Joomla 3.5 and its PHP 7 support and introduction of other new features

Many users always look forward to new versions of their preferred software tool as it could bring them new features for getting the desired outcomes comfortably and Joomla 3.5 is not an exception. Joomla always encourages contributions for a particular release. The CMS developer pays heed to the patches that are required to be tested and ensures that the features identified by Joomla on the roadmap for that specific release are addressed by volunteers who are curious to get involved.

You may be thinking what Joomla 3.5 brings to you. As an online blog or e-commerce store owner, how you can offer a pleasing shopping experience to your customers.

Long awaited PHP 7 Support in Joomla

Hot news in Joomla 3.5 is that it can finally support PHP 7! Using PHP 7 can improve the speed of the site dramatically.

Joomla always puts efforts to design advanced CMS solutions. With the release of version 3.5, PHP 7 is officially supported. It has been proven that it's nearly 50% increase in performance. This is in some cases outperforms Facebook's HHVM, which utilizes its own JIT (Just-In-Time) compiler.

Why You Need to Switch Over to Joomla 3.5?

With each PHP release, you could find that new functionality was added. In addition, stability and speed were improved. PHP 5 supported object-oriented programming, which allowed developers of Joomla for writing better codes and take advantage of object-oriented programming paradigms. The security and stability of Joomla are highly influenced by the features that are added to PHP and its version. We don't have to repeat, that it's important to stay up to date with most recent stable PHP version, because older major version is going to be discontinued as per Joomla's support policy. It happened in the past that there were security issues found in older versions of PHP. If such website used older version, it could not be able to get security patch that easily.

Improvements Done in PHP 7 and how they affect Joomla

After testing PHP 7 with the Beta 2 version of Joomla 3.5, the loading time of HTML output was reduced by 10% to 30% approximately. This is a major achievement from a simple change in the PHP version.

The improvement on PHP 7 is much noticeable on high traffic pages. If the web server fulfills around 100 requests per second with PHP 5.6, then the same server can handle between 200 and 300 requests per second with PHP 7. PHP 7 can offer advantages to computationally intensive and complex extensions of Joomla.

Backward Compatibility Why Joomla's internal code had to be slightly changed and released? Joomla deployed JString as a class with the launch of Joomla 1.5. A framework package was introduced in Joomla 3.3 which had a duplicate class known as “string”. JSstring was made for extending the framework string package because they were duplicates. In PHP 7, “String” is a protected class name. This causes conflict with PHP 7 class. If you keep using JString, you would not experience issues of backwards compatible break. However, if you use the framework package directly, then backward compatibility break would occur.

Many users do not understand whether they need to switch over to PHP 7 Currently, many web hosting companies still prefer PHP 5.6 or 5.5. For web host, providing new PHP version involves cost, which companies tend to avoid. Users could potentially blame web hosting company instead checking the compatibility list themselves. You can directly ask your hosting company to offer PHP 7 support.

Importance of PHP 7 for Extension Developers Any person who works on code with the “String” of PHP 7 has to upgrade the code and replace the same with “StringHelper”. If the code has not undergone update, the extension would stop working with Joomla 3.5. This change can be made easily.

Relase Date of Joomla 3.5 Official date of Joomla 3.5 release is February 17, 2016.
