【问题描述】：
我有一个运行 php7.0（Apache 2.0 处理程序）和 php7.2（FPM/FastCGI）的 apache2 的 ubuntu 服务器（16.04.4 LTS）。
PHP7.2 工作正常，除了没有加载扩展 - 比如 json 或其他任何东西。看我的 phpinfo():

我猜问题是，没有额外的 .ini 文件被解析。但是 phpinfo 说它会扫描目录 /etc/php/7.2/fpm/conf.d 以获取其他 .ini 文件。 这是目录列表：

我已经重启了apache2服务器，但没有任何效果。
如何告诉我的 php-fpm 使用这些扩展？
【问题讨论】：
-
你检查你的 php.ini 了吗？
-
是的，当然。为了测试，我取消了一些扩展的注释，重新启动了apache2，没有效果...
-
您可能从其他目录中删除了包含其他文件的代码行：
-
好的，@Kerel，那行存储在哪里？
