Curl and sended response

Hello guys..

I spend a whole night searching and trying, please give some help...

I want to check the existance of some media files (avi, mp4, flv .....)
if the files exists or not exist anymore.

I have the direct links of these media files, so here's the code that i used :

$userAgent ='# IE 6 - Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)';
$ch = curl_init();
curl_setopt ($ch, CURLOPT_USERAGENT, $userAgent);
curl_setopt ($ch, CURLOPT_URL, "LINK OF THE MEDIA FILE");
curl_setopt ($ch, CURLOPT_HEADER, 0);

curl_exec ($ch);
$result=curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close ($ch);
echo $result;

Code (markup):

when the file don't exist the $result returns '404' but i don't want the page of the browser appear :

The page cannot be found
The page you are looking for might have been removed, had its name changed, or is temporarily unavailable.

Please try the following:

............................................

Code (markup):

And when the file exist the page become a huge ascii code... and the browser become not responding...

Like I said i want just the ode send '404' for not found files and 'OK' for founded files.

Did i miss something.
Thanks for your help.

 

You'll need to fetch the response codes through the header of the site.

Found this example on PHP.net

<?php

/*==================================
Get url content and response headers (given a url, follows all redirections on it and returned content and response headers of final url)

@return    array[0]    content
        array[1]    array of response headers
==================================*/
function get_url( $url,  $javascript_loop = 0, $timeout = 5 )
{
    $url = str_replace( "&amp;", "&", urldecode(trim($url)) );

    $cookie = tempnam ("/tmp", "CURLCOOKIE");
    $ch = curl_init();
    curl_setopt( $ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1" );
    curl_setopt( $ch, CURLOPT_URL, $url );
    curl_setopt( $ch, CURLOPT_COOKIEJAR, $cookie );
    curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, true );
    curl_setopt( $ch, CURLOPT_ENCODING, "" );
    curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
    curl_setopt( $ch, CURLOPT_AUTOREFERER, true );
    curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false );    # required for https urls
    curl_setopt( $ch, CURLOPT_CONNECTTIMEOUT, $timeout );
    curl_setopt( $ch, CURLOPT_TIMEOUT, $timeout );
    curl_setopt( $ch, CURLOPT_MAXREDIRS, 10 );
    $content = curl_exec( $ch );
    $response = curl_getinfo( $ch );
    curl_close ( $ch );

    if ($response['http_code'] == 301 || $response['http_code'] == 302)
    {
        ini_set("user_agent", "Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1");

        if ( $headers = get_headers($response['url']) )
        {
            foreach( $headers as $value )
            {
                if ( substr( strtolower($value), 0, 9 ) == "location:" )
                    return get_url( trim( substr( $value, 9, strlen($value) ) ) );
            }
        }
    }

    if (    ( preg_match("/>[[:space:]]+window\.location\.replace\('(.*)'\)/i", $content, $value) || preg_match("/>[[:space:]]+window\.location\=\"(.*)\"/i", $content, $value) ) &&
            $javascript_loop < 5
    )
    {
        return get_url( $value[1], $javascript_loop+1 );
    }
    else
    {
        return array( $content, $response );
    }
}

?>

Code (markup):

So, you can check $response['http_code'] to see if it's a 404.
