I have set up code inspection for php doc blocks, so now I will get warning if they are missing or incomplete.
When I have one class open, I can use
Code > Generate > PhpDocBlocks
In the project overview, you can right click a folder and select
Inspect Code. It's also available via
Code > Inspect Code.
A window will pop up asking you for further detail and you also can expect the scope to whole context.
Make sure your Inspection Profile contains PHPDoc. If the inspection has run through, you then will have a PHPDoc section,
By right clicking you then can
Apply Fix even for multiple classes.
