Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php The slight BC breakage is negligible compared to the benefits of getting it to work properly. Previous Comments: ------------------------------------------------------------------------ [2009-02-13 01:53:09] for-bugs at hnw dot jp Thank you so much. The snapshot returns same result to PHP 5.2.8 with reproduce code. Such as: array(2) { [0]=> int(0) [1]=> string(0) "" } array(2) { [0]=> string(0) "" [1]=> string(1) "0" } ------------------------------------------------------------------------ [2009-02-12 18:58:34] moriyo...@php.net Please try using this CVS snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows: http://windows.php.net/snapshots/ ------------------------------------------------------------------------ [2009-02-12 18:12:35] moriyo...@php.net Verified with 5.2, 5.3, HEAD. ------------------------------------------------------------------------ [2009-02-12 16:25:59] for-bugs at hnw dot jp Sorry, reproduce code was incorrect. Correct code is below: <?php var_dump(array_unique(array(0,"","0"))); var_dump(array_unique(array("","0",0))); ------------------------------------------------------------------------ [2009-02-12 16:22:38] for-bugs at hnw dot jp Description: ------------ In PHP5.2.9RC1, array_unique() returns different result because of element ordering in array. Reproduce code shows this difference. It is because SORT_REGULAR never cast array elements and compares them with ==. I think it's better for SORT_REGULAR to compare elements by using === instead of ==. PHP 5.2.9RC1's array_unique() also has backward compatibility ploblem. Considering backward compatibility, default sort_flag should be SORT_STRING. Reproduce code: --------------- <?php var_dump(arary_unique(array(0,"","0")))); var_dump(arary_unique(array("","0",0)))); Expected result: ---------------- I don't know, but 2 results should be same. Actual result: -------------- array(1) { [0]=> int(0) } array(2) { [0]=> string(0) "" [1]=> string(1) "0" } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=47370&edit=1
