I would like to **place a RegEx Code in PHP code to validate a password**. Example below of current code:

    if (strlen($password) && !Zend_Validate::is($password, 'StringLength', array(6))) {
        $errors[] = Mage::helper('customer')->__('The minimum password length is %s', 6);
    }

I would like to replace the `array(6)` with this regular expression with `preg_match`:

    preg_match("/(?=.*[\d])(?=.*[a-z])(?=.*[A-Z])(?=.*[!@#$%^&])[0-9a-zA-Z!@#$%^&]{10,16}/", $input_line, $output_array);
