捕获php请求内容

通过将phpinfo()打印到文件实现

<?php

echo str_pad('', 1024);//使缓冲区溢出
ob_start();//打开缓冲区
phpinfo();
$string = ob_get_contents();//获取缓冲区内容

$myfile = fopen("phpinfo.html", "w") or die("Unable to open file!");
fwrite($myfile, $string);
fclose($myfile);

ob_end_clean();//清空并关闭缓冲区
?>

获取CURLOPT_POSTFIELD的内容 用file_get_contents("php://input")

<?php

$myfile = fopen('upload_files/'.$_REQUEST['file_id'], "w") or die("Unable to open file!");
fwrite($myfile, file_get_contents("php://input"));
fclose($myfile);

?>
