Try this:

foreach($errors[] as $val)

Forget that last suggestion as it did not work for me.

Your script seems to work when a value has been assigned to $errors, but when there is no value set, it causes an error.

If that is correct, a solution is to:

1. Connect a default value to $errors.
2. Try / Catch block to catch the error and take the necessary action.

Assumption about 2 above:
The web server has a PHP version where exception handling is implemented, PHP 5+.

AHH..

When I wrapped it to check for value, it seems to work.

if(!empty($errors))
{
  foreach ($errors as $val)
   {
       echo "ERROR: $val <br/>"; 
   }
}

$errors is only created if there is an actual error. if($errors) tests if the $errors variable contains a value other than false, but if no errors were generated, $errors is never created. There are two solutions.

1. Make the first line of the script $errors=false; This will cause the script to work, because the if condition will fail if no errors are generated.
2. Replace the if($errors) test with if(isset($errors)) which checks if the variable exists. Since the variable currently only gets created if there is an error, if $errors has not been created the test will fail.

Note, these are two ways of accomplishing the same task. Do not do both.
