Copy-pasting an error message is not the same thing as asking a question. — user229044, Dec 08 '13 at 02:45

Define it at the top of the document.

<?php

    $errors = false;

Alternatively, check if it is set using a ternary where assignment is necessary.

echo isset($errors) ? $errors: '';

Where '' can be replaced with whatever assignment correlates to the requirements.

`s/ternary/conditional operator/`. And does `$errors;` on its own really function as a declaration? – Lightness Races in Orbit Dec 08 '13 at 02:40
@LightnessRacesinOrbit In any version of PHP above 4, it does function as it's down declaration *edit* AFAIK. – Ohgodwhy Dec 08 '13 at 02:40
@Ohgodwhy: [Nope, doesn't seem so](http://ideone.com/i6Gxpf), at least not in PHP 5.4.4. – Lightness Races in Orbit Dec 08 '13 at 02:43
@user3078998 That's because it's not an array. Your initial conditional statement fails due to the fact that the value `$_POST['submitted']` is not set. Due to this fact, errors are never turned to an array. Debug the variable, `echo '
```
', print_r($errors), '
```
';`.

@LightnessRacesinOrbit Fair enough, could've sworn empty declarations work, oh well, I'll just remove it. – Ohgodwhy Dec 08 '13 at 02:45
It's an empty-ish statement but there's no declaration there whatsoever. – Lightness Races in Orbit Dec 08 '13 at 02:45
