Browser 从命令行运行但不在浏览器中的PHP脚本

我正在尝试获取Google Adwords API，其中有一个示例目录可以从命令行正常运行，但当我在浏览器中打开时，它无法正常工作，它只显示：

错误324（net:：ERR_EMPTY_RESPONSE）：服务器关闭了连接，但未发送任何数据

以下是完整的代码：

嗯，这看起来很合理。调试PHP可能是一件痛苦的事情，通常没有什么比添加

echo

s或

error\u log

s的负载并在代码中平分找到导致问题的行更好的方法。在顶部敲入一个回音，以确保它被正确解析，以此类推。问题要么在代码中，要么在配置中，您可能不得不进行一些修补，直到您可以从中获得更多的输出。

脚本可能执行它应该执行的任何操作，但根本不发送任何数据？粗略地看一下源代码，有可能只在cli中打印printf，而不在浏览器中打印？@Pete-nope，printf总是输出，但可能会出现从未触发的情况。尝试无条件的

回显“OK”

以查看发生了什么；除非我注释掉$page=$targetingdiaservice->get（$selector），否则不会打印@Pete在这种情况下，PHP很可能会崩溃并显示错误消息。也许

display\u errors

没有打开？嗯，谢谢你的建议，我发现这一行是问题的原因（从注释每一件事和使用backwords:$page=$targetingdiaservice->get（$selector）有API的文档吗？

$selector

的值看起来像应该传入的字符串吗？你能在调用后打印

$page

的值吗？等等？我实际上刚刚试过，我打印了它，然后注释掉了整个if/else，当我在浏览器中输入时，它仍然不能打印如果要在cli中再次运行它，它实际上会打印出包含adwords沙盒中多个关键字的整个响应，$selector在浏览器和cli中的显示完全相同。它使用“auth.ini”文件为其提供凭据，这会产生影响吗？
