How to check if an Array is Not Empty in PHP ?

In PHP, you can use the empty function or check the array's length to determine if it's not empty.

In this example,

We check if the array is not empty using the empty function or by checking its length, and store the result in the variable $notEmpty.
Finally, we echo whether the array is not empty or not.

<?php
$numbers = [1, 2, 3];
$notEmpty = !empty($numbers) || count($numbers) > 0;
echo 'Array is not empty: ' . ($notEmpty ? 'true' : 'false');
?>
