Summary

On the following line the imageUrl() docblock is telling me that there are only 6 parameters, see here:

But the method itself uses 7, as stated here:

Therefore PHPStorm or any other IDE will show the wrong autocomplete / hints.

Solution:

@method string imageUrl($width = 640, $height = 480, $category = null, $randomize = true, $word = null, $gray = false, $format = 'png')
