Bug #77699 [NEW]: Switch statement in foreach loop incorrect comparisons

From: eguthrie3214 at gmail dot com Operating system: All PHP version: Irrelevant Package: Arrays related Bug Type: Bug Bug description:Switch statement in foreach loop incorrect comparisons Description: ------------ When using a switch statement inside a foreach loop array elements that have a value of 0 are compared in case statements incorrectly. Test script: --------------- $a = [0,0,0,0,0]; foreach ($a as $i) { switch ($i) { case $i > 0: echo 'true'; } } Expected result: ---------------- We should expect no output since 0 is not greater than 0 and therefore doesn't satisfy the case. This has been tested on both 7.2 and 7.1.
