[SOLVED] How to analyze headers in PHP

Issue

I'm using a file_get_contents to interact with an API for simple GET requests... however sometimes it throws headers signifying there's been an error. How can I get these headers and determine if there's a problem?

Solution

Use curl instead of file_get_contents.

See: http://www.php.net/manual/en/curl.examples-basic.php

I imagine if your communicating with a REST Api then your actaully wanting the Http Status code returned. In which case you could do something like this:

<?php
$ch = curl_init("http://www.example.com/api/users/1");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
if(curl_getinfo($ch, CURLINFO_HTTP_CODE) == 501) {
    echo 'Ops it not implemented';
}
fclose($fp);
?>
