See bug #29008 which fixed the behaviour from ignoring all other types
but integers. Now it just does convert_to_string() on any other than
integer. This is a bit tricky. IMO the current behaviour of
array_combine() is expected and should stay. It might be "unexpected"
but perhaps just documenting it as such would be sufficient. (I happen
to rely on this function to behave like this so changing it would make
me a sad puppy :)

Ilia, what do you think?

If you look closely at the var_dump() output you'll notice that they're
not floats but strings. This is expected and correct behaviour.

Description:
------------
when array with float values is passed to $keys argument of 
array_combine()function, it creates an array with float keys and the
values specified by $values argument. This is in contradiction with the
array documentation, which specifies that only integers or strings can
be used as keys in an array.Same can be found in the below link.

http://in2.php.net/manual/en/language.types.array.php

So, either of the below is expected:

1) An error message saying that float values can't be used as keys for 
an array should be output or 
2) float keys should be truncated to integer keys.

This behaviour can be found with PHP5.3 and PHP6 as well.


Reproduce code:
---------------
<?php
$arr1 = array(1.1, 2.2);
$arr2 = array(1, 2);
var_dump( array_combine($arr1, $arr2) );
?>


Expected result:
----------------
array(2) {
  [1]=>
  int(1)
  [2]=>
  int(2)
}



Actual result:
--------------
array(2) {
  ["1.1"]=>
  int(1)
  ["2.2"]=>
  int(2)
}
