Fixed issue: Only variables should be passed by reference

If you getting issue “Only variables should be passed by reference” it comes because you are using direct value from one function to other function. So first get value from one function and assigned to variable and then that variable used in next function.

Issue:

if(!empty($_SERVER['REQUEST_URI']) && $_SERVER['REQUEST_URI'] != '/')
{
	$url =  end( array_filter( explode( DS , $_SERVER['REQUEST_URI']) ) );
}

Fixed:

if(!empty($_SERVER['REQUEST_URI']) && $_SERVER['REQUEST_URI'] != '/')
{
	$uri =  array_filter( explode( DS , $_SERVER['REQUEST_URI']) );
	$url = end($uri);
}

Cheer 🙂
