How to enable php documentation in phpstorm?

Question

phpstorm

I saw the recently built-in or as a plugin php documentation in phpstorme.

Already half the Internet rummaged, but did not find how to install. Maybe I dug in the wrong direction.
In short, I want one.
Thanks in advance for your help.

Answer 1

It comes with phpstorm by default. Hold ctrl and click LMB on the name (call) of the built-in function / method / class, etc. phpstorm will open the documentation for this element.

echo strlen('example'); // Щелкаем ЛКМ с зажатым ctrl по strlen и попадаем на страницу с информацией о данной функции.
