Are there any best practices to follow when passing multiple variables in a PHP file for better code readability and maintenance?

When passing multiple variables in a PHP file, it is best practice to use an associative array to improve code readability and maintenance. By grouping related variables together in an array, it makes it easier to manage and pass them around in your code. This approach also helps to avoid passing a long list of individual variables to functions or methods, which can lead to confusion and errors. 

// Define an associative array to store multiple variables
$data = [
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'john.doe@example.com'
];

// Pass the array to a function or method
someFunction($data);

// Access individual variables within the function
function someFunction($data) {
    $name = $data['name'];
    $age = $data['age'];
    $email = $data['email'];
    
    // Use the variables as needed
    echo "Name: $name, Age: $age, Email: $email";
}
