PHP腳本從命令行運行但不在瀏覽器中運行

Question

我正在嘗試使用Google Adwords API，並且開箱即用，有一個示例目錄可以從命令行運行正常，但是當我在瀏覽器中看到它時，它無法正常工作：

錯誤324（net :: ERR_EMPTY_RESPONSE）：服務器關閉連接而不發送任何數據。

以下是完整的代碼：

<?php

我該怎么做才能解決這個問題？

謝謝！

嗯，看起來很合理。 調試PHP可能會很麻煩，而且通常沒有什么比添加一個echo s或error_log更好的了，並且通過代碼將您的方法分成兩部分來查找導致問題的行。 在頂部回聲，確保它被正確解析，等等。 問題出在代碼或配置中，你可能不得不讓自己屈服於一些修補，直到你可以從它獲得更多的輸出。
