A better approach than those suggested if you have a large array of information would be to make use of the splice function - This allows you to change an array element, O(1) execution, in place without iterating over the entire array, O(n) execution. For example:

my @array = ( 'foo', 'moo', 'baz' );

splice @array, 1, 1, 'bar';

The downside to this approach is that you will need to know the array position of the string which you are looking at modifying. If you do not know this index, then you would be better off exploring a loop or map construct as suggested and depending upon your requirements - Also of interest might be this node.
