You can use the PHP array_filter() function to remove or filter empty or false values from an array.

Let’s take a look at an example:
<?php
$array = array("apple", "", 2, null, -5, "orange", 10, false, "");
var_dump($array);
echo "<br>";
// Filtering the array
$result = array_filter($array);
var_dump($result);
