foreach loops, PhpStorm will suggest a suitable variable name for
the array item based on the name of the array. So if your array is called
$items PhpStorm will suggest
$item, the singular form of items.
PhpStorm is even smart enough to work out the singular form of words like people, octopi and oxen; I have yet to catch it out.
You can use this feature in custom live templates by incorporating the
phpSuggestVariableName expression function in your live template variables.
