我有一个页面，它接受用户输入的字符串并将其用作许多搜索 API 的查询字符串。我的问题是我自己的 Google+ API 可以正常工作。我还可以让 YouTube 数据 API 自行运行。但是，当我将代码放在同一页面上时，两者都会中断。
我已将问题缩小到如果我 include() 或 require() google-api-php-client/src/contrib/ 目录中的任何其他 .php 文件，Google_PlusService.php 无法处理它。
如果我 include() 或 require() 任何其他 .php 文件，Google_YouTubeService.php 可以很好地应对。Google_PlusService.php 不能。
即使我不使用这些其他 API，只使用 include() 或 require()，它仍然会中断。
我正处于精神错乱的边缘，因此非常欢迎任何帮助。

更多信息：即使我删除了除了 require_once() 语句之外的所有内容，这将起作用：
function youtubeandgoogleplusSearch($searchstring) {
require_once("google-api-php-client/src/Google_Client.php");
require_once("google-api-php-client/src/contrib/Google_PlusService.php");
//require_once("google-api-php-client/src/contrib/Google_YouTubeService.php");
echo 'JUST TESTING';
}
这不会：
function youtubeandgoogleplusSearch($searchstring) {
require_once("google-api-php-client/src/Google_Client.php");
require_once("google-api-php-client/src/contrib/Google_PlusService.php");
require_once("google-api-php-client/src/contrib/Google_YouTubeService.php");
echo 'JUST TESTING';
}
