Unable to find correct PHP plugin

I just installed IntelliJ IDEA Ultimate (free 30-day trial) because it said it had web tools, but I'm not finding PHP in there (seems to be the only one not there), so I read that I'm supposed to install the plugin (which says it's only for Ultimate users, which I have of course), but when I search for 'php' in plugins (even in Browse), it either shows nothing or hundreds of results, and if I filter by Languages, it shows various PHP plugins which are different than the one here:

https://plugins.jetbrains.com/plugin/9662-php-latest

I'm coming from PHPStorm and my company won't get a license for it, but does have licenses for IntelliJ, so I need to know how to get PHP working as expected in it before I request a license.
