PHP Spread Syntax in Array Declaration

Question

PHP supports the spread syntax for variadic functions.

In JavaScript, you can use the spread syntax to do this:

var a = [1, 2];
var b = [...a, 3, 4];         


        

Answer 1

In PHP 7.4 you can now use Spread Operators in array expressions.

$parts = ['apple', 'pear'];
$fruits = ['banana', 'orange', ...$parts, 'watermelon'];
// ['banana', 'orange', 'apple', 'pear', 'watermelon'];
