This tutorial offers step-by-step guidance, illustrating two different methods to check if an array is empty using PHP functions. By the end, you'll be equipped with the knowledge to efficiently handle empty arrays in your PHP projects.

Method 1: Using the empty() Function

    $array = [];
  
    if (empty($array)) {
        echo('The array is empty.');
    } else {
        echo('The array is not empty.');
    }
  
?>

Output:

The array is empty.

Method 2: Using the count() Function

<?php
  
    $array = [];
  
    if (count($array) === 0) {
        echo('The array is empty.');
    } else {
        echo('The array is not empty.');
    }

These examples demonstrate how to effectively check whether an array is empty using PHP. Whether you prefer the simplicity of the empty() function or the explicitness of comparing the count to zero, these methods ensure you can handle empty arrays with ease in your PHP applications.
