PHP脚本从命令行运行，但没有在浏览器中运行

Question

我试图获得Google Adwords API，并且开箱即用，有一个示例目录可以从命令行正常运行，但当我离开时它不能正常运行在浏览器中它只是读取：

错误324（net :: ERR_EMPTY_RESPONSE）：服务器关闭连接而不发送任何数据。

下面是全部代码：

我能做些什么来解决这个问题呢？

谢谢！

那么，它看起来很明智。调试PHP可能是一件痛苦的事情，通常没有什么比做更好的事情要做的事情要比添加一个echo s或error_log s的负载，并且通过代码找到导致问题的线路。在顶部重复一遍以确保正确解析，等等。这个问题要么在代码中，要么在配置中，你可能不得不自己去纠缠一些，直到你能从中获得更多的输出。
