Bug #71262 [Com]: for loop error

Edit report at https://bugs.php.net/bug.php?id=71262&edit=1 ID: 71262 Comment by: php at duncanc dot co dot uk Reported by: m dot dziczkowski at prokonto dot pl Summary: for loop error Status: Not a bug Type: Bug Package: Scripting Engine problem Operating System: Linux PHP Version: 5.6.4 Block user comment: N Private report: N New Comment: Your example is flawed, the second "not working" loop will not loop because $y is never "less than or equal to" 1945, it starts off at 2015. I think you meant to do: for ($y = 2015; $y >= 1945; $y--) { // some code to do } Previous Comments: ------------------------------------------------------------------------ [2016-01-02 07:06:32] requinix@php.net > for ($y = 2015; $y <= 1945; $y--) $y starts at 2015. 2015 <= 1945 is false. Loop exits immediately.

Increasing value is working, but decreasing isn't. See code Test script: --------------- // Working for ($y = 1945; $y <= 2015; $y++) { // some code to do } // Not working for ($y = 2015; $y <= 1945; $y--) { // some code to do } // sames happens if I replace (in the not working one) the "2015" with a variable (for example: $year = 2015; or $year = date("Y"); Expected result: ---------------- displayed values from 2015 to 1945 Actual result: -------------- none ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71262&edit=1
