(PHP ActiveX) 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 ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

<?php

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

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Socket')
$socket = new COM("Chilkat.Socket");

// 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->SocksHostname = 'www.mysocksproxyserver.com';
$socket->SocksPort = 1080;
$socket->SocksUsername = 'myProxyLogin';
$socket->SocksPassword = 'myProxyPassword';
// Set the SOCKS version to 4 or 5 based on the version
// of the SOCKS proxy server:
$socket->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 = 0;
$maxWaitMillisec = 20000;
$success = $socket->Connect($hostname,5555,$ssl,$maxWaitMillisec);
if ($success != 1) {
    print $socket->LastErrorText . "\n";
    exit;
}

// Set maximum timeouts for reading an writing (in millisec)
$socket->MaxReadIdleMs = 10000;
$socket->MaxSendIdleMs = 10000;

// The server (in this example) is going to send a "Hello World!" 
// message.  Read it:
$receivedMsg = $socket->receiveString();
if ($socket->LastMethodSuccess != 1) {
    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";
