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

This article describes how to simulate post or get requests using fsocket, a custom php class. 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 (! Feof ($ fp) {line line = fgets ($ fp, 1024); if (substr ($ line, 0, 12) = 'set-Cookie :') {$ cookies [] = $ this-> _ setCookie (substr ($ line, 12);} $ reHeader. = $ line; if (substr ($ line, 0, 16) = 'content-Length: ') {$ maxlen = intval (substr ($ line, 16, -2);} if ($ line = "\ r \ n" | $ line = "") break;} return $ maxlen ;} /** get the body content of the returned data */private function _ getDataBody (& $ fp, $ maxlen) {$ reData = ""; while (! Feof ($ fp) {$ line = fgets ($ fp, $ maxlen + 1); $ reData. = $ line; if (strlen ($ line) <$ maxlen) $ maxlen = $ maxlen-strlen ($ line); else break;} return $ reData ;} /** set and return the content of the header to be sent */public function get_HeaderInfo ($ host, $ type = 'get', $ file = '/', $ params = array (), $ head = array (), $ cookies = array () {$ _ params = $ _ cookies = ''; if (is_array ($ params) {foreach ($ params as $ key => $ value) {$ _ params. = "&". $ key. "= ". url Encode ($ value) ;}$ _ params = (strlen ($ _ params)> 1 )? Substr ($ _ params, 1): '';} else if (is_string ($ params) {$ _ params = urlencode ($ params );} foreach ($ cookies as $ key => $ value) {$ _ cookies. = ";". $ key. "= ". urlencode ($ value) ;}$ _ cookies = (strlen ($ _ cookies)> 2 )? Substr ($ _ cookies, 2): ''; $ file. = ($ type = 'get ')? ($ _ Params = ''? '':'? '. $ _ Params): ''; $ header = $ type. "". $ file. "HTTP/1.1 \ r \ n"; $ header. = "Host :". $ host. "\ r \ n"; // $ header. = "Referer :". get_ip (). "\ r \ n"; // $ header. = "X-Forwarded-:". get_ip (). "\ r \ n"; $ header. = ($ type = 'get ')? '':" Content-Type: application/x-www-form-urlencoded \ r \ n "; if (is_array ($ head) & $ head! = Array () {foreach ($ head as $ k => $ v) {$ header. = $ k. ":". $ v. "\ r \ n" ;}}$ header. = "Content-Length :". strlen ($ _ params ). "\ r \ n"; if ($ _ cookies! = '') $ Header. = "Cookie :". $ _ cookies. "\ r \ n";/* foreach ($ _ SERVER as $ name => $ value) {if (substr ($ name, 0, 5) = 'HTTP _ '& $ name! = 'HTTP _ host') {$ header. = str_replace ('', '-', ucwords (strtolower (str_replace ('_','', substr ($ name, 5 ))))). ":". $ value. "\ r \ n" ;}} */$ header. = "Connection: Close \ r \ n"; $ header. = $ _ params. "\ r \ n"; return $ header;}/** send and return the result Array */public function get_SendData ($ host, $ port = 80, $ header = '') {if (function_exists ('fsockopen') {$ fp = fsockopen ($ host, $ port, $ errno, $ errstr, 10 );} else if (functio N_exists ('pfsockopen') {$ fp = pfsockopen ($ host, $ port, $ errno, $ errstr, 10 );} else if (function_exists ('stream _ socket_client ') {$ fp = stream_socket_client ($ host. ':'. $ port, $ errno, $ errstr, 10);} else {$ fp = $ this-> _ fsockopen ($ host, $ port, $ errno, $ errstr, 10) ;}$ fp = fsockopen ($ host, $ port, $ errno, $ errstr, 10); if (! $ Fp) return array ('header' => '', 'data' => $ errstr. "---> ". $ 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";print_r($header);print_r($data);echo "-->\r\n";*/var_dump($header);var_dump($data);
