Question

I am having a need of getting http response code for page urls from sitemap.xml file. When i get the response code by my cron process it returns 403 (Known as access forbidden : though i can access the passed url from browser).

But if I run the same code from my localhost, it returns the correct http response code (i.e 200).

Why is the difference in returning different http response code from local host and from server ?? How to resolve the problem ?

The code for extracting the http response code is as below.

function check_response_code() {
    $pageurl='http://www.certona.com/online-merchandising/';
    $trimurl = '';
    $start = '';
    $end = '';
    $total = '';

    $start = microtime(true);
    $response_code = '';
    if (!stristr($pageurl, "http://"))
    {
        if (!stristr($pageurl, "https://"))
        {
            $trimurl = "http://" . $pageurl;
        } else
        {
            $trimurl = $pageurl;
        }
    } else
    {
        $trimurl = $pageurl;
    }
    $curl = curl_init();
    //don't fetch the actual page, you only want headers

    curl_setopt($curl, CURLOPT_URL, $trimurl);
    curl_setopt($curl, CURLOPT_NOBODY, true);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_FILETIME, true);

    $result = curl_exec($curl);

    $timestamp = curl_getinfo($curl, CURLINFO_FILETIME);
    $response_code = curl_getinfo($curl, CURLINFO_HTTP_CODE);
    $mime_type = curl_getinfo($curl, CURLINFO_CONTENT_TYPE);
    $end = microtime(true);
    $total = round($end - $start, 5);

    if ($timestamp != -1)
    { //otherwise unknown
        $arr=array(date("Y-m-d H:i:s", $timestamp), $response_code, $total, $mime_type); //etc
    } else
    {
        $arr=array("", $response_code, $total, $mime_type);
    }
    echo "<pre>";
    print_r($arr);
    echo "</pre>";
}

Thank you..

Am not sure but your code seems to work fine

Try

check_response_code();

function check_response_code() {
    $pageurl='http://www.certona.com/online-merchandising/';
    $curl = curl_init($pageurl);
    curl_setopt($curl, CURLOPT_NOBODY, true);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_FILETIME, true);

    $result = curl_exec($curl);
    $info = curl_getinfo($curl);
    $info['filetime'] = date("Y-m-d H:i:s", $info['filetime']);
    echo "<pre>";
    print_r($info);
    echo "</pre>";
}

Output
