What is your use case? Previous Comments: ------------------------------------------------------------------------ [2017-10-06 17:40:16] langebroek at gmail dot com Description: ------------ Rather self explanatory; it seems impossible to have a numeric string as an array key. For the project I'm working on this is almost a necessity. Test script: --------------- $buf=array((string)1=>'x',"2"=>'y','3'=>'z'); #var_dump($buf);//all int var_dump(array_keys($buf));//clarify all int Expected result: ---------------- In at least one case I'd expect to see a string in the array key, or have an alternative method to achieve such. In some cases it is unwise to typecast at a later time. Actual result: -------------- array(3) { [0]=> int(1) [1]=> int(2) [2]=> int(3) } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75328&edit=1
