It's really hard and performance consuming to implement this behavior. But: 1) $a in fileB is NOT hinted as "unsued" because it IS used (in assignment with $b), so everything is ok. 2) ...here is no $a so it can't be hinted ;) but $c is hinted, because we can't really go through included files...as I wrote, it's really performance consuming... ...so it's really feature. Enhancement is a correct issue type :) Thanks for your cooperation! |
Product Version = NetBeans IDE 7.1 (Build 201112071828) Operating System = Linux version 3.0.0-14-generic-pae running on i386 Java; VM; Vendor = 1.6.0_23 Runtime = OpenJDK Client VM 20.0-b11 Not sure if this is intended behavior. If it is then this is a feature request. Also hints unused in the included file but that's probably a lot harder ! Case 1: File included before ======================== fileA <?php $a=0; ?> fileB <?php include('FileA'); $b = $a; // <==== $a NOT hinted unused ?> Case 2: File included after ====================== fileC <?php $d = $c; ?> fileD <?php $c = 0; // <==== $a IS hinted unused include('FileC); ?>
