Proxy Checker (for Proxy List)

xrvel · 28 June, 2009, 17:16 PM

Here is a code to check some proxies in your proxy list.
It checks dead or not, and the reciprocal status

Edit :
It can be used for all proxy listing script (devduke's or other's).
Because the input is only plain URL.
And the output is a basic array.

But it should be customized and modified further (which i can not write here, because it depends to each proxy list script) including :
- update the proxy status on the database.

PHP Code:


			
<?php
//
// Proxy list cleaner
//
// Author : Xrvel (xrvel.com)
//
// This cron script check each proxy and :
// - update its status (dead or alive).
// - check backlink
//
// Requirement :
// - PHP CURL
//
// Note that this function only check the URL.
// It does not mark it on database whether it is dead or not,
// So you must add your custom code yourself if you want
// it to automatically mark dead proxies on your database.
//

// Do not modify start
ob_start();
header('Expires: Mon, 26 Jul 1997 05:00:00 GMT');
header('Last-Modified: '.gmdate('D, d M Y H:i:s',time()-60).' GMT');
header('Cache-Control: private, no-store, no-cache, must-revalidate, pre-check=0, post-check=0, max-age=0');
header('Pragma: no-cache');
//error_reporting(E_ALL);
ignore_user_abort(true);
set_time_limit(60 * 5);
session_start();
// Do not modify end

//
// Here is the proxy URL which you want to check
// You can customize it to receive URL from form / database
// Could be a string, or an array of string
//

/*
$proxy_url = array(
    'http://someonesproxy1.com',
    'http://someonesproxy2.com',
    'http://someonesproxy3.com'
);
*/

$proxy_url = 'http://example.com';

//
// Reciprocal is marked as "found"
// if this string is found in the proxy's page
// But this script can not detect whether the reciprocal
// is on HTML comment / hidden section or such.
// You must manually check it (human editor)
//
$reciprocal_match = 'yourdomain.com';

// Example :
$result = check_the_proxy($proxy_url);
echo '<pre>', print_r($result, true), '</pre>';

//
// No need to modify anything below
//

//
// MAIN FUNCTION START
//
// Return type : array of mixed

function check_the_proxy($proxy_url) {
    global $reciprocal_match;

    $proxies = array();// everything will be put here

    if (is_string($proxy_url)) {
        $proxy_url = array($proxy_url);
    }

    foreach ($proxy_url as $u) {
        $proxies[] = array(

    }
    unset($proxy_url);

    $ch = curl_init();

        $proxies[$i]['http_code'] = $info['http_code'];
        $proxies[$i]['download_content_length'] = $info['download_content_length'];

        // Check is dead ?
        if ($info['http_code'] == '200' || $info['http_code'] == '300' || $info['http_code'] == '301') {
            $proxies[$i]['is_dead'] = 0;
        } else {

        }

        // Check reciprocal

        $i++;
    }    
    curl_close($ch);
    unset($ch, $res);

    return $proxies;
}
// MAIN FUNCTION END
?>

But it should be customized further, according to each proxy list script, including :
