When updating code for clarity, is it advisable to modify placeholders like %title to match the corresponding array key?

When updating code for clarity, it is advisable to modify placeholders like %title to match the corresponding array key for better readability and maintainability. By using descriptive array keys that match the data being accessed, it becomes easier for other developers to understand the code and make changes in the future. This practice also helps prevent confusion and errors when working with arrays.

// Before updating code
$data = [
    'title' => 'Hello, World!',
    'content' => 'This is some sample content.'
];

echo sprintf('Title: %s', $data['title']);

// After updating code
$data = [
    'title' => 'Hello, World!',
    'content' => 'This is some sample content.'
];

echo sprintf('Title: %s', $data['title']);
