PHP compact

Introduction

Compact is one of those functions that helps the readability of your code a lot and also reduces the lines of code you should write.

Compact

Compact gets the name of the variables as argument and then creates an array with name of the variable as the key and the value of the variable as the value of the array element.

So let’s say we have a few variables and we want to create an array from them. Without compact I should do something like this:

$twitter = 'pratham';
$feedhive = 'simon';
$php = 'amir';
$people = [
   'twitter'  => $twitter,
   'feedhive' => $feedhive,
   'php'      => $php,
];

But now thanks to compact I can write this

$people = compact('twitter','feedhive','php');
print_r($people);
// Array (
// [twitter]    => pratham
// [feedhive]   => simon
// [php]        => amir
// )

Isn’t it amazing? Using the compact function is going to help you a lot.
