HTTP error codes with fopen()?

Hi
Is there a way of retrieving HTTP error codes (404, 401, ...) when opening an url with fopen()?
This function seems to either return a handle (success) or just false (failure).

Cheers!

 

<?php
  $url = 'use your URL here';  
  $fp = fopen($url, 'r');
  
  // The variable $http_response_header is now automagically populated
  print_r($http_response_header);
?>

PHP:

Enjoy!

Thanks a lot Chemo, exactly what I was looking for!

For anyone interested, the full array of $http_response_header looks something like:

[0] => HTTP/1.1 401 Authorization Required
[1] => Date: Sun, 11 Jun 2006 17:18:33 GMT
[2] => Server: Apache/1.3.29 (Unix) PHP/4.4.0
[3] => WWW-Authenticate: Basic realm="Members"
[4] => Connection: close
[5] => Content-Type: text/html; charset=iso-8859-1

Code (markup):

To check the returned HTTP (error) code, do something like:

if (strpos($http_response_header[0], '404') !== false)
     echo "Error: Document not found.";

PHP:

 

You could expand that and use something like this:

	$return_code = @explode(' ', $http_response_header[0]);
	$return_code = (int)$return_code[1];
	 
	switch($return_code){
		case 301:
			// do something
			break;
		case 302:
			// do something
			break;
		case 404:
			// do something
			break;
		default:
			// do something
			break;
	}

Looks like an elegant solution
Is the return code always of the format "HTTPsomething Number Message"?

 

Yes...if it is a 301 or 302 there will be an additional element in the array of the form Location: domain.com/new_url.php. I have that in my switch statement to check the number of redirects and also present the final URL.

 

Huh this doesn't work for me eg

$content = file_get_contents($url);
var_dump($http_response_header);  //issues a notice $http_response_header not defined

//while this one works fine
var_dump(get_headers($url) );

PHP:

this is on PHP 5.1.4 MacOSX

 

So is this an alternative to specifying an ErrorDocument in .htaccess?

 

i think so, this is a good alternative.
