It would be better if you reformatted first since this is ambiguous when 
you have the following date:

     6/7/2013

Here's a completely unambiguous solution:

<?php

     $old = '24/7/2013';

     $paddy = function( $bit ){ return str_pad( $bit, 2, '0', 
STR_PAD_LEFT ); };
     $new = implode( '-', array_map( $paddy, array_reverse( explode( 
'/', $old ) ) ) );

     echo $new."\n";

?>

Cheers,
Rob.
