou,dans lepire des cas,supprimera Fonctionnalité. Par conséquent,lesextensions PHP listées ci-dessous sont recommandé.

• bcmath - Utilisépour améliorer lesperformances des calculsmathématiques.
• curl - Effectue des opérations de requête à distance.
• exif - Fonctionne avec lesmétadonnées stockées dans lesimages.
• filtre - Utilisépourfiltreren toute sécurité lesentrées utilisateur.
• fileinfo - Utilisépour détecter letype MIME destéléchargements defichiers
• mod_xml - Utilisépourgénérer du XML,commepour unplan de site XML. Notez quemod_xmlest unmodule Apache,pas uneextension PHP,maisest répertorié pour la sensibilisation.
• mysqli - Se connecte à MySQLpour lesinteractions avec labase de données.
• libsodium - Génère des octets aléatoires.
• openssl - Autorise les connexions SSL à d'autres hôtes.
• pcre - Augmente lesperformances de la correspondance demodèles dans les recherches de code.
• imagick - Fournit unemeilleure qualité d'imagepour lestéléchargementsmultimédias. Voir WP_Image_Editor arrive!pourplus de détails. Redimensionnement d'imageplusintelligent (pour imagespluspetites)et priseen charge des vignettes PDF,lorsque Ghost Scriptest également disponible.
• xml - Utilisépour l'analyse XML,parexemple àpartir d'un sitetiers.

Il répertorie également lesextensions PHP suivantes comme étantfacultatives:

• gd - Si Imagickn'estpasinstallé,labibliothèquegraphique GDest utilisée comme solution de secoursfonctionnellement limitéepour lamanipulation d'images.
• mcrypt - Génère des octets aléatoires lorsque libsodiumn'estpas disponible.
• xmlreader - Utilisépour l'analyse XML.
• zlib - Compressionet décompression Gzip.

The WordPress handbook now lists the recommended PHP modules:

WordPress core makes use of PHP extensions. If the preferred extension is missing WordPress will either have to do more work to do the task the module helps with or, in the worst case, will remove functionality. Therefore the PHP extensions listed below are recommended.

• bcmath – Used to improve the performance of math calculations.
• curl – Performs remote request operations.
• exif – Works with metadata stored in images.
• filter – Used for securely filtering user input.
• fileinfo – Used to detect mimetype of file uploads
• mod_xml – Used for generating XML, such as for an XML sitemap. Note that mod_xml is an Apache module, not a PHP extension, but is listed for awareness.
• mysqli – Connects to MySQL for database interactions.
• libsodium – Generates random bytes.
• openssl – Permits SSL-based connections to other hosts.
• pcre – Increases performance of pattern matching in code searches.
• imagick – Provides better image quality for media uploads. See WP_Image_Editor is incoming! for details. Smarter image resizing (for smaller images) and PDF thumbnail support, when Ghost Script is also available.
• xml – Used for XML parsing, such as from a third-party site.

It also lists the following PHP extensions as being optional:

• gd – If Imagick isn’t installed, the GD Graphics Library is used as a functionally limited fallback for image manipulation.
• mcrypt – Generates random bytes when libsodium isn’t available.
• xmlreader – Used for XML parsing.
• zlib – Gzip compression and decompression.

Il convient dementionner que depuis WordPress 5.2,ilexiste unefonctionnalitéintégrée qui rapporte lesmodulesmanquants.Trouvez-le dans Outils> État du site.

It's worth mentioning that since WordPress 5.2, there is a built in feature that reports on missing modules. Find it at Tools > Site Health.

vous avezbesoin desextensionsmysqli,pdoet gd.etparfois xml-rpc.

J'utilise WP avec l'extensionnativemysqlnd depuis unmomentmaintenant,c'estplutôt chouette.A des éléments de réflexionintégrés,donc si vous voulez voir ce qui sepasse avec labase de données dans cette requête spécifique,vouspouvez lefaire.

zipen tant qu'extensionn'estpasnécessaire,laplupart desprogrammes appellent l'exécutable zip du système.

you need the mysqli, pdo, and gd extensions. and sometimes xml-rpc.

