2 Neat Little PHP Tricks

In writing a function to validate bank routing numbers, I came across two simple techniques, that I know I will need to use again:
PHP Trick 1: Remove All Characters Except Numbers from a String
A simple little regex does the trick:
PHP Trick 2: Loop Through a String Character by Character
Setting two variables in a for loop does the trick (that could be trick number 3...):
- echo $routingNumber[$i]; //access to each character in a string
- }
Cheers,
