php模擬post提交數據

 　　php模擬post提交數據,用處很多,可用來網站的采集,登陸等等

　　//以我項目中的論壇登錄為例

　　function A_bbslogin($user_login,$password,$host,$port="80"){

　　//需要提交的post數據

　　$argv = array(

　　'cookie' => array('user_login' =>$user_login, 'password' => $password,'_wp_http_referer'=>'/bbpress/','re'=>'','remember'=>true)

　　);

　　foreach($argv['cookie'] 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); //以下是自己的邏輯代碼,這裡主要是模擬cookie,可用來同步登陸

　　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);

　　}
