PHP 5 vs PHP 7
PHP stands for hypertext preprocessor and is used as a server-side scripting language mainly designed for web development. It came into action after mid-1994 and was developed by Rasmus Lerdorf. After its launch, it became the most recognized programming language amongst the developer community, with around 80% industry-standard supporting PHP as the main development language surpassing its biggest competitor, ASP. NET with only 19 % market remaining and other languages like RUBY, Java far behind the competition. And in the latest update, the PHP developers introduced the latest version of PHP, PHP 7, with claims to be twice as fast as its previous version, PHP 5.
PHP 5 was a major change in the development field. The PHP development team majorly focused on the missing areas not present in any of the previous versions. The main areas of development included Object-Oriented Programming, XML ( Extensible mark-up language), and My SQL support. The updated version included Destructors, Constructors, Interfaces, Class type hints, Abstract, classes, Static properties and methods, Final properties and methods, a whole suite of magical methods.
Majorly updated features of PHP 5 are
Dmitry Stogov, Nikita Popov, and Xinchen Hui were the people behind developing the new PHP 7. They derived an experimental branch called PHP next generation, also known as PHPNG. And the development project came to a success. The development community gladly accepted the new language due to the visible advancement in technology. These developers continued the development of PHPNG and released the stable version in 2015 called PHP 7.
Unlike others, PHP7 offers faster performance. Moreover, they guarantee 100% performance and speed improvement compared to PHP 5. It gave an upper hand to web developers and enabled them to design quick interactive websites that can render interactive visual features and respond to the input request. Also, it is much affordable compared to PHP 5 as it requires less energy to power servers. Also, this new update was launched with new syntax and features that make development easy.
Majorly updated features of PHP7 are:
1) Return type included in PHP 7, we can use it after the closing parenthesis of the argument list
The above example consists of a function program_1 that will return an array.
2) A new operator called spaceship operator was introduced, and it became a very important part of programming as it helps the developer sort combined comparisons. We can easily compare two expressions using this operator.
In PHP 5 and earlier:
In PHP 7:
3) The null coalescing operator assigns a variable according to whether the first value is null or not. The major advantage of using this is that it reduces the time and syntax required to check if a value is null and then assign a new value.
In PHP 5 and earlier:
In PHP 7:
4) Object-oriented exceptions are introduced.
5) It combines static typewriting, which enables static analysis and static error detection.
6) Unicode code point code syntax was introduced in PHP7.
7) Mysql_ * functions are now replaced with mysqli, also known as the intelligent version of My SQL.
Difference between PHP 5 and PHP 7
Here are the following differences between PHP 5 and PHP 7, such as:
Form the above discussion. We can conclude that PHP 7 is far more advanced than any of the PHP versions in terms of speed and connectivity, which is the most advantageous upgrade a PHP developer will come across. Indeed it is necessary to consider an upgrade in the growing web market. A client expects fast connectivity.
PHP 7 is an improved version of PHP 5 that provides faster performance in less storage. Although PHP 5 codes are simple to understand, PHP 7 provides a complete and easy coding system to work on. PHP 7 upgraded engine is the next generation design and supports fatal error handling and alternative running of several combined activities, which provides the PHP 7 developer an upper hand.
We can conclude that PHP 7 can be the future of PHP all. At some point, all currently running applications must upgrade to PHP 7.
