Bug #67947 [Nab]: array_keys case-insensitive compare not work even if bool $strict false

Edit report at https://bugs.php.net/bug.php?id=67947&edit=1 ID: 67947 User updated by: rob_neal at rocketmail dot com Reported by: rob_neal at rocketmail dot com Summary: array_keys case-insensitive compare not work even if bool $strict false Status: Not a bug Type: Bug Package: Arrays related Operating System: Windows 8.1 PHP Version: 5.5.16 Block user comment: N Private report: N New Comment: Thank you for your reply. I now see that this is not a bug. In your reply you shared some useful information: "$strict has nothing to do with case sensitivity". Though the php docs need to be concise, it would be useful/helpful to add a short statement like that on all "strict" arguments for all functions with a link to learn more about exactly what "strict comparisons" mean and how it does not mean consideration of case-sensitivity.

This is latest version of XAMPP/PHP as of today's date. Only changes to default php.ini that I have made are about Mail and XDebug for debugging with Komodo IDE. Test script: --------------- $arr = array('uuu', 'abc','aBC','ABC','abc', 'Def', 'DEF', 'xyz'); //set 3rd argument as $strict=false for case-insensitive $k = array_keys($arr,'abc',false); print_r($k); Expected result: ---------------- Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 ) Actual result: -------------- Array ( [0] => 1 [1] => 4 ) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=67947&edit=1
