This example uses the fsockopen to connect to an url which can be via any port (even the ssl one), posts some data and reads the output page as well as the headers.

The source code:
<html> <body> <h1>Search using Google from a remote spot</h1> <p>The search term is: <i>your search term</i></p> <? $url= 'www.linkstraffic.net'; /*We encode the search term in case there are special characters*/ $searchterm=urlencode('design'); $data= 'item='.$searchterm; /*We connect to Linkstraffic and do a search from our server*/ $sock = fsockopen($url, 80, $errno, $errstr, 30); if (!$sock) die("$errstr ($errno)\n"); /*we use the GET method to proceed - We tell the server we are using a Mozilla browser on Windows*/ fputs($sock, "GET /seek.php HTTP/1.0\r\n"); fputs($sock, "Host: www.linkstraffic.net\r\n"); fputs($sock, "User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1) Gecko/20061010 Firefox/2.0\r\n"); fputs($sock, "Content-type: application/x-www-form-urlencoded\r\n"); /*Fill in details about the size of the form data to be sent*/ fputs($sock, "Content-length: ".strlen($data)."\r\n\r\n"); fputs($sock, "Connection: close\r\n\r\n"); /*Finally send the data over the socket:*/ fputs($sock, $data."\r\n"); fputs($sock, "\r\n"); /*Let's go throught the resulting page*/ //First the headers $headers=""; while($str=trim(fgets($sock, 4096))) { $headers .= $str."<br />"; } //Then the body of the page $body= ""; while (!feof($sock)) { $body.= fgets($sock, 4096); } fclose($sock); //Write down the results: echo '<hr><p><b>Headers:</b><br />'.$headers.'</p>'; echo '<div style="width:auto;overflow:scroll;height:auto">'.$body.'</div>'; ?> </body> </html>

Notes:
- we use the fsockopen and the fputs functions to open a socket and write throught it;
- in order to use the ssl port, we will need to have openssl compiled into PHP;
- you can retrieve and send session and cookies ids from reading and writing in headers; and often you will need these data in order to access the results from a post request.
