Make update.php and install.php use wfPHPVersionError() and reorganise it
update.php and install.php now use wfPHPVersionError()
Moved to wfPHPVersionError( cli ) the suggestion of another binary name.
Old PHP versions won't have $_SERVER superglobal, hardcode HTTP/1.0 in that case.
Store in a variable the minimum version of PHP supported by MediaWiki.
Changed PHP_VERSION to phpversion(), although it doesn't matter for the version
ranges this works.
phpversion() has been present since PHP-2.0
PHP_VERSION was added in PHP 3.0RC5
On its current form in PHP 4 it was moved from Zend/zend_constants.c
to main/main.c by Zeev in commits
71dddd7db7e768ae8145e085fcbb6b6db4a1c40a and
fb1c77bd4f8a636ba47d720f8ca65fc6baae836d (1999-12-17)
It had been commented there since the beginning of svn history (1999-04-07)
The earliest version we can target seems to be PHP 4.1.0
PHP 4.0.0 produces a parse error on a require_once not followed by a literal
path (although you can use require with an expression), plus its dirname()
is quite dumb, and wouldn't provide the right path (would require you to call
"php ./update.php" from maintenance folder, not "php update.php" or
"php maintenance/update.php" from the main dir)
Replacing pathinfo( $_SERVER['SCRIPT_NAME'], PATHINFO_DIRNAME ); into a pathinfo()
to another variable since pathinfo( "", PATHINFO_DIRNAME ); core dumps in PHP 4.1.0
(works if $path is not empty)
The value of the pragma directive is 'no-cache', not 'nocache'. See section 14.32
