Re: PHP 4.0 Bug #4875: array_merge() is unable to merge arrays with numeric keys

1) Automatic conversion: Agreeing. It should really be possible to choose array indices which will not be converted to an integer if they consist of numbers only. If I choose $array=array('0'=>'foo',0=>'foo2'); I would like to have an array with two key/values pairs. 2) Array_Merge() It would help if array_merge() remembers numeric indices. $array=array(0=>'foo',5=>'boo',9=>'zoo'); $array2=array(4=>'loo',7=>'noo'); $res_array=array_merge($array,$array2); should result in $res_array(0=>'foo',5=>'boo',9=>'zoo',4=>'loo',7=>'noo'); An additional function could merge arrays loosing their numeric indices, eg. array_flat_merge()... regards wrote:

Bug description:  array_merge() is unable to merge arrays with numeric keys 

array_merge() is unable to merge arrays with numeric keys (as described in the documentation), however that´s usefull sometimes and should be possible, in face of the fact that even casting the keys to (string) they´re saved as (int)s.

Please describe in more detail how you want arrays with numeric keys to be merged. Here's an example: $a = array("a"=>"a"); $b = array("1"=>"b"); $c = array_merge($a, $b); while(list($k,$v)=each($c)) echo "$k:$v\n"; gives a:a 0:b but would be nice if got a:a 1:b when 1 is a string. The problem is not with array_merge, but with arrays in general I think. It seems that a numeric string like "1" is treated as an index and not a key. Would be nice if there was a difference, but fixing it might break a lot of existing PHP code I guess.
