For website development and related applications, PHP (Hypertext Preprocessor) always remains the most preferred language by the developers. There are a plenty of reasons behind this fact – it is user-friendly, flexible, open source language, cost effective and exhibits embedding qualities.
It is a server-side scripting language which is designed especially for website development and is also used as a general-purpose programming language. This flexible, fast and pragmatic language powers everything right from your own blog to the most successful business websites in the world.
PHP 7, the latest version of this scripting language has got much appreciation across the developers. To make this version better than all others, its developers made better use of hash lines and advanced CPU features such as registers. By making it more memory efficient, it has brought two times increased performance than its previous versions. This upgrade has featured a range of optimizations. Some of the features of this upgraded PHP 7 are as below:
- Provides consistent 64-bit support
- Exclusion of many fatal errors
- Introduction of scalar and return type declarations
- Removal of old and unsupported SAPIs and extensions
- Introduction of Null Coalesce Operator ‘??’ and Spaceship Operator ‘<=>’ for comparing two expressions (so that they require less code to perform specific evaluations)
PHP Version 7 also includes the addition of AST (Abstract Syntax Tree) which enables the PHP developers to build tools for different purposes including static analysis. Its ‘scalar typing’ feature allows you to check the correctness of your coding in advance.
Moreover, its enhanced performance ensures its quick adoption, especially from smaller hosts who’d normally not do so because they can host more customers on the same hardware. Also, PHP 7 works on a par with Facebook’s HHVM (Hip Hop Virtual Machine), which features a JIT (Just in Time) compilation which compiles PHP code all the way down to the machine instructions (if enabled).
Elimination of major bottlenecks and lower memory usage is the concrete reason behind the performance boost of this version. The web developers see a potential growth in version 7 of PHP which would successfully bring a new dawn in the era of web development.
