[SOLVED] strip down string

[joecooper]

how can i strip down a string to make it into text and numbers in lowercase only, a-z 0-9 only and remove all spaces

 

so say:

 

$fullname = "This-Is An! Example234";

 

it would turn it into:

$fullname = "thisisanexample234";

$string = "This-Is An! Example234";

$string = preg_replace('/[^0-9a-z]*/','',strtolower($string));
