MediaWiki add GeSHi Extension

I became a fun of GeSHi.

Extension:SyntaxHighlight GeSHi tag displays formatted source code with the tag.

cd /var/www/html/wikidocs/extensions/
git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/SyntaxHighlight_GeSHi.git

vi LocalSettings.php

require_once("$IP/extensions/SyntaxHighlight_GeSHi/SyntaxHighlight_GeSHi.php");

# service httpd restart

On the wiki page, you can now use "syntaxhighlight" elements:

    $v = "string";    // sample initialization
?>
html text
    echo $v;         // end of php code
?>
