a variable that is undefined

[Anonymous]

i want a variable that is undefined... um.. i dunt think u understand what i'm talking about. heres my script.

<?
$user[0] = "ff-dna";
$user[1] = "mysql";
$user[3] = "john";
if ($user[$number] == "$username") { echo "access granted."; } else { echo "access denied"; } ?>

for the $number variable, is there a variable that represents all numbers... as in every number.... or checks if its a number... anyone have any idea?
