如何看到PHP加载的扩展?

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()转储文件的某个地方，但是我不知道在哪里。它应该在“附加模块”部分下吗?别的地方吗?我试图弄明白为什么有些扩展没有加载，但我甚至不知道应该在哪里查找。

Are you looking for a particular extension? In your phpinfo();, just hit Ctrl+F in 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.

你在找特别的分机吗?在phpinfo()中，在web浏览器中按下Ctrl+F，输入要查找的扩展名的前3-4个字母，它应该显示它是否加载了。

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.

通常在phpinfo()中，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，它显示了所有的变量、文件路径等，所以如果没有为您的扩展名提供部分，它可能意味着它没有加载。

Alternatively you can open your php.ini file and use the Ctrl+F method to find your extension, and see if its been commented out (usually by a semicolon near the start of the line).

也可以打开php。ini文件和使用Ctrl+F方法找到你的扩展名，看看它是否被注释掉了(通常在行开头用分号)。
