The Exciting Features of PHP 7 That You Should Know About

Untitled

Are you the owner of a website or a web developer? Does your website run on PHP-enabled CMS such as Joomla, Drupal, Magento or WordPress? If your answer to these questions is “yes”, then I have good news for you! The PHP 7 is released and it contains a number of new and exciting features. To make you aware of these cool features, we have decided to dedicate a post on it. So let’s begin.

  1. Scalar type hints
In PHP, Type hints are available for quite a while now. The sad part is that they were restricted to arrays, classes and callables. If you add scalar type hints and enable strict requirements, it can be said that self-documenting as well as correct PHP programs can be written. Also, you can have more control over your code and make it much easier to read.
  1. The all-new Zend engine
Since the year 1999, PHP is being powered by the Zend engine, which was introduced with the release of PHP 4. Make sure not to confuse Zend with the Zend framework. Written in C, Zend is actually an open-source execution engine that interprets the PHP language. The Zend Engine II is used by the PHP 5.X series. It not only adds an extensible object model to the language, but also enhances the functionality of the initial engine. A brand new version of the engine is received by PHP 7 that comes with the code name of PHP#NG (Next Generation). You can get hold of this new engine, if you go for php development.
  1. Improved speed
Now, who doesn’t love speed? Keeping that in mind, the developers have worked very hard so that they can refactor the PHP codebase. The result is an increased performance and reduced memory consumption. The benchmarks for PHP 7 show the speed that is twice as fast as PHP 5.6 and sometimes even faster! However, for your project, the same result cannot be guaranteed, as the benchmarks were tested against some of the major projects, WordPress and Drupal and these numbers do not come from any abstract performance tests.
  1. Error handling
For PHP developers, it has never been easy to handle catchable and fatal errors. With the new Engine Exceptions, you can now replace these types of errors with exceptions. PHP will continue returning the same fatal errors if the exception is not caught. The \Exception Base Class is not extended by the new \Engine Exception objects. This results in two different types of exceptions in handling error along with ensuring backward compatibility.
  1. Spaceship operator
With spaceship operator, it becomes much easier for you to compare values. This operator does not return a true/false value. Instead, depending on the result of the evaluation, it returns one of the following values –
  • -1 when the right value is greater than the left value
  • 1 when the right value is less than the left value
  • 0 when both the right and the left values are equal
 
  1. Null Coalesce Operator
This operator is used as shorthand to check if a value is null or set within inline comparisons. In order to return the value if it is set, you can just use “??” instead of doing the same old isset check again and again. In conclusion, it can be said that some features of PHP 7 have been removed.   At Digital Aptech, we have a team of experienced PHP developers who have great expertise in their field and know how the new features work.
