Bug #70669 [Opn->Nab]: Strings starting with a '+' == 0

Edit report at https://bugs.php.net/bug.php?id=70669&edit=1 ID: 70669 Updated by: nikic@php.net Reported by: wayne at huntedcow dot com Summary: Strings starting with a '+' == 0 -Status: Open +Status: Not a bug Type: Bug Package: Scripting Engine problem Operating System: any PHP Version: 5.6.14 Block user comment: N Private report: N New Comment: This has nothing to do with '+'. In general 0 == "not-numeric-string" always holds. Essentially comparison of integer to string works by casting the string to an integer first.

This resulted in my if ($value == '+TIMESTAMP') coming out true, when $value = 0. Test script: --------------- echo (0 == '+' ? 'TRUE' : 'FALSE'); Expected result: ---------------- FALSE Actual result: -------------- TRUE ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=70669&edit=1
