Compatibility/ja

MediaWiki strives to maintain broad compatibility between versions, and with a range of current and legacy software. At the same time, the constantly-evolving codebase and features of the latest MediaWiki development mean that it is not possible to maintain compatibility with legacy software indefinitely.

PHP
The latest version of MediaWiki runs on any version of PHP to PHP 5.4. PHP 5.5 and greater have unresoved issues and might cause some functions to break.

MediaWiki の最近のバージョンでは、PHP 5.0、5.1、5.2 がサポートしていない機能を含んでいるため、これらのバージョンで実行しようとすると失敗します.

PHP 4 is unsupported since MediaWiki 1.7, and attempts to run it will fail. If you are unable to upgrade your environment to PHP 5, you must use MW 1.6; note that this release has security issues and is no longer supported by the MW community (neither is PHP 4 supported by the PHP one).

MediaWiki 1.18 and later may additionally target the HipHop compiler, which will impose a few additional constraints on compatibility and coding style.

データベース
MediaWiki はさまざまな種類のデータベース サーバーと互換性があります. MySQL への対応に特に力を入れています.

Support for any other database software ranges from dubious to stable; architectures for which have at least some support. Anything other than MySQL is not recommended for production use at this point.

ウェブサーバー
MediaWiki is broadly compatible with all major web servers that can invoke PHP. Compatibility is strongest for Apache and IIS. So long as the webserver version supports the required PHP version based on the matrix outlined here.

グレードA
All current major web browsers are compatible with most versions of MediaWiki. "Grade A" functionality is maintained for the following browser requirements:


 * Internet Explorer 9 以降
 * Firefox 4 以降
 * Safari 5.0 以降
 * Opera 11.6 以降
 * Chrome 17 以降

グレードB
Basic compatibility is maintained for legacy versions of web browsers until they fall to a sufficiently low level of utilisation (typically under 0.1%). In particular, compatibility is currently maintained for:
 * Internet Explorer 6+


 * Firefox 2.0 以降
 * Safari 3.0 以降
 * Opera 10.0 以降
 * Chrome 9 以降

Browsers which are not explicitly marked as incompatible are often generally compatible. Support is not guaranteed for old non-standards compatible browsers and issues with those browsers might not be resolved. Security vulnerabilities affecting any browser will be addressed if possible.

携帯機器版ブラウザー
In addition, MediaWiki supports reading and navigation (but not necessarily contributing) in several mobile browsers. Be aware that mobile versions of Safari, Firefox, and Opera are not quite the same as their desktop equivalents. While built on the same rendering engines, they may lack support for some features, add support for other mobile-specific features (such as touch events), or alter the display of pages to better fit on a small screen.

CSS
MediaWiki は CSS3 マークアップを処理できないユーザー エージェントと互換性があります. これらの CSS を処理できるブラウザーで使用できる追加的な機能が一部あります.

JavaScript
MediaWiki is accessible to user agents which do not process JavaScript. MediaWiki degrades gracefully and all essential functionality works without JavaScript, although some things might be less convenient.

テキスト版ブラウザー
MediaWiki は、テキストのみのブラウザー (Lynx など) やインタープリター (JAWS など) でもアクセスできます. 一部、使用できない機能があります.

Note that older text-only browsers like Lynx are not representative of text-to-speech assistive tools like JAWS and other screen readers, which tie into browsers such as Internet Explorer and Firefox through their accessibility interfaces and make use of CSS styles, dynamic JavaScript, etc.
