How do I see the extensions loaded by PHP?
提问by Bialecki
It's got to be somewhere in the phpinfo() dump, but I just don't know where. Is it supposed to be under the "Additional Modules" section? Somewhere else? I'm trying to figure out why some extensions don't appear to be loaded, but I don't even know where I should be looking.
它必须在 phpinfo() 转储中的某个地方，但我只是不知道在哪里。它应该在“附加模块”部分下吗？别的地方？我想弄清楚为什么有些扩展似乎没有加载，但我什至不知道我应该去哪里找。

Run command. You will get installed extentions:

Are you looking for a particular extension? In your phpinfo();, just hit Ctrl+Fin your web browser, type in the first 3-4 letters of the extension you're looking for, and it should show you whether or not its loaded.
您在寻找特定的扩展名吗？在您的phpinfo();，只需在您的网络浏览器中点击Ctrl+ F，输入您正在寻找的扩展程序的前 3-4 个字母，它应该会显示它是否已加载。
Usually in phpinfo()it doesn't show you all the loaded extensions in one location, it has got a separate section for each loaded extension where it shows all of its variables, file paths, etc, so if there is no section for your extension name it probably means it isn't loaded.
通常phpinfo()它不会在一个位置显示所有加载的扩展，它为每个加载的扩展都有一个单独的部分，它显示了它的所有变量、文件路径等，所以如果你的扩展名没有部分可能意味着它没有加载。
Alternatively you can open your php.ini file and use the Ctrl+Fmethod to find your extension, and see if its been commented out (usually by a semicolon near the start of the line).
或者，您可以打开 php.ini 文件并使用Ctrl+F方法查找您的扩展名，并查看它是否已被注释掉（通常在行开头附近用分号）。
