Just a quick note: if you want to use curl_getinfo() with option CURLINFO_HEADER_OUT in order to debug your cURL request, you must add curl_setopt($handle, CURLINFO_HEADER_OUT, true); first while specifying the options.

Keep in mind that for CURLOPT_RETURNTRANSFER it has to be set with curl_setopt() before execution:



This doesn't work:

<?php

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_exec($ch);

var_dump(curl_getinfo($ch,CURLINFO_HEADER_OUT));

?>



This works:

<?php

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLINFO_HEADER_OUT, true);

curl_exec($ch);

var_dump(curl_getinfo($ch,CURLINFO_HEADER_OUT));

?>

There is a constant missing from that list.  CURLINFO_REDIRECT_COUNT will give you the number of redirects it went through if CURLOPT_FOLLOWLOCATION was set.

Here are the response codes ready for pasting in an ini-style file. Can be used to provide more descriptive message, corresponding to 'http_code' index of the arrray returned by curl_getinfo(). 

These are taken from the W3 consortium HTTP/1.1: Status Code Definitions, found at

And an example usage:

<?php

$ch = curl_init(); // create cURL handle (ch)

if (!$ch) {

    die("Couldn't initialize a cURL handle");

}

// set some cURL options

$ret = curl_setopt($ch, CURLOPT_URL,            "http://mail.yahoo.com");

$ret = curl_setopt($ch, CURLOPT_HEADER,         1);

$ret = curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

$ret = curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);

$ret = curl_setopt($ch, CURLOPT_TIMEOUT,        30);



// execute

$ret = curl_exec($ch);



if (empty($ret)) {

    // some kind of an error happened

    die(curl_error($ch));

    curl_close($ch); // close cURL handler

} else {

    $info = curl_getinfo($ch);

    curl_close($ch); // close cURL handler



    if (empty($info['http_code'])) {

            die("No HTTP code was returned"); 

    } else {

        // load the HTTP codes

        $http_codes = parse_ini_file("path/to/the/ini/file/I/pasted/above");

        

        // echo results

        echo "The server responded: <br />";

        echo $info['http_code'] . " " . $http_codes[$info['http_code']];

    }



}

?>
