PHP simple comparison (validation) question
I have a web form input text field where i want the user to enter a 5 digit zipcode.
What is the best way (in php, not JS) to make sure it's 5 digits 0-9
I've tried < and > comparisons, but characters evidently get converted to integers and some short strings can fall within the 0-99999 range.
thanks
