PHP: define functions with variable names

Question

I have an array of strings and I want to define functions with names being these strings. Is there a way to do that in PHP?

$a = array("xxx", "yyy", "zzz");

How do I programmatically define xxx(), yyy(), and zzz()?

Many thanks

If you really had to you could declare the function within an eval block:

foreach ($a as $functionname)
eval('
        function '.$functionname.' () {
            print 123;
        }
');

But that incurs some extra parsing time speed penalty over just declaring the functions in a file.
