Actually there is a way to do this but I am sure how appropriate it is.
Here is a simple of example of the concept. It does what I want but not
convinced this is the best way to do it. If it is then I could simply place
a list of strings in an array and index them with an input string.
<?php
class A
{
function A()
{
print("creating A");
}
}
$a = "A";
new $a."()";
?>
Thanks mike
