http://!@#$%^&*().com

This seems to be an invalid URL and in fact browser says its an invalid URL.

But when I fetching this URL via file_get_contents (XAMPP), it gives an exception with “500 Internal Server Error”, since this URL does not exist why am I not getting 404 ?

To check the response I’m using 

$http_response_header

Here is my code:

$url = "http://!@#$%^&*().com";
$contents = @file_get_contents($url);   
print_r($http_response_header);

When I run the same on another machine (WAMP), then it says $http_response_header is an undefined variable.

Anybody has got any idea what’s the problem here?

    You are suppressing errors at the file_get_contents call, the domain you entered is actually invalid as you stated and the function call will return false and trigger the following warning 

    file_get_contents(http://.@#$%^&*().com): failed to open stream: operation failed

    You won’t get a 404 because the domain is invalid and the http request is probably never sent, hence your $http_response_header is empty.

    Maybe a difference in OS or PHP version between XAMPP and WAMP explain why they act differently?

    My advice is first checking the return value of file_get_contents and only when it’s not false continue with inspecting the response headers.
