#44444 [NEW]: Error in array_unique when objects are values

From: pawel dot jacek dot matysiak at gmail dot com Operating system: Windows XP PHP version: 5.2.5 PHP Bug Type: Arrays related Bug description: Error in array_unique when objects are values Description: ------------ I've encountered a problem when working with array of objects and using mentioned library function array_unique. It just doesn't work. Reproduce code: --------------- <?php class Test { public $x; public function __construct($x) { $this->x = $x; } } $temp[] = new Test(1); $temp[] = new Test(1); var_dump($temp); $temp2 = array_unique($temp); var_dump($temp2); ?> Expected result: ---------------- I expected the function to return the array with only one object. It could return unchanged array but I think it would not make any sense. Actual result: -------------- error: Catchable fatal error: Object of class Test could not be converted to string in test.php on line 13 -- Edit bug report at http://bugs.php.net/?id=44444&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=44444&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=44444&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=44444&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=44444&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=44444&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=44444&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=44444&r=needscript Try newer version: http://bugs.php.net/fix.php?id=44444&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=44444&r=support Expected behavior: http://bugs.php.net/fix.php?id=44444&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=44444&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=44444&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=44444&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=44444&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=44444&r=dst IIS Stability: http://bugs.php.net/fix.php?id=44444&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=44444&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=44444&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=44444&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=44444&r=mysqlcfg
