Hiyas, Just stuck on a little problem.

at the moment I have error variables store with information -

error.php
<?
$exc1001 = 'Email addresses does not match!';
$exc1002 = 'Wrong username and/or password';
$exc1003 = 'Incorrect password';
?>

Now when the a script outputs an error its redirected to this error page.
It stores what error it has encountered in the address bar.
error.php?error=1001

What I am wanting is instead of using lots of if's to write a simple script that checks what error is in the address bar and then check the list of errors, then outputs that error.

PHP Code:

$err[1001] = 'Error 1001';
$err[1002] = 'Error 1002';
$err[1003] = 'Error 1003';

if (isset($errors[$_GET['error']])) {
   $error = $errors[$_GET['error']];
}
else {
   $error = 'Unknown error';
} 


PHP Code:

<?
  $err[1001] = 'Error 1001';
  $err[1002] = 'Error 1002';
  $err[1003] = 'Error 1003';
  $err[1004] = 'Error 1004';
  $err[1005] = 'Error 1005';

if (isset($errors[$_GET['error_code']])) {
   $error = $errors[$_GET['error_code']];
}
else {
   $error = 'Unknown error';
}

echo $error
?>

All this outputs is Unknown Error when error_code=1004 etc.
Thankyou for your reply

Solution was valid but had a typo, try:

PHP Code:

<? 
$err[1001] = 'Error 1001'; 
$err[1002] = 'Error 1002'; 
$err[1003] = 'Error 1003'; 
$err[1004] = 'Error 1004'; 
$err[1005] = 'Error 1005'; 
 
if (isset($err[$_GET['error_code']])) { 
$error = $err[$_GET['error_code']]; 
} 
else { 
$error = 'Unknown error'; 
} 
 
echo $error 
?>

A simple switch statement would help you here

PHP Code:

<?php
$error= intval($_GET['error']);
switch ($error) {
case 1001:
    echo "Email addresses does not match!";
    break;
case 1002:
    echo "Wrong username and/or password";
    break;
case 1003:
    echo "Incorrect password";
    break;
default:
    echo "Error undefined";
    break;
}

?>

Thankyou very much both of you.

Both work fantastically and I think I will go with the switch as I haven't used that before and I like collecting working Scripts I can apply to other sites I may make in the future.

Both of your Talkupation! points have clicked on

Thanks again

It is better to use switch if you need to perform some extra action in different cases. If you only need to set the value of a single variable you should use indexed array.
