set multi username and password

[zapa]

function login($username, $password) { 
$user = "1"; 
$pass = "1"; 
if ($username != $user &&  $password != $pass) { 
$login_action = "fail"; 
} else { 
$login_action = "true"; 
} 
return $login_action; 
} 

how can i set more then one user name and password, i.e
$user = joe, sam, amy

User: Joe pass: Joe122
User: Sam pass: Sam142
User: Amy Pass: Amy123
etc..

Thanks,

Put them in an array

$user_pass = array("user1" => "pass1", "user2" => "pass2");

Then iterate through the array when doing the validation

foreach ($user_pass as $key => $value){
  echo "User: $key, Pass: $value<br>";
}

ok yes thats good.

How can i check if one of Array is the correct password and username?

I tryed this:

if($HTTP_POST_VARS['submit']) {
	    if($HTTP_POST_VARS['password'] == "$value" & $HTTP_POST_VARS['username'] == "$key"){
do this....
}
}

Need a little more help, thanks

I would say, use an array as already suggested or if you plan on having many users, put them into a database.

e.g.

//return true if username/password valid, else return false
function login($username, $password) {
	//declare array of usernames and corresponding passwords
	$user_pass = array(
		'Joe' => 'Joe122',
		'Sam' => 'Sam142',
		'Amy' => 'Amy123'
		);
	//loop through array
	foreach ($user_pass as $user => $pass) {
		//given username/password matches a pair in the array
		if ($user === $username && $pass === $password)
			return true;
	}
	//no matches found
	return false;
}

or you could do it this way...

//return true if username/password valid, else return false 
function login($username, $password) { 
    //declare array of usernames and corresponding passwords 
    $user_pass = array( 
        'Joe' => 'Joe122', 
        'Sam' => 'Sam142', 
        'Amy' => 'Amy123' 
        ); 
    //loop through array 
    return ($user_pass[$username]==$password);
}
