From: Operating system: Gentoo Linux PHP version: 5.4.4RC1 Package: Scripting Engine problem Bug Type: Bug Bug description:New behavior of string == has a compatibility problem
Description: ------------ The behavior of string comparison using == operator is changed in https://github.com/php/php-src/commit/47db8a9aa19f6e17a1018becf9978315c79a1cb0 to fix bug #54547. This change has a compatibility problem. Before this change (PHP 5.4.3), "01234" == "1234" => TRUE (OK) "09223372036854775808" == "9223372036854775808" => TRUE (compared as float, but result is acceptable) After change, "01234" == "1234" => TRUE (OK) "09223372036854775808" == "9223372036854775808" => FALSE (compared as string) This behavior is not reasonable in that case. New rule is not clear. I think this change should be reverted, before release of 5.4.4. Test script: --------------- echo (("01234" == "1234") ? "true" : "false"), "\n"; echo (("09223372036854775808" == "9223372036854775808") ? "true" : "false"), "\n"; Expected result: ---------------- true true Actual result: -------------- true false -- Edit bug report at https://bugs.php.net/bug.php?id=62097&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=62097&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=62097&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=62097&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=62097&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=62097&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=62097&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=62097&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=62097&r=needscript Try newer version: https://bugs.php.net/fix.php?id=62097&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=62097&r=support Expected behavior: https://bugs.php.net/fix.php?id=62097&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=62097&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=62097&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=62097&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=62097&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=62097&r=dst IIS Stability: https://bugs.php.net/fix.php?id=62097&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=62097&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=62097&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=62097&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=62097&r=mysqlcfg
