Im sure I have seen an implementation of this in PHP somewhere and I am positive if it exists its a PHP 5 thing. Any way I was wondering if it was possible to set and run a function from a string and set the returned value to the value of the string. e.g.
<?php $hi = function(){ return "Hello World"; };
echo $hi(); ?>
It probably is not possible but please post anything similar.
Anonymous functions were introduced in PHP 5.3.
