Summary<\/strong>: In this tutorial, you will learn about the PHP spread operator and how to use it effectively, such as merging multiple arrays into a single one.<\/p>\n\n\n\n

Introduction to the PHP spread operator #<\/a><\/h2>\n\n\n\n

PHP 7.4 introduced the spread operator to the array<\/a> expression. PHP uses the three dots (...<\/code>) to denote the spread operator.<\/p>\n\n\n\n

When you prefix an array with the spread operator, PHP will spread array elements in place:<\/p>\n\n\n

...array_var<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
For example:<\/p>\n\n\n
<?php<\/span>\n\n$numbers = [4<\/span>,5<\/span>];\n$scores = [1<\/span>,2<\/span>,3<\/span>, ...$numbers];\n\nprint_r($scores);<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n
Array<\/span>\n(\n    [0<\/span>] => 1<\/span>\n    [1<\/span>] => 2<\/span>\n    [2<\/span>] => 3<\/span>\n    [3<\/span>] => 4<\/span>\n    [4<\/span>] => 5<\/span>\n)<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
