PHP Input Validation

Easy to use PHP class for validating user input from HTML form input fields or anywhere else you may use it.

Please note this is only validation, for critical operations you may need to consider sanitizing before submitting user data to DB etc. I assume you're already well aware of the dangers.

Usage example

HTML form

<form>
    <input type="text" name="email">
    <input type="submit">
</form>

PHP processing

$validate = new Validate();
$validation = $validate->check($_POST, array(
    'email' => array(
        'required' => true,
        'mailcheck' => true
    )
));

if($validation->passed()) {
    echo 'Validation passed!';
}
else {
    echo 'Validation errors:';
    echo '<ul>';
    foreach($validation->errors() as $error)
    {
        echo '<li>'.ucfirst($error).'</li>';
    }
    echo '</ul>';
}
