Question

ok…in php how do i do this? given the following scenario:

// array of letters var $letters = array('a', 'b', 'c'); // loop through array and create empty arrays with names like $a, $b, $c foreach($letters as $letter) {     var $$letter = array(); } 

Answer 1

Your code was almost correct. You just need to remove ‘var’ on the 2nd and fifth lines.

// array of letters $letters = array('a', 'b', 'c'); // loop through array and create empty arrays with names like $a, $b, $c foreach($letters as $letter) {     $$letter = array(); } 

This works correctly (as you described). I tested it.

As an aside, I would recommend against using eval() in your PHP.
