Four Methods for simulating data submission using post in php

The code is as follows:

Copy code

<? Php   // Use a program to log on to a forum as an example. Function bbslogin ($ user_login, $ password, $ host, $ port = "80 "){ // The post data to be submitted $ Argv = array ('cookie '=> array ('User _ login' => $ user_login, 'password' => $ password, '_ wp_http_referer' => '/bbpress/', 're' => '', 'Remember '=> true )); Foreach ($ argv ['cookies'] as $ key => $ value ){ $ Params [] = $ key. '='. $ value;     } $ Params = implode ('&', $ params ); $ Header = "POST/bbpress/bb-login.php HTTP/1.1rn "; $ Header. = "Host: $ host: $ portrn "; $ Header. = "Content-Type: application/x-www-form-urlencodedrn "; $ Header. = "Content-Length:". strlen ($ params). "rn "; $ Header. = "Connection: Closernrn "; $ Header. = $ params; $ Fp = fsockopen ($ host, $ port ); Fputs ($ fp, $ header ); While (! Feof ($ fp )){ $ Str = fgets ($ fp ); // The following is your own logic code. Here we mainly simulate cookies for synchronous login. If (! (Strpos ($ str, "Set-Cookie:") === false )){ $ Tmparray = explode ("", $ str ); $ Cookiearray = explode ("=", $ tmparray [1]); $ Cookiepaths = explode ("=", $ tmparray [6]); $ Cookiename = urldecode ($ cookiearray [0]); $ Cookievalue = urldecode (substr ($ cookiearray [1], 0, strlen ($ cookiearray [1])-1 )); $ Cookietime = time () + 3600*24*7; $ Cookiepath = urldecode (substr ($ cookiepaths [1], 0, strlen ($ cookiepaths [1])-1 )); Setcookie ($ cookiename, $ cookievalue, $ cookietime, $ cookiepath );         }     } Fclose ($ fp ); } ?>     <?
