What are some best practices for handling and accessing data in PHP arrays with varying key-value pairs?

When working with PHP arrays that have varying key-value pairs, it's important to use functions that can handle this variability effectively. One common approach is to use functions like `array_key_exists()` or `isset()` to check if a key exists before accessing its value. Another approach is to loop through the array using `foreach` and handle the key-value pairs dynamically. 

// Example of handling and accessing data in PHP arrays with varying key-value pairs

$data = [
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'john.doe@example.com'
];

// Check if a key exists before accessing its value
if (array_key_exists('name', $data)) {
    echo $data['name'];
}

// Loop through the array and handle key-value pairs dynamically
foreach ($data as $key => $value) {
    echo $key . ': ' . $value . '<br>';
}
