FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Please rate this library. Is it a good library?

Informations about the package auth

Auth

Authentication and level based authorization for PHP.

Installation

Install using composer

composer require jasny\auth

Setup

Jasny\Auth is an abstract class. You need to extend it and implement the abstract methods fetchUserById and fetchUserByUsername. Also set the $secret property to a randomly selected string.

You also need to specify how the current user is persisted across requests. If you want to use normal PHP sessions, you can simply use the Auth\Sessions trait.

The fetch methods need to return a object that implements the Jasny\Auth\User interface.

Authorization

By default the Auth class only does authentication. Authorization can be added by impelmenting the authorize method.

Two traits are predefined to do Authorization: Authz\byLevel and Authz\byGroup.

by level

The Authz\byLevel traits implements authorization based on access levels. Each user get permissions for it's level and all levels below.

For authorization the user object also needs to implement Jasny\Authz\User, adding the hasRole() method.

/**
 * Check if the user has the specified security level
 * 
 * @param int $level
 * @return boolean
 */
public function hasRole($level)
{
    return $this->security_level >= $level;
}

by group

The Auth\byGroup traits implements authorization using access groups. An access group may supersede other groups.

For authorization the user object also needs to implement Jasny\Authz\User, adding the hasRole() method.

/**
 * Check if the user is in the specified security group
 * 
 * @param string $group
 * @return boolean
 */
public function hasRole($group)
{
    return in_array($group, Auth::expandGroup($this->group));
}

Usage

Authentication

Verify username and password

Auth::verify($username, $password);

Login with username and password

Auth::login($username, $password);

Set user without verification

Auth::setUser($user);

Logout

Auth::logout();

Get current user

Auth::user();

Authorization

Check if user is allowed to do something

if (!Auth::authorized('admin')) die("Not allowed");

Signup confirmation

Get a verification hash. Use it in an url and set that url in an e-mail to the user

Use the confirmation hash to fetch and verify the user

Forgot password

Forgot password works the same as the signup confirmation.

Use the confirmation hash to fetch and verify the user
