For a quick copy-paste you can use the following line, which was generated using

To force a file, such as "LocalSettings.php" to be re-read when touched, you can use the following code (MW < 1.17):
# When you make changes to this configuration file, this will make sure that cached pages are cleared. $wgCacheEpoch = max( $wgCacheEpoch, gmdate( 'YmdHis', @filemtime( __FILE__ ) ) );
Note: Since version 1.17 of MediaWiki, you should use
$wgInvalidateCacheOnLocalSettingsChange to automatically invalidate cache whenever "LocalSettings.php" is modified.
