(PHP Extension) Socket/SSL/TLS through SOCKS5 / SOCKS4 Proxy

Demonstrates how to use the Chilkat Socket/SSL/TLS component/library with a SOCKS5 or SOCKS4 proxy server.

Chilkat PHP Downloads PHP Extension for Windows, Linux, MacOS, Alpine Linux, Solaris

<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

$socket = new CkSocket();

// To use a SOCKS4 or SOCKS5 proxy, simply set the following
// properties prior to calling Connect.  The connection may be SSL/TLS or 
// non-secure - both will work with a SOCKS proxy.
// The SOCKS hostname may be a domain name or 
// IP address:
$socket->put_SocksHostname('www.mysocksproxyserver.com');
$socket->put_SocksPort(1080);
$socket->put_SocksUsername('myProxyLogin');
$socket->put_SocksPassword('myProxyPassword');
// Set the SOCKS version to 4 or 5 based on the version
// of the SOCKS proxy server:
$socket->put_SocksVersion(5);
// Note: SOCKS4 servers only support usernames without passwords.
// SOCKS5 servers support full login/password authentication.

// Connect to port 5555 of 192.168.1.108.
// hostname may be a domain name or IP address.
$hostname = '192.168.1.108';
$ssl = false;
$maxWaitMillisec = 20000;
$success = $socket->Connect($hostname,5555,$ssl,$maxWaitMillisec);
if ($success != true) {
    print $socket->lastErrorText() . "\n";
    exit;
}

// Set maximum timeouts for reading an writing (in millisec)
$socket->put_MaxReadIdleMs(10000);
$socket->put_MaxSendIdleMs(10000);

// The server (in this example) is going to send a "Hello World!" 
// message.  Read it:
$receivedMsg = $socket->receiveString();
if ($socket->get_LastMethodSuccess() != true) {
    print $socket->lastErrorText() . "\n";
    exit;
}

// Close the connection with the server
// Wait a max of 20 seconds (20000 millsec)
$success = $socket->Close(20000);

print $receivedMsg . "\n";
