# Regexs

much more flexible; matches patterns

\===============================================

foolproof your server. people are good at (even accidentally) finding bugs or exploits.

use regexs to allow for more flexible stuff, that way less likely something is not accepted and breaks code.

(like capitalisation)

example:

if arg-1 = "example":

if they have caps lock, they might use "EXAMPLE", and then the code wouldnt run

ie can accept variation: colour and color
