Bug #71954 [NEW]: array_unique and datetimes

From: marcelloh at gmail dot com Operating system: win10 PHP version: 7.0.5 Package: *General Issues Bug Type: Bug Bug description:array_unique and datetimes Description: ------------ I have this array filled with all kinds of types. Today I used a DateTime object in that array for the first time. In my code there is this line: $aUniqueValues = array_unique($aValues); and there is an fatal error now: Catchable fatal error: Object of class DateTime could not be converted to string in MyClass.php on line 149 I can't find in the documentation http://php.net/manual/en/function.array-unique.php how to catch that error. Test script: --------------- $aValues = array(); $now = date('Y-m-d H:i:s'); $aValues['test1'] = $now; $aValues['test2'] = DateTime::createFromFormat('Y-m-d H:i:s', $now); $aUniqueValues = array_unique($aValues); Expected result: ---------------- I would expect no fatal error, but a normal unique array. I think, it is a bit strange that I can make a string out of a DateTime object, and that the code behind array_unique can't do that. -- Edit bug report at https://bugs.php.net/bug.php?id=71954&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=71954&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=71954&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=71954&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=71954&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=71954&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=71954&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=71954&r=needscript Try newer version: https://bugs.php.net/fix.php?id=71954&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=71954&r=support Expected behavior: https://bugs.php.net/fix.php?id=71954&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=71954&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=71954&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=71954&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=71954&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=71954&r=dst IIS Stability: https://bugs.php.net/fix.php?id=71954&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=71954&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=71954&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=71954&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=71954&r=mysqlcfg
