    CURL Connections with Tor

Install Apache, PHP, CURL & Tor with apt-get
sudo apt-get install -y apache2 php5 php5-curl tor
Tor creates a proxy on your mashine with port 9050 for SOCKS5 connections.
class Proxy {

	private $ch, $proxy;

	function __construct() 
	{
		$torSocks5Proxy = "socks5://127.0.0.1:9050";

		$this->ch = curl_init();

		curl_setopt( $this->ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5 );
		curl_setopt( $this->ch, CURLOPT_PROXY, $torSocks5Proxy );
		curl_setopt( $this->ch, CURLOPT_SSL_VERIFYPEER, false );
		curl_setopt( $this->ch, CURLOPT_FOLLOWLOCATION, true );
		curl_setopt( $this->ch, CURLOPT_RETURNTRANSFER, false );
		curl_setopt( $this->ch, CURLOPT_HEADER, false );
	}

	public function curl( $url, $postParameter = null ) 
	{
		if( sizeof( $postParameter ) > 0 )
			curl_setopt( $this->ch, CURLOPT_POSTFIELDS, $postParameter );

		curl_setopt( $this->ch, CURLOPT_URL, $url );
		return curl_exec( $this->ch );
	}
	
	public function changeProxyIdentity()
	{
		$ip      = '127.0.0.1';
		$port    = '9050';

		$fp = fsockopen(
		    $ip, $port,
		    $error_number,
		    $err_string, 10
		);

		if (!$fp) {
		    echo "Error while changing Tor proxy identity: {$error_number} : {$err_string}";
		    return false;
		} else {
		    fwrite($fp, "AUTHENTICATE\n");
		    $received = fread($fp, 512);
		    fwrite($fp, "signal NEWNY\n");
		    $received = fread($fp, 512);
		}

		fclose($fp);

		return $received;

	function __destruct() 
	{

}
Use the Proxy class for a GET request.
$proxy = new Proxy();
$proxy->changeProxyIdentity();
echo $proxy->curl( "http://check.torproject.org" );
Use the Proxy class for a POST request
$proxy = new Proxy();
$parameter = array(
	'parameter1' => 'value1',
	'parameter2' => 'value2'
);
echo $proxy->curl( "http://check.torproject.org", $parameter );
