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);

    $errors[] = Mage::helper('customer')->__('your error message here');
}

3rd parameter must be an array (see my answer) ;) – Raphael at Digital Pianism yesterday
    
@RaphaelatDigitalPianism, yep but it must have the key pattern in it. See my update answer :) github.com/OpenMage/magento-mirror/blob/magento-1.9/lib/Zend‌​/…. And it works with a simple string also – Marius♦ yesterday
    
Sure about the key pattern ? github.com/OpenMage/magento-mirror/blob/1.9.2.4/app/code/cor‌​e/… – Raphael at Digital Pianism yesterday
    
Oh ok yeah here we go again posting the same answers ;) – Raphael at Digital Pianism yesterday
    
Thank you @Marius I will test the code. – Elvis yesterday

I reckon you should use Zend_Validate_Regex in that case.

You could do:

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

if (strlen($password) && !$validate->isValid($password)) {
}

Alternative

You can also do:

if (strlen($password) && !Zend_Validate::is($password, 'Regex', array("/(?=.*[\d])(?=.*[a-z])(?=.*[A-Z])(?=.*[!@#$%^&])[0-9a-zA-Z!@#$%^&]{10,16}/"))) {
}
