Thank you for your bug report. This issue has already been fixed in the latest released version of PHP, which you can download at http://www.php.net/downloads.php "As of PHP 4.3.0, the index generation behaviour described above has changed. Now, if you append to an array in which the current maximum key is negative, then the next key created will be zero (0). Before, the new index would have been set to the largest existing key + 1, the same as positive indices are." Previous Comments: ------------------------------------------------------------------------ [2003-08-04 16:03:15] [EMAIL PROTECTED] This is a documentation issue. The change was made to avoid possible crashes. ------------------------------------------------------------------------ [2003-08-03 19:40:43] [EMAIL PROTECTED] This behaviour was introduced in 4.3.0 - reclassifying as an array problem. I don't know if the behaviour or the documentation should be changed. ------------------------------------------------------------------------ [2003-06-12 15:38:20] rsen010 at ec dot auckland dot ac dot nz Description: ------------ Hi, When I was going through “Chapter 7.types” in PHP manual I found something confusing regarding the following statement “Having e.g. the highest index being -6 will result in -5 being the new key” (under Syntax – specifying with array()).What actually happens is it Php starts indexing from zero if lowest index is negative value unless there is no index of zero. But amazing thing is sometimes it omit some values unless. Just consider the following examples. Ex:1 $a = array(-3=>'February', 'March'); print_r($a); This will prints out the folloiwng > Array ( [-3] => February [0] => March ) Ex:2 $a = array( 'January', '0'=>'a','b', 'c',-3=>'February', 'March'); print_r($a); This will prints out the folloiwng Array ( [0] => a [1] => b [2] => c [-3] => February [3] => March ) Please be kind to check this out if I’m correct and reply me. Thanks Naleen Reproduce code: --------------- $a = array(-3=>'February', 'March'); print_r($a); $a = array( 'January', '0'=>'a','b', 'c',-3=>'February', 'March'); print_r($a); Expected result: ---------------- Array (-3=>February, [-2] => March ); Array ( [1]=>January [0] => a [2] => b [3] => c [-3] => February [4] => March ) Actual result: -------------- Array ([-3] => February [0] => March ) Array ( [0] => a [1] => b [2] => c [-3] => February [3] => March ) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=24159&edit=1
