Bug description: array_combine skips keys of type other than int or string
Description:
------------
The array_combine function skips keys of type other than int or string
while operator [] allows one to add also other types (like null,boolean,
float). Note, that array_combine converts string keys in exactly the same
way as the operator [] does (i.e. "10" -> 10 etc.).
IMHO array_combine should not skip keys with other types than string or
int but convert them to a string or an int.
Thus array_combine should behave like [] operator.
Moreover, the PHP_Compat package does it so but there is another bug
there: if illegal key is found (e.g. an array) a warning is reported
instead of skipping such key (@ is missing there).
Reproduce code:
---------------
$a = array("0",0,"-10",-10,null,5.4,array(1,2,3),false);
$b = array(1,2,3,4,5,6,7,8);
var_dump(array_combine($a,$b));
Expected result:
----------------
array(4) {
[0]=>
int(8)
[-10]=>
int(4)
[""]=>
int(5)
[5]=>
int(6)
}
Actual result:
--------------
array(2) {
[0]=>
int(2)
[-10]=>
int(4)
}
