For many, PHP is the lifeblood of web development.

It may be a general-purpose scripting language, but it powers WordPress, Drupal, Magento, and more; not to mention the thousands of individual PHP scripts available. If you've got a problem that needs an online solution, more than likely, you can solve it by creating a PHP script—or downloading something already built.

PHP is clearly suited for web development. Take these 20 popular PHP scripts available on Envato Market, for example:

1. Vanguard - Login and User Management

If you run a website of any sort and are looking to introduce some type of login and authentication management, then take a look at Vanguard.

In short, Vanguard is a Laravel-based application that makes it possible to introduce user-registration, login, and authentication (through a variety of techniques) to a pre-existing website.

Some of the features it offers include:

• Interactive Dashboard
• Unlimited number of user roles
• Powerful admin panel
• Unlimited number of permissions
• Super easy installation using installation wizard
• User Activity Log
• Avatar upload with crop feature
• Built using Twitter Bootstrap

• Fully customisable from settings section
• Complete and detailed documentation
• Fully object oriented and commented PHP and JavaScript code.

If you run a website and are trying to figure out how to introduce memberships without moving to a completely different platform, give Vanguard a try. Perhaps it'll give you exactly what you need.

2. Booking System

Booking System, aka BookingWizz, is a wiz at managing reservations for any website offering services, lessons, and event reservations.

Packed with plenty of power, this easy-to-set-up booking script has a clean design and is fully responsive.

Called the "'Swiss Knife' of Booking Software," you can easily see why:

• You can book multiple events and services.
• Users can print their details to PDF.
• Organizers can keep an eye on things with the Admin Dashboard.
• Schedule single-day services, multi-day services, and events.
• You can even book phone customers by using the manual booking option!

This barely scratches the surface of what it can do. When you begin to expand into the Booking System add-ons, you'll even find more power, like notifying clients using SMS with 10 SMS gateways.

Impressive.

3. PHP Login & User Management

There's no need to use an entire CMS to handle user logins and have private pages that can only be viewed by logged-in visitors to your website.

This can easily be done by leveraging PHP Login & User Management, a MySQL-powered website PHP login script. You can even change User Levels using the built-in Control Panel when you need different levels of page security.

This script includes:

• login expiration

With the installation wizard and the HTML5 Twitter Bootstrap design, you'll be up and running with solid PHP Login & User Management in no time.
