Php user-defined fsocket-like method for simulating post or get requests

This article mainly introduces php user-defined fsocket method for simulating post or get requests. it involves some skills related to php's use of socket to simulate post and get requests. it has some reference value, for more information about how to simulate post or get requests using fsocket, see the example in this article. Share it with you for your reference. The details are as follows:

The zsocket. class. php file is as follows:

<? Phpclass ZSocket {/** Init */private function _ fsockopen ($ host, $ port, & $ errno, & $ errstr, $ timeout) {$ ip = @ gethostbyname ($ host); $ s = @ socket_create (AF_INET, SOCK_STREAM, 0); if (socket_set_nonblock ($ s )) {$ r = @ socket_connect ($ s, $ ip, $ port); if ($ r | socket_last_error () = EINPROGRESS) {$ errno = EINPROGRESS; return $ s ;}$ errno = socket_last_error ($ s); $ errstr = socket_strerror ($ errno); soc Ket_close ($ s); return false;}/** set Cookie */private function _ setCookie ($ cookie) {$ _ cookies = explode (";", $ cookie ); $ _ tmp = explode ("=", $ _ cookies [0]); setcookie ($ _ tmp [0], $ _ tmp [1]); return $ _ cookies;}/** get the returned data header content */private function _ getDataHeader (& $ fp, & $ reHeader, & $ cookies) {$ maxlen = 0; while (!

"---> ". $ errno, 'cookies' => ''); $ reHeader = $ reData =" "; $ cookies = array (); fputs ($ fp, $ header ); $ maxlen = $ this-> _ getDataHeader ($ fp, $ reHeader, $ cookies); $ reData = $ this-> _ getDataBody ($ fp, $ maxlen ); fclose ($ fp); return array ('header' => $ reHeader, 'data' => $ reData, 'cookies' => $ cookies );}}

The demo code is as follows:

$host = 'www.jb51.net';$port = '80';$type = 'POST';$file = '/';$params = '';//include_once('include/zsocket.class.php'); //include$zsk = new ZSocket();$header = $zsk->get_HeaderInfo($host,$type,$file,$params);$data = $zsk->get_SendData($host,$port,$header);/*echo "
 \r\n";*/var_dump($header);var_dump($data);
