Description:
------------
I'd like to have a fast function, which concatenates a string to each element of an array.

Reproduce code:
---------------
array array_concatenate ( array array, string string [, bool to_end=true])

Something like this as a php function:

$arr=array(1,2,3,4,5,6,7,8,9,0);
$str=' test';

array_walk($arr,create_function('&$elem','$elem .= "' . $str . '";'));


Expected result:
----------------
array ( 0 => '1 test', 1 => '2 test', 2 => '3 test', 3 => '4 test', 4 => '5 test', 5 => '6 test', 6 => '7 test', 7 => '8 test', 8 => '9 test', 9 => '0 test', )

Actual result:
--------------
;-)
