How array destructuring occurs in php

How Array Destructuring Occurs in PHP In today’s technology­driven world, PHP is the world’s most famous and accessible server­side programming language and mainly used to build the dynamic website.

PHP is freely available (open source) language. PHP scripts are executed on the server. Incredibly PHP is powerful enough to be at the core of the most prominent blogging platform on the web (WordPress) and is enough to run the most expensive social network (Facebook).(Note: Hire PHP Developer if you aren’t aware any technical language like PHP.)

Super Powers in PHP 7.1 Array

In PHP 7.1 the array type has become more powerful! An RFC was accepted to provide square bracket syntax for array destructuring assignment. To come with the this changes language made it possible to extract values from array more easily.

For example, Following options array:

<?php $options = ['enabled' => true, 'compression' => 'gzip'];

Let’s assume that, you want to assign the options to variable we could use something like this:

$enabled = $options['enabled']; $compression = $options['compression'];

It’s ok but using the features of this new RFC we could have a slightly more expressive way to define this. You might know this kind of expression if you have used ES6’s from of this. let options = {enabled: true, compression: 'gzip'}; let { enabled, compression } = options; Here, in this example, the enabled and compression key are extracted into variables in a language contract that can be viewed as the inverse of the initial options assignment. let { enabled: enabled, compression: compression } = options; The expansion also give permission for renamed and can mixed with the shorter version: let { enabled, compression: algorithm } = options; Version 7.1: we can use these type of syntax in PHP too! $options = ['enabled' => true, 'compression' => 'gzip']; ['enabled' => $enabled, 'compression' => $compression] = $options;

With this example, the value of the enabled key is assigned to the $enabled variable and the same goes for the compression key.

List Assignments Aside from associative destructuring, list destructing is also possible. Here, the question arises that when destructuring useful? Useful when you are using arrays as you would a Tuple. A tuple is the finite ordered list that holds a fixed number of items.

[$a, $b] = [1, 2]; // $a is now 1 // and $b is 2

You are using variables in the source array, so you can effectively swap variable using this syntax: $a = 1; $b = 2; [$a, $b] = [$b, $a]; // $a is now 2 // and $b is 1

I hope you have fun exploring the new possibilities using these techniques!
