我试图得到谷歌简单查询的例子(离开GitHub)工作，不幸的是，一个明确缺乏成功…我得到的是一个255的退出码。
我确定问题出在对Google Server的调用中，所以在代码中添加了一个异常处理程序。程序现在看起来像这样:

如有任何帮助，不胜感激。
注意:这可能只是一个身份验证问题。我是一个远程工作者，无法访问谷歌控制台，所以必须依靠老板发誓他已经提供了正确的密钥!
我实际上是GitHub上的rowanrh。在上面发布之后-没有收到任何帮助-我决定在GitHub上复制这篇文章。
我刚刚通过更改以下PHP.ini设置解决了这个问题:
- 我设置(通过取消注释)扩展名=php_openssl.dll -需要'https' url;和 我设置了时区。谷歌对时间很挑剔，所以这可能影响了结果。
