How can the output format of an array be customized for better readability in PHP?

When outputting an array in PHP, the default format may not always be the most readable. To customize the output format for better readability, you can use functions like print_r() or var_export() to display the array in a more structured and organized way. Additionally, you can iterate through the array and format the output as needed. 

// Example of customizing the output format of an array for better readability
$array = [1, 2, 3, 4, 5];

// Using print_r() function
echo '<pre>';
print_r($array);
echo '</pre>';

// Using var_export() function
echo '<pre>';
var_export($array);
echo '</pre>';

// Iterating through the array and formatting the output
echo '<ul>';
foreach ($array as $value) {
    echo '<li>' . $value . '</li>';
}
echo '</ul>';
