This is what im trying to do and I can figure it out, The variable $name = gruhn, I want to check if $name == $gruhn. How could i make it so it adds the $ on the front of the value of $name?

Sorry but I don't understand your question. It seems simple enough, but I'm just not sure what you mean Smile. Could you rephrase? Wink

Ok, Il try to explain this better, although it is hard to explain. The variable $name contains the username, ex: gruhn. The variable $pass contains the password they entered. There is a variable for each user that contains there real password, like the variable $gruhn contains gruhns password, etc. If the name in $name is gruhn I want to see if $pass == $gruhn. If the name in $name is karlyn I want to see if $pass == $karyln without using an if statment for each one.

Code:
if ($pass == $$name) {
  $correct_password = true;
}


Question

[The double $ sign is intentional Smile]

$$name, eh? cool...though I think it would be better if the usernames/passwords were stored in arrays, would just be tidier.

Yes, I have to agree with adam, storing passwords in such a way is crazy, unless you only have a few Smile.

If $name = 'Daniel' then $$name is the same as $Daniel
Nice, isn't it Razz

I only have 11 passwords plus they come out of a database so they have to be seperate.
