(PHP ActiveX) TCP Socket Connect through HTTP Proxy

Demonstrates how to connect through an HTTP 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 connect through an HTTP proxy, set the HttpProxyHostname
// and HttpProxyPort properties to the hostname (or IP address)
// and port of the HTTP proxy.  Typical port numbers used by
// HTTP proxy servers are 3128 and 8080.
$socket->HttpProxyHostname = 'www.my-http-proxy.com';
$socket->HttpProxyPort = 3128;

// Important:  Your HTTP proxy server must allow non-HTTP
// traffic to pass.  Otherwise this does not work.

// Connect (via the HTTP proxy) 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 ficticious 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";
