Question

I know in php 5.4 there is a new function http_response_code(), but in prior versions how would you get a response code you just set?

Similar to Is there any way to get the current HTTP response code from PHP?

I have this need:

 //sometime earlier
 header('HTTP/1.1 404 Not Found');


//sometime later, detect if error was set
$status = some_magic_way_to_find_status();

Does anyone have a way in php 5.3 or below to do this?

I don’t think it’s possible.

You could wrap the header() function:

function my_status_header($setHeader=null) {
    static $theHeader=null;
    //if we already set it, then return what we set before (can't set it twice anyway)
    if($theHeader) {return $theHeader;}
    $theHeader = $setHeader;
    header('HTTP/1.1 '.$setHeader);
    return $setHeader;
}

Or, of course, you could always upgrade to PHP5.4.
