A framework agnostic password checker for PHP.

Installation

$ composer require acurrieclark/php-password-verifier

Usage

// include autoloader if you haven't already
include_once('vendor/autoload.php');

use acurrieclark\PhpPasswordVerifier\Verifier;

// create an instance
$passwordVerifier = new Verifier();

// default options are permissive, so  each constraint needs to be set as required
$passwordVerifier->setMinLength(8);

// constraints can also be chained
$passwordVerifier->setMaxLength(128)->setCheckContainsNumbers(true);

// check the password meets the requirements set (min length 8, max length 128, contains numbers)

$validPassword = $passwordVerifier->checkPassword("passwordToCheck");
