Changing values of associative arrays

[redneck]

I am looking for a construct which loop through an associative array and change the values of each of the array elements.

For example, for each element in an array I want to append some text to the value. A code example might look like this:

    foreach ($link_array as $link_string) {
      $link_string = "<a href=\"$link_string\" target=\"$link_string\">";
    }

Obviously, this doesn't work because the assignment is to the placeholder var $link_string, not to the actual value of the array.

Since I know the keys, as a last resort I could simply make assignments using subscripts, but I should think there was a way to loop through and do it without knowing the keys.

while( list($key,$value) = each ($your_array))
{
  $your_array[$key] = $value."something_to_add";
}
reset($your_array);
