Check headers in PHP cURL server response

Question

I've been using PHP curl to get data I need from remote website. Here is the cURL function I used:

function get_content($adr)  
    {  
       $ch = curl_init();  

       curl_setopt ($ch, CURLOPT_URL, $adr);  
       curl_setopt($ch,CURLOPT_USERAGENT,'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');
       curl_setopt ($ch, CURLOPT_HEADER, 0);  

       ob_start();  

       curl_exec ($ch);  
       curl_close ($ch);  
       $string = ob_get_contents();  

       ob_end_clean();  

       return $string;      

    }  
$myrul = "http://remoteurl.com";
$result = get_content($myrul);

But how do I get the headers for the response?

I assume it's "how do I see the headers returned from the curl_exec() function?" — WWW

If my comment above is correct, change:

curl_setopt($ch, CURLOPT_HEADER, 0);

to:

curl_setopt($ch, CURLOPT_HEADER, 1);

and parse the returned headers out however you see fit. Note that just changing the above in your function will return both headers and content, so if you want only headers returned:

function http_head_curl($url,$timeout=10)
{
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_TIMEOUT, $timeout); // in seconds
    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLOPT_NOBODY, 1);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $res = curl_exec($ch);
    if ($res === false) {
        throw new RuntimeException("cURL exception: ".curl_errno($ch).": ".curl_error($ch));
    }
    return trim($res);
}
