Have you been waiting for the release of PHP 7 ? If so, your long wait for it is becoming a reality, anytime soon. As a language for web development, it has continued to be popular among the PHP developers community. 

Undoubtedly, this server side scripting language is today the language that is much in demand. With a history of more than two decades, PHP has grown in popularity right from its version 3.0. As time passed, numerous features were added to this language, making the task of web development much interesting. 

Now that PHP 7 is on the horizon, it is certainly worth to discuss what new features can be expected, though this exercise is speculative in nature. 

PHP 7 Features and changes that are in the Making


php-7-features


PHPNG will become the basis for PHP 7


NG in PHPNG stands for 'next generation'. PHPNG, a new branch of PHP using Zend Engine, aims at improving the performance of PHP language and memory consumption efficiency. Also, code would run faster with JIT engine in PHP 7 dynamically compiling Zend opcodes into native machine code. 

Combined Comparison Operators


It is also called by the name Spaceship Operator. It serves in performing 3-way comparisons from two operands. < = > operator will return 0 in case the values of both sides are same, will Return 1 in case the value on the left is greater, will Return -1 in case the value on the right is greater.

Scalar Type Declarations


Scalar Type Declarations will make way to use integers, strings, floats and booleans as type declarations. It has to be noted that scalar type declarations are non-restrictive. So, passing a float value to integer parameter will simply coerce it to int with no warnings or errors getting generated. 

Nevertheless, in case a wrong type is passed as an argument, errors can be thrown by enabling strict mode. For enabling strict mode, declare() directive has to be placed at the file top. 

Return Type Declarations


With the coming of PHP 7, the PHP developer can have the flexibility to define the return type of functions and methods. The return type declarations would also work in coercion mode and strict mode, same as in the case of Scalar Type Declarations. 

Uniform Variable Syntax


Variable operators in the yet to be released PHP 7 obtain wider orthogonality. Unlike in the rest of PHP versions, it is possible to have a new operator combinations. The flexibility of combining variable operators arbitrarily is allowed.

Added to the above mentioned, PHP 7 will offer consistent 64-bit support, Anonymous class support, Isset Ternary Operator, Abstract syntax tree, null coalesce operator, lots of libraries, generator return expressions, generator delegation, and so on. 

Conclusion


No doubt, after the release of Version 7, PHP web development will get a shot in the arm. For developers, the sheer pleasure of working on PHP will only see an upward trend. As PHP 7 would be released anytime during the fourth quarter of 2015, you should till then continue with the preceding version of PHP, i.e., PHP 5.
