Split a string separated with spaces to an array in PHP

Use the explode() function.

$array = explode(" ", $yourVariable);

Example:

Let’s say we have some color names separated with spaces. To convert them to the array, we should use the explode() function, as it is presented in the following example:

<?php

$colors = "red green blue";
$array = explode(" ", $colors);

var_dump($array);

?>
