How do I see the extensions loaded by PHP?

Question

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.

Answer 1

Running

php -m

will give you all the modules, and

php -i

will give you a lot more detailed information on what the current configuration.

Answer 2

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.

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.

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).
