php模拟post提交数据,用处很多,可用来网站的采集,登陆等等
//以我项目中的论坛登录为例
function A_bbslogin($user_login,$password,$host,$port="80"){
//需要提交的post数据
$argv = array(
'cookie' => array('user_login' =>$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/1.1\r\n";
$header .= "Host:$host:$port\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($params) . "\r\n";
$header .= "Connection: Close\r\n\r\n";
$header .= $params;
$fp = fsockopen($host, $port);
fputs($fp, $header);
while(!feof($fp)) {
$str = fgets($fp); //以下是自己的逻辑代码,这里主要是模拟cookie,可用来同步登陆
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);
}

PHP POST数据的三种方法
php有三种方法可以post数据,分别为Curl、socket、file_get_contents:
/**
* Socket版本
* 使用方法：
* $post_string = "app=socket&version=beta";
* request_by_socket('facebook.cn','/restServer.php',$post_string);
*/
function request_by_socket($remote_server,$remote_path,$post_string,$port = 80,$timeout = 30){
$socket = fsockopen($remote_server,$port,$errno,$errstr,$timeout);
if (!$socket) die("$errstr($errno)");
fwrite($socket,"POST $remote_path HTTP/1.0\r\n");
fwrite($socket,"User-Agent: Socket Example\r\n");
fwrite($socket,"HOST: $remote_server\r\n");
fwrite($socket,"Content-type: application/x-www-form-urlencoded\r\n");
fwrite($socket,"Content-length: ".strlen($post_string)+8."\r\n");
fwrite($socket,"Accept:*/*\r\n");
fwrite($socket,"\r\n");
fwrite($socket,"mypost=$post_string\r\n");
fwrite($socket,"\r\n");
$header = "";
while ($str = trim(fgets($socket,4096))) {
$header.=$str;
}
$data = "";
while (!feof($socket)) {
$data .= fgets($socket,4096);
}
return $data;
}
/**
* Curl版本
* 使用方法：
* $post_string = "app=request&version=beta";
* request_by_curl('http://facebook.cn/restServer.php',$post_string);
*/
function request_by_curl($remote_server,$post_string){
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$remote_server);
curl_setopt($ch,CURLOPT_POSTFIELDS,'mypost='.$post_string);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch,CURLOPT_USERAGENT,"Jimmy's CURL Example beta");
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
/**
* 其它版本
* 使用方法：
* $post_string = "app=request&version=beta";
* request_by_other('http://facebook.cn/restServer.php',$post_string);
*/
function request_by_other($remote_server,$post_string){
$context = array(
'http'=>array(
‘method’=>’POST’,
‘header’=>’Content-type: application/x-www-form-urlencoded’.”\r\n”.
‘User-Agent : Jimmy\’s POST Example beta’.”\r\n”.
‘Content-length: ‘.strlen($post_string)+8,
‘content’=>’mypost=’.$post_string)
);
$stream_context = stream_context_create($context);
$data = file_get_contents($remote_server,FALSE,$stream_context);
return $data;
}
?>
