Which PHP framework is the best?

You will get more feedback if you explain what you are developing. Please do not add any internet links or they will be removed as SPAM by the moderation team.

Some 10 years ago a group of my students did a study to find out. Their conclusion: some were better in some respects and not better in others respects and, of course, the other way around. Which means there is none that is best in all respects.

So the steps to answer you have to take:
1. Define your most important criteria for "best".
2. Study the tools and rank them for each criterion (say, with an 1 star to 5 star ranking).
3. Compare the results and choose the one with the highest ratings for the most important criteria.

The results can be different depending on, for example, the system you want to build and the competencies of the people in the development team and, of course, your own criteria.

Presumably, with all these tools, some good systems have been built, a lot of mediocre systems, and a few bad systems. Tools don't make the system, people do.

If you find the best framework and it's too hard for you to use then for you it's not the best.

Use the tools you can use.

A PHP framework is the best platform that helps web developer to create the web application. Basically, it delivers a structure to develop web app. Some frameworks save a lot of time, stop rewriting the repeated code and deliver RAD. My personal recommended PHP framework would be, Laravel.
If you are willing to code beautiful design, you need to use Laravel as it is considered as the go-to PHP framework for web artisans. The major reason behind its popularity is that it is easy to use. It might look a simple tool but it is a very effective medium to produce concrete work.

What is a PHP framework?
PHP frameworks are platforms for developing PHP websites. PHP frameworks provide libraries of well-known procedures, which assist in keeping down the number of unique code authors needed to develop websites in PHP. From the start, frameworks reduce the unique code one has to write, making their creation quicker and more standardised.

Best PHP frameworks

Laravel
Laravel, a free, open-source PHP framework, has become the most popular choice since its introduction in 2011. It may handle even the most complex applications securely and quickly.

Symfony
A Symfony project is well-suited for a scalable web application. It has many bells and whistles, and its component system is highly modular and versatile. Developers can select and combine the components of their projects in whatever way they desire.

CodeIgniter
CodeIgniter is an efficient and compact framework (about 2MB in size, including documentation). It is used to build dynamic websites. It includes several modules that allow you to build efficient and reusable components.

CakePHP
CakePHP is a free, MVC-based PHP framework. It's easy to use, requires minimal configuration, and produces visually impressive and feature-rich web applications.

Zend
Zend is an extensible, feature-rich enterprise-level web application framework built using the object-orientation features of Zend. It is easy to use and highly scalable. Because it follows PHP best practices, it isn't easy to adapt and follow. It is open-source and free to use. It is an excellent choice for developing feature-rich web applications.

Symfony is an excellent choice for websites and apps that need to be scalable. Its modular component system is very flexible and lets you choose the components you need for your project. Symfony supports the most databases out of the popular PHP frameworks.

laravel

Websites have become way complicated and much more demanding over time. Plus, they now provide more value compared to earlier. As most developers will tell you, PHP frameworks are the best creation tools that can give life to the websites, and in return, about 80% of the webpages on the internet are supported by PHP frameworks.

According to me the best PHP framework is Zend framework. It is developed on March 3, 2006. This framework has a collection of 60+ packages which is available on GitHub and can also be installed through composer
