How can utilizing JSON encoding in PHP improve the readability and usability of data structures like arrays when handling complex database queries?

Utilizing JSON encoding in PHP can improve the readability and usability of data structures like arrays when handling complex database queries by converting the array into a JSON string. JSON is a lightweight data interchange format that is easy for humans to read and write, making it easier to understand the structure of the data being passed around in the code. 

// Sample code demonstrating the use of JSON encoding with PHP arrays
$data = array(
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'johndoe@example.com'
);

// Encode the array into a JSON string
$json_data = json_encode($data);

// Output the JSON string
echo $json_data;
