Use the following function call forms instead - the commented ones are correct alternatives too. See call_user_func and call_user_func_array.
if (!empty($url[2])) {
$object->{$url[1]}($url[2]);
// Alternative 1
// call_user_func(array($object, $url[1]), $url[2]);
// Alternative 2
// call_user_func_array(array($object, $url[1]), array($url[2]));
} else {
$object->{$url[1]}();
// Alternative 1
// call_user_func(array($object, $url[1]));
// Alternative 2
// call_user_func_array(array($object, $url[1]), array());
}
You said:
its work on localhost but when i uploaded on my host not working what i do ?
That has to do with the error reporting activation or with difference in PHP version.
