php的http数据传输get/post...

一般有：file_get_contents,curl,fsockopen....

下面介绍fsockopen:

//构造要post的字符串       $argv = $_POST;        $data = http_build_query($argv);        $length = strlen($data);        //创建socket连接        $fp = fsockopen("order.com",80,$errno,$errstr,10) or exit($errstr."--->".$errno);        //构造post请求的头        $header = "POST /pay/sub HTTP/1.1\r\n";        $header .= "Host:order.com\r\n";        $header .= "Content-Type: application/x-www-form-urlencoded\r\n";        $header .= "Content-Length: ".$length."\r\n";        $header .= "Connection: Close\r\n\r\n";        //添加post的字符串        $header .= $data."\r\n";        //发送post的数据        fputs($fp,$header);        $inheader = 1;        while (!feof($fp)) {            $line = fgets($fp,10240); //去除请求包的头只显示页面的返回数据            if ($inheader && ($line == "\n" || $line == "\r\n")) {                $inheader = 0;            }            if ($inheader == 0) {                //echo $line;            }        }        echo $line;        exit;
