Web installer was not checking for unsupported PHP versions. In those cases the script should terminate or the installation will break (e.g. syntax errors for PHP4). Installer::doEnvironmentChecks() no longer checks for PHP version since it has already been done by the entry scripts (both in cli and web modes) Installer::MINIMUM_PHP_VERSION has been removed since it is no longer used. Message config-env-php-toolow is no longer used and it has been removed Change-Id: I9227868bd2bd4e13bad6b95ad581be3ada71c94e

<a href="https://www.mediawiki.org/wiki/Download">download</a> an older version

of MediaWiki from our website. See our
