Simply get the HTTP Status Code in PHP

[johnsmith153]

I want to get the HTTP status code of the current request in PHP (e.g. 301, 303, 404, 200 etc.)

 

I don't want to use cURL for other websites, just use PHP to get the status code of that request on the domain PHP is on.

 

Also, I'm considering doing this on every page request, so an idea of how expensive the call to get the status code is would be good (so if I am using cURL I guess it's not a good idea). Obviously I'll only do it on every request if it's a quick process.

 

Thanks.

It's always 200 unless you change it yourself...

 

You're talking about the status code of the page that PHP is currently rendering, right? Of the script that's executing?

[johnsmith153]

Yes, the page that is currently executing, so this would be ideal:

 

$status_code = get_php_status_code();

if($status_code == "301") {
  echo "this was a redirect";
}

//this is just an example

 

Thanks

So, can you do it?

Can I do what?

 

If you're using 5.4 then you have http_response_code, otherwise you'll have to write something yourself. Assuming you'd be writing PHP code for this, you wouldn't be able to use header() directly as your new code wouldn't know of the new response code.

http://www.php.net/manual/en/function.apache-request-headers.php returns the headers of the current request.

[requinix]

http://www.php.net/manual/en/function.apache-request-headers.php returns the headers of the current request.

But the request, not the response. (Which is what OP meant since requests don't have status codes.)

http://www.php.net/manual/en/function.headers-list.php then.
