Guide: Everything You Must Know About PHP 7

Are you a web developer or a website owner? Are your sites running on CMS with PHP, such as WordPress, Drupal, Joomla or Magento? Then I have good news for you: the feature-full beta of the new PHP 7 has recently been releasedThe main release 7.0.0 contains so many cool ones features that we have decided to devote an entire post to it. But first we need to add a few reminders.

Note that PHP 7 is still in the development phase do not use it in production until November when the final version will come true. As a prospective user, if you want to get a fair share of the development process, you can help download the latest beta, play with it in your testing environment, and report bugs you found during testing. Here’s the project’s timetable to find out when the next beta is available.

With that out of the way, let’s take a look at PHP 7.

1. The name is PHP 7 (not 6)

The current stable release uses the version number PHP 5.6. After some dispute, the development team decided they would omit the PHP 6 name for the next major release. PHP 6 already existed as an experimental project in the past but never reached the production phase.

To prevent users from mixing up the previous attempt with the latest development, the new major release will run under the name PHP 7.

2. The brand new Zend engine

The Zend engine has been feeding PHP since 1999, when it was introduced with the then-new PHP 4 release. Zend – not to be confused with the Zend Framework – is an open-source execution engine written in C that interprets the PHP language. The current PHP 5.X series is used Zend Engine II that improved the functionality of the original engine and adds a extensible object model and a significant performance improvement to the language.

PHP 7 will receive a brand new version of the engine that comes under the code name PHP # NG (Next Generation).

3. Twice the speed

The most easily recognizable benefit of the new PHPNG engine is the significant performance boost. PHPNG’s development team redesigned the Zend Engine and remarkably optimized memory usage.

The results? Below are the performance benchmarks of the Zend Performance Team. By not just using PHP 7 your code will run faster but you will too require fewer servers to serve the same number of users

4. Facilitates error handling

To say the least, dealing with fatal and recordable fatal errors has never been an easy task for PHP coders. The new Exceptions to the engine you can replace these types of errors with exceptions. If the exception is not caught, PHP will continue to return the same fatal errors as in the current 5.X series.

The new EngineException objects extend the Exception Basic class. This ensures backward compatibility and results in two different types of error handling exceptions: traditional and exceptions to the engine

To enable programmers to catch both, PHP 7 introduces a new one shared parent class under the name of BaseException

5. Support for 64-bit Windows systems

PHP is a prominent member of the LAMP stack, meaning that the native environment is Linux, but it is also possible to run it on a Windows system. The 5.X series does not yet support 64-bit integers or large files, so x64 builds have been accounted for so far experimental

PHP 7 will change this like it does introduces consistent 64-bit support meaning both native 64-bit integers and large files are supported, so you can run the language on your 64-bit Windows system with confidence in the future.

6. New Spaceship and Zero Coalescent Operators

The Spaceship operator runs under the official name Combined Comparison Operator. The format of the new operator looks like this: <=> (kind of like a simplified spaceship, if you imagine it correctly).

The spaceship operator returns 0 if both operands are equal, 1 if the left is greater, and -1 if the right is greater. It is also called one triple comparison operator, and it already exists in other popular programming languages ​​such as Perl and Ruby.

The operator Null Coalescing is indicated by two question marks (??). You can use it when you want to check if something exists and return a default value, just in case it doesn’t. The coalesce operator returns the result of its first operand if it exists and is not zero, and the second operand in all other cases.

This is how the new operator shortens the time spent on basic returns:

7. Enables accurate type declarations

Have you ever wanted to prevent accidental return values ​​by declaring the return type of a function? Well, the new PHP 7 allows developers to improve the quality of their code using return type declarations.

The image below shows a very simple use where the foo () function must return an array. Check out more complicated examples here.

Around the feature more so, PHP 7 introduces 4 new type declarations for scalar types: int, float, string and boolThe new scalar types allow developers to specify that they expect integers, floats, strings, or booleans to be returned. The new scalar types introduced by PHP 7 will also be supported by Type Hints argument that allows developers to force type parameters since the PHP 5.X series.

8. Adds anonymous classes

PHP 7 allows you to use anonymous classes, already an established practice in other object-oriented languages ​​such as C # and Java. An anonymous class is a class without a name. The object it instantiates has the same functionality as an object of a named class.

The syntax is the same as what we are used to in traditional PHP classes, only the name is missing. When used properly, anonymous classes can speed up coding and execution timeAnonymous classes are excellent when a class is used only once at runtime and in cases where a class does not need to be documented.

9. Facilitates import from the same namespace

The new Group Use Declarations feature will be a godsend to those of you who want it import many classes from the same namespaceThe new syntax reduces verbosity, makes your code clearer and easier on the eyes, and saves you a lot of typing time.

It will also be easier to read and debug codes as group use declarations will help you identify the entries that belong to the same module.

10. Cleans Up The room

PHP 7’s goal was to become free up the room to allow for improvement, so it was necessary to remove many obsolete functionalities and old and unsupported server APIs and extensions. If you want to check this in detail, click here and here.

All deleted items have been obsolete in PHP 5 for a while, so you probably haven’t used them for a long time. However, be careful if you have an old app runs on older PHP versions the new PHP 7 can possibly break the code
