Bug #66286 [NEW]: Comparing objects - very strange behaviour

From: m dot straczkowski at gmail dot com Operating system: Linux Ubuntu PHP version: 5.5.7 Package: Class/Object related Bug Type: Bug Bug description:Comparing objects - very strange behaviour Description: ------------ Hello, There is a problem with object comparing. I can't see any logical reason for this to happen. While comparing two different objects (with == operator) PHP returns true once and after var_dump / print_r (on objects) it returns false. As PHP Manual said: "Two object instances are equal if they have the same attributes and values, and are instances of the same class." Our example two objects are not equal because their attribute values are different. Script which shows this strange behaviour: http://pastebin.com/nwEbe7sc I'm using PHP 5.5.7-1+sury.org~saucy+1 Problem occurred on previous versions too Test script: --------------- http://pastebin.com/nwEbe7sc Expected result: ---------------- bool(false) B Object ( [errors:protected] => Array ( ) [value:protected] => ABC ) B Object ( [errors:protected] => Array ( ) [value:protected] => CBA ) bool(false) Actual result: -------------- bool(true) B Object ( [errors:protected] => Array ( ) [value:protected] => ABC ) B Object ( [errors:protected] => Array ( ) [value:protected] => CBA ) bool(false) -- Edit bug report at https://bugs.php.net/bug.php?id=66286&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=66286&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=66286&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=66286&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=66286&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=66286&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=66286&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=66286&r=needscript Try newer version: https://bugs.php.net/fix.php?id=66286&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=66286&r=support Expected behavior: https://bugs.php.net/fix.php?id=66286&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=66286&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=66286&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=66286&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=66286&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=66286&r=dst IIS Stability: https://bugs.php.net/fix.php?id=66286&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=66286&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=66286&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=66286&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=66286&r=mysqlcfg
