Which PhP framework is better for large scale application like Bayt, Dubizle and Social Network?

I will suggest laravel is best you can the request handle by laravel is great then everyone.

I would suggest using Laravel Framework. As it has an amazing ecosystem. Since large scale application has requirements for:

1. Scaling

2. Good Database

3. Easy to use framework

 

Laravel has all the great features:

1. It provides Laravel Forge to manage servers which helps in scaling the application

2. Provides Connections to No SQL Database which are helpful if you are developing social networks. e.g. data which is of different shapes and sizes

3. Forge has intergrations with Git Respositories which can used for push to deploy

4. Using Digital Ocean or any VPS Provides can be linked to Laravel forge. 

5. Amazing REST API Development.

6. Easy development.

Usually a large scale application involves more than just a framework, I would recommend using Laravel framework for the basic application operations as it's highly supported and liked by a lot of developers but you should keep in mind that some operations that require handling tremendous amount of data would require a different more native approach in order for it to be fast and effecient that also includes different types of databases and front end frameworks.

for large Enterprise apllication you have to choose CI,or Laravel Framework of php.

the best one is Laravel go faster by codeigniter

laravel, Zend etc. The better tool is what you know how to use it efficiently.
