What are some best practices for formatting and outputting arrays in PHP?

When outputting arrays in PHP, it is important to format them in a readable and organized manner for better understanding. One common way to achieve this is by using the `print_r()` or `var_dump()` functions to display the array's structure and values. Additionally, you can iterate through the array using a loop and format the output as needed. 

// Example of formatting and outputting an array in PHP
$array = array('apple', 'banana', 'cherry');

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

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

// Using a loop to format the array output
echo '<ul>';
foreach ($array as $item) {
    echo '<li>' . $item . '</li>';
}
echo '</ul>';
