PHP将$ _REQUEST转储到文件中

Question

我想将请求变量转储到文件进行调试.这怎么可能？

Answer 1

<?php
$req_dump = print_r($_REQUEST, TRUE);
$fp = fopen('request.log', 'a');
fwrite($fp, $req_dump);
fclose($fp);

未经测试但应该完成这项工作,只需将request.log更改为您要写入的文件即可.

Answer 2

我认为现在这种方法更简单,更快捷:

$req_dump = print_r($_REQUEST, true);
$fp = file_put_contents('request.log', $req_dump, FILE_APPEND);

Answer 3

使用serialize()转储功能.转储$_SERVER,$_COOKIE,$_POST和$_GET分别(可以去到同一文件).如果您计划使用数据进行调试,则有助于了解数据是POST请求还是GET请求的一部分.

倾倒一切对于开发中的调试很有用,但在生产中则不然.如果您的应用程序没有很多用户,它也可以在生产中使用.如果您预计有许多用户,请考虑仅转储$_POST数据,或将服务器变量限制为以HTTP_开头的服务器变量.