I've been running WP with the mysqlnd native extension for a while now, it's pretty neat. Has reflection stuff built in, so if you want to see what's going on with the db in that specific request, you can do it.

zip as an extension is not needed, most programs call the system zip executable.

Officiellement, WordPress.org dit que seules lesextensions PHP suivantes sont requises àpartir de WP Core 5.3+et lors de l'utilisation de la version recommandée de PHP,quiest actuellement PHP 7.2:

 curl -- Performs remote request operations.
dom -- Used to validate Text Widget content and to automatically configuring IIS7+.
exif -- Works with metadata stored in images.
fileinfo -- Used to detect mimetype of file uploads.
hash -- Used for hashing, including passwords and update packages.
json -- Used for communications with other servers.
mbstring -- Used to properly handle UTF8 text.
mysqli -- Connects to MySQL for database interactions.
libsodium -- Validates Signatures and provides securely random bytes.
openssl -- Permits SSL-based connections to other hosts.
pcre -- Increases performance of pattern matching in code searches.
imagick -- Provides better image quality for media uploads. See WP_Image_Editor is incoming! for details. Smarter image resizing (for smaller images) and PDF thumbnail support, when Ghost Script is also available.
xml -- Used for XML parsing, such as from a third-party site.
zip -- Used for decompressing Plugins, Themes, and WordPress update packages.
 

...maisils recommandent également lesextensionsfacultatives suivantes:

 filter -- Used for securely filtering user input.
gd -- If Imagick isn’t installed, the GD Graphics Library is used as a functionally 
limited fallback for image manipulation.
iconv -- Used to convert between character sets.
mcrypt -- Generates random bytes when libsodium and /dev/urandom aren’t available.
simplexml -- Used for XML parsing.
xmlreader -- Used for XML parsing.
zlib -- Gzip compression and decompression.
 

Gardez cependant à l'esprit que certaines de cesextensions obligatoires (oufacultatives) sont déjà regroupées dans d'autrespackages PHP. Parexemple,domest souventinclus dans l'extension xml. Et d'autres comme fileinfo sontprobablement déjàinstallés dans le cadre d'unpaquet dit php-common si vous utilisez Ubuntu,etc.

Deplus,ilexiste quelques autresextensionstelles que bcmath quine sontpas officiellement requises ou recommandéespar WordPressmais qui sonttoujours utiliséespar denombreuxpluginspopulaires,comme Yoast SEO.

Officially, WordPress.org says that only the following PHP extensions are required as of WP Core 5.3+ and when using the recommended version of PHP, which is currently PHP 7.2:

curl -- Performs remote request operations.
dom -- Used to validate Text Widget content and to automatically configuring IIS7+.
exif -- Works with metadata stored in images.
fileinfo -- Used to detect mimetype of file uploads.
hash -- Used for hashing, including passwords and update packages.

libsodium -- Validates Signatures and provides securely random bytes.
openssl -- Permits SSL-based connections to other hosts.
pcre -- Increases performance of pattern matching in code searches.
imagick -- Provides better image quality for media uploads. See WP_Image_Editor is incoming! for details. Smarter image resizing (for smaller images) and PDF thumbnail support, when Ghost Script is also available.
xml -- Used for XML parsing, such as from a third-party site.
zip -- Used for decompressing Plugins, Themes, and WordPress update packages.

...but they also recommend the following optional extensions:

filter -- Used for securely filtering user input.
gd -- If Imagick isn’t installed, the GD Graphics Library is used as a functionally 
limited fallback for image manipulation.
iconv -- Used to convert between character sets.
mcrypt -- Generates random bytes when libsodium and /dev/urandom aren’t available.
simplexml -- Used for XML parsing.
xmlreader -- Used for XML parsing.
zlib -- Gzip compression and decompression.

Keep in mind, however, that some of these required (or optional) extensions are already bundled into other PHP packages. For example, dom is often included in the xml extension. And others like fileinfo are probably already installed as part of a so-called php-common package if you are using Ubuntu, etc.

In addition, there are a few other extensions such as bcmath that are not officially required or recommended by WordPress but are still used by many popular plugins, like Yoast SEO.
