well i want to do so when somebody submits a form with the format wrong, it will echo "Wrong format", the format has to be STEAM_0:x:y

 

x meaning either one number of 1 or 2

y meaning any number forever

 

 

<input type="text" name="steamid">

 

<?php

if(?){
echo "right format"
} else {
echo "wrong format"
}
?>

preg_match('%^STEAM_0:[1-2]:[0-9]+$%', $str) > 0

i think you mean you want a tutorial on regular expressions, the php preg_ functions make use of regular expressions, but if you dont know how to create them the preg functions are useless... try googleing regular expression tutorial or regex tutorial

Another good tool to use while learning regex, or even after you've learned it is regex coach... google it.
