PHP dump $_REQUEST to file
提问by Jamie Redmond
I want to dump request variables to a file for debugging. How's this possible?
我想将请求变量转储到文件中进行调试。这怎么可能？

<?php
$req_dump = print_r($_REQUEST, TRUE);
$fp = fopen('request.log', 'a');
fwrite($fp, $req_dump);
fclose($fp);
Untested but should do the job, just change request.log to the file you want to write to.
未经测试但应该可以完成这项工作，只需将 request.log 更改为您要写入的文件。

I think nowadays this method is easier and faster:
我认为现在这种方法更容易和更快：
$req_dump = print_r($_REQUEST, true);
$fp = file_put_contents('request.log', $req_dump, FILE_APPEND);

Use serialize()function for dumping. Dump $_SERVER, $_COOKIE, $_POSTand $_GETseparately (may go to the same file). If you're planning on debugging with the data it helps to know if the data was part of a POST request or a GET request.
使用serialize()功能进行倾销。转储$_SERVER，$_COOKIE，$_POST和$_GET分别（可以去到同一文件）。如果您计划对数据进行调试，那么了解数据是 POST 请求还是 GET 请求的一部分会很有帮助。
Dumping everything is good for debugging in development, but not so in production. If your application does not have many users, it can work in production too. If you anticipate many users, consider dumping just the $_POSTdata, or limit server variables to those starting with HTTP_.
转储一切有利于开发中的调试，但在生产中则不然。如果您的应用程序没有很多用户，它也可以在生产中工作。如果您预计会有很多用户，请考虑仅转储$_POST数据，或将服务器变量限制为以 HTTP_ 开头的变量。
