Hide index php
STEP 1: Add the following code to .htaccess file:
RewriteEngine On
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-f
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-d
RewriteRule ^(.*)$ %{DOCUMENT_ROOT}/MW-DIRECTORY/index.php [L]
Replace MW-DIRECTORY with the name of directory wherein you have installed MediaWiki (i.e. the directory which contains MediWiki files and folders like extensions, cache, maintenance, skins etc.)
Where to put .htaccess? The .htaccess file should be placed in the MediaWiki installation directory.
STEP 2: Now add the following code in LocalSettings.php
$wgScriptPath = “/MW-DIRECTORY“;
$wgScriptExtension = “.php”;
$wgArticlePath = “{$wgScriptPath}/$1”;
$wgUsePathInfo = true;
Replace MW-DIRECTORY with the MediaWiki installation directory. Your LocalSettings.php file might already contain the first two lines of the code given above. If these lines are already present –just add the second and third line right below the existing lines.
