Login script/ arrays for names and pswords

[Ben Rogers]

Would it be possible to make 2 arrays so that i could check if a name and password match?

By this i mean having one array holding the names, for example foo and bar

and then the second array holding ex1 example2

and then sum1 puts foo as the name and ex1 as the password, id check to see if the they matched each other then what i wanted to happen could happen?

also, could it draw the names from a .txt file?

sorry if i was unclear. if this requires excessive work, nevermind, im just making the script for sumtin i may or may not do.

You'd set up your two arrays, first.

$users = array("Jon","Darryn","Pamela","Anne");
$passwords = array("kluck","eggs","pants","wine"); 

Then you can loop through them to see if the inputted ones are correct. Assuming you've already set variables to the $_POST formdata values...

for($u=0; $u<count($users); $u++)
  {
  if($username == $user[$u] && $password == $passwords[$u]){
  # user/pass correct
 } else {
  # user/pass incorrect
 }
} 

To write to a file, you must first open it (fopen()), then select what you want to do with it--append ('a'), append and read ('a+'), read ('r'), read and write ('r+'), write ('w'), or write and read ('w+'). After you decide that, you can manipulate it with functions such as fread() and fwrite(). Be sure to close it with fclose() when you're done!

Thanks, Jona. So that's how to do arrays... when I tried to learn them php.net ranted on about key values and I was lost.

Much thanks.
