Detailed Description

Check PHP Version, as well as for composer dependencies in entry points, and display something vaguely comprehensible in the event of a totally unrecoverable error.

Note: Since we can't rely on anything external, the minimum PHP versions and MW current version are hardcoded in this class.; This class uses setter methods instead of a constructor so that it can be compatible with PHP 4 through PHP 8 (without warnings).

◆ triggerError()

PHPVersionCheck::triggerError	(		$web,
			$cliText )

Display something vaguely comprehensible in the event of a totally unrecoverable error.

Does not assume access to anything; no globals, no autoloader, no database, no localisation. Safe for PHP4 (and putting this here means that WebStart.php and GlobalSettings.php no longer need to be).

This function immediately terminates the PHP process.

Parameters

string[]	$web	(string) intro: Short error message, displayed on top. (string) longTitle: Title for the longer message. (string) longHtml: The longer message, as raw HTML.
string	$cliText
