What are some best practices for efficiently iterating through JSON data in PHP and applying conditional styling based on value types?

When iterating through JSON data in PHP, it is important to efficiently parse the data and apply conditional styling based on the value types. One approach is to use the `json_decode()` function to convert the JSON data into a PHP array, and then use a recursive function to iterate through the array elements. Within the recursive function, you can check the data types of the values and apply conditional styling accordingly. 

<?php
// Sample JSON data
$json_data = '{"name": "John Doe", "age": 30, "is_active": true, "email": "john@example.com"}';

// Convert JSON data to PHP array
$data = json_decode($json_data, true);

// Recursive function to iterate through array elements
function iterateArray($array) {
    foreach ($array as $key => $value) {
        if (is_array($value)) {
            iterateArray($value);
        } else {
            // Apply conditional styling based on value types
            if (is_int($value)) {
                echo "<p>{$key}: <span style='color: blue;'>{$value}</span></p>";
            } elseif (is_bool($value)) {
                echo "<p>{$key}: <span style='color: green;'>".($value ? 'true' : 'false')."</span></p>";
            } else {
                echo "<p>{$key}: <span style='color: red;'>{$value}</span></p>";
            }
        }
    }
}

// Call the recursive function with the JSON data array
iterateArray($data);
?>
