Best leading PHP frameworks in 2019

The top 10 PHP frameworks

Here’s a list of the best PHP frameworks, based on popularity and ability to facilitate application development.

1. Laravel
2. Symfony
3. CodeIgniter
4. Zend
5. CakePHP
6. FuelPHP
7. Yii 2
8. Phalcon
9. Slim
10. PHPixie

1. Laravel

If frameworks were people, Laravel would probably be the king. If you want to code beautiful designs, you’re looking for Laravel since it’s positioned as the go-to PHP framework for web artisans.

The reason for its wide popularity boils down to ease of use and virtually no learning curve. And despite that, it’s a framework developer use for some serious work. So it may seem like a simple tool at first, but it’s a beast when it comes to producing concrete work.

2. Symfony

When it comes to developing large-scale enterprise projects, Symfony makes a perfect choice amongst the PHP frameworks. Its ecosystem is a huge one, with a big set of reusable components and an active community of developers. The components serve the purpose of completing diverse tasks such as for creation, the configuration of objects, authentication, routing, templating, and much more. These components are being used to power up projects such as Drupal, Laravel, PHPBB, PIWIk, and OROCRM.

3. CodeIgniter

CodeIgniter is one of the oldest frameworks but is simple and powerful. It can easily be installed and requires minimal user configuration. It works perfectly on almost all shared and dedicated hosting platforms. CodeIgniter isn’t entirely based on the MVC framework. Models and Views are optional, but Controller classes are a must. Another strength of CodeIgniter is speed. It runs faster with database tasks in comparison to other frameworks. CodeIgniter is well documented and a good framework to start with for PHP beginners.

The amount paid as Repayment of Principal Amount of Home Loan by an Individual/HUF is allowed as tax deduction under Section 80C of the Income Tax Act. The maximum tax deduction allowed under Section 80C is Rs. 1,50,000.

This tax deduction under Section 80C is available on payment basis irrespective of the year for which the payment has been made. The Amount paid as Stamp Duty & Registration Fee is also allowed as tax deduction under Section 80C even if the Assessee has not taken Loan.

However, tax benefit of home loan under this section for repayment of principal part of the home loan is allowed only after the construction is complete and the completion certificate has been awarded. No deduction would be allowed under this section for repayment of principal for those years during which the property was under construction.

TAX BENEFIT ON HOME LOAN (INTEREST AMOUNT)

As per Section 24, the Income from House Property shall be reduced by the amount of Interest paid on Home Loan where the loan has been taken for the purpose of Purchase/ Construction/ Repair/ Renewal/ Reconstruction of a Residential House Property.

The maximum tax deduction allowed under Section 24 of a self-occupied property is subject to a maximum limit of Rs. 2 Lakhs (increased in Budget 2014 from 1.5 Lakhs to Rs. 2 Lakhs).

In case the property for which the Home Loan has been taken is not self-occupied, no maximum limithas been prescribed in this case and the taxpayer can take tax deduction of the whole interest amount under Section 24.
