$uri = $_SERVER['REQUEST_URI']?$_SERVER['REQUEST_URI']:($_SERVER['PHP_SELF']?$_SERVER['PHP_SELF']:$_SERVER[ 'SCRIPT_NAME']);
//Put $_SERVER['REQUEST_URI'];$_SERVER['PHP_SELF'];$_SERVER['SCRIPT_NAME'] through ternary operation and give the result to $url
//$_SERVER is also an array, you can print it and you will know what it is used for. Only three array elements are involved here
//$_SERVER['REQUEST_URI']; //REQUEST_URI :/mysite/->Site directory?
//$_SERVER['PHP_SELF']; //PHP_SELF:/mysite/index.php->The file name of the currently executing script
//$_SERVER['SCRIPT_NAME']; //SCRIPT_NAME:/mysite/index.php->Path containing the current script
