Parse error: syntax error, unexpected T_NAMESPACE, expecting T_STRING in C:\xampp\htdocs\mediawiki\includes\Namespace.php on line 46

First 46 lines here:

/**
 * Provide things related to namespaces
 * @package MediaWiki
 */

/**
 * Definitions of the NS_ constants are in Defines.php
 * @private
 */
$wgCanonicalNamespaceNames = array(
	NS_MEDIA            => 'Media',
	NS_SPECIAL          => 'Special',
	NS_TALK             => 'Talk',

if( is_array( $wgExtraNamespaces ) ) {
	$wgCanonicalNamespaceNames = $wgCanonicalNamespaceNames + $wgExtraNamespaces;
}
