PHP frameworks are like onions because they make you cry. No, I mean they are like onions because they have layers, that's what I meant.

What is a PHP framework?

A PHP framework is built on the open-source language PHP and offers built-in features to improve your software development lifecycle. These features increase development speed and improve performance within your team by lowering the workload of your developers.

PHP has been around for many years, and as a result, it is extremely robust. For everything from computer programming, to software and web development, PHP is a cornerstone in the development community. Developers use it to create desktop applications, games, command-line scripting, automation services, and much more.

Given the wide variety of its use, it has a decent learning curve — enter PHP frameworks. These frameworks ease the learning curve by providing pre-built software, rules, and platforms to build your software.

Why use a PHP framework?

PHP frameworks provide multiple benefits that improve your development pipeline. These improvements cover everything from security to productivity within your organization. Each of these frameworks has different focuses — some may focus on development workflow, and others may focus on scalability.

One perk that all of these frameworks offer is excellent security which is vital for software development. Maintaining security from the beginning of your development pipeline is akin to a DevSecOps approach which leads to improved performance.

Drawbacks of Using a PHP Framework (Cons?)

There are a few drawbacks to using a PHP framework for your software development teams. The first is an increase in programming restrictions — in fact, you can do far more with PHP if you don't use a framework. The downside is an increase in programming complexity, requiring far more manual programming to accomplish your goals.

Another drawback is that with each framework comes a learning curve to understanding how to interact and use that specific framework. This learning curve is not nearly as big a problem as learning an entirely new programming language but it is still worth considering.

11 Best PHP Frameworks

Let's discuss some of the best PHP frameworks and their overall difficulty, considering aspects like, getting started, learning the language and syntax, and complexity. (Easy, Moderate, Difficult)

1. Fat-Free Framework

This framework is made for fast startup and minimal asset overhead. This reduced footprint allows for wicked fast setup and better runtime speeds for your projects.

This framework is probably one of the most comprehensive frameworks on this list. It provides only the basics but is extremely extensible allowing you to do almost anything you need. It also offers security features and promotes the MVC architecture, but is not limited to it.

  • Difficulty: Easy
  • Highlight: Ideal for beginners, good documentation available
  • Drawback: Not a good choice for security

5. Laravel

Laravel is a web application framework with expressive, elegant syntax. Laravel is one of the world's most popular open-source frameworks and is B2B ready. It was created to offer a framework that provides features that CodeIgniter doesn’t, such as user authentication.

Laravel includes security features to protect against SQL injection and Cross-Site Forgery Requests (CSFR), workflow tools such as asset compilers, and a command-line interface (CLI). This framework focuses on improving workflow efficiency making it a useful tool for your team, but the added features make it a little harder to learn.

  • Difficulty: Moderate
  • Highlight: Suitable for any needs from small to large applications
  • Drawback: A bit more complex to use, better for large projects

6. Laminas

Laminas, previously known as “Zend Framework” is a collection of professional PHP packages with more than 570 million installations. This framework has been around for a very long time and has a massive community of developers and users that support this framework.

Due to its long life, Laminas has a robust amount of features that have been added and incorporated which steepens the learning curve. On the other hand, this framework has been around so long it is constantly being updated with optimization and efficiency changes.

  • Difficulty: Moderate
  • Highlight: Flexible, robust, and has a massive community base
  • Drawback: Exceedingly steep learning curve for mobile developers

7. Cake PHP

Symfony also follows PHP and web standards to the exact letter, relieving concerns of being compliant throughout the development process.

This framework is best suited for larger enterprise-level projects, it is very flexible and is capable of integrating with larger projects such as Drupal. Symfony and Laravel have a lot of commonalities, however, the defining point is that Symfony is built with experienced developers in mind.

  • Difficulty: Difficult
  • Highlight: Boasts extreme control and flexibility, enterprise-ready
  • Drawback: Steep learning curve, slower than other frameworks

Choosing the Best PHP Framework

Choosing the best frameworks for your team can be a little stressful, but being properly informed will help. Let's wrap up by going through some tips on choosing the best one to fit your needs.

Popularity and Community

Using a framework that has a large community often means you'll struggle less when looking for answers to common questions. It also means that you will be more likely to find answers to less common questions.


Finding a framework that matches the ideals and culture of your organization is a frequently overlooked concept. The importance of matching culture should not be underestimated, if a framework does not meet your organization's goals and ideals, look elsewhere.


Sustainability matters because it determines if the framework you are using will still be around later. Not much is worse than rebuilding a project because a framework is no longer in production and thus contains outdated information or technology.

Sustainability matters concerning the scalability of your project. As your project grows, will the framework you are using continue to sustain it?

Software and Technology Support

Using a framework that offers greater flexibility is nice, but be sure to consider the level of support offered with it. Ensure the framework you choose offers good software and technical support so that your development process is not halted due to roadblocks that you cannot surmount.
