Description Author

This class can check is a HTTP proxy is working.

It can connect to a given HTTP proxy server and send a HTTP request to a test page of the current site to see if the request is successfully forwarded to the the test page.

If the proxy server returns the expected response, the class analyzes the response to determine if the proxy server is transparent and if omits the origin user details to make the access anonymous.

# Proxy Checker
Check if a proxy is working, its type (transparent, anonymous, elite) and other info (time, http code, redirect count, speed etc.)

# Usage
## Proxy format

type - http, socks4, socks5 <br />
password and type if not required <br /> <br />

Some examples:


## Check one proxy

    $pingUrl = '';
    $proxy = '';

    $proxyChecker = new ProxyChecker($pingUrl);
    $results = $proxyChecker->checkProxy($proxy);

## Check several proxies

    $pingUrl = '';
    $proxies = array('', '');

    $proxyChecker = new ProxyChecker($pingUrl);
    $results = $proxyChecker->checkProxies($proxies);

# Result
## Allowed/Disallowed
Array allowed/disallowed operations of proxy (get, post, referer, cookie, user_agent), for example:

    'allowed' => array (
        0 => 'get',
        1 => 'post',
        2 => 'referer',
        3 => 'user_agent'

    'disallowed' => array (
        0 => 'cookie'

## Proxy level
elite - connection looks like a regular client <br />
anonymous - no ip is forworded but target site could still tell it's a proxy  <br />
transparent - ip is forworded and target site would be able to tell it's a proxy  <br />

    'proxy_level' => 'elite',

## Other info
Other proxy info - time, http code, redirect count, speed etc:

    'info' => array (
      'content_type' => 'text/html',
