$flag = TRUE; // this variable is hinted as unused
$prefix = 'sushi_'; // this variable is also hinted as unused

require './makepage.php';

/** makepage.php **/

if($flag) { /* stuff */ }
$dish = $prefix.$name;

It would be awesome if the Hint could catch that---there would be a lot fewer "false hints", which would make the hint more useful. As it is, the hints can be so many that I don't look at them anymore.

One way to implement might be to add a flag in Options / Editor / Hints / Unused Variables to "Check Included Files".

Thanks team, wishing you a beautiful week.
