PHP脚本从命令行运行但不在浏览器中运行

Question

I am trying to get the Google Adwords API, and right out of the box there's an example directory that runs fine from the command line but it doesn't work properly when I go to in the browser it just reads:

Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data.

Here is the code in its entirety:

<?php
/**

What can I do to troubleshoot this problem?

Thanks!

Well, it looks sensible. Debugging PHP can be a pain, and there's often nothing better to do than add a load of echo s or error_log s and bisect your way through the code to find the line that's causing the problem. Whack in an echo at the top to make sure it's being parsed properly, and so on. The problem's either in the code, or the configuration, and you might have to resign yourself to some tinkering until you can get some more output from it.
