What best practices should be followed when modifying PHP code for displaying dynamic information like opening hours?

When modifying PHP code for displaying dynamic information like opening hours, it is best to store the opening hours data in a database or configuration file for easy updating. Use PHP functions to retrieve the opening hours data and display it dynamically on the website. Ensure that the code is properly structured and commented for easy maintenance and future updates. 

// Retrieve opening hours data from a database or configuration file
$openingHours = [
    'Monday' => '9:00 AM - 5:00 PM',
    'Tuesday' => '9:00 AM - 5:00 PM',
    'Wednesday' => '9:00 AM - 5:00 PM',
    'Thursday' => '9:00 AM - 5:00 PM',
    'Friday' => '9:00 AM - 5:00 PM',
    'Saturday' => '10:00 AM - 3:00 PM',
    'Sunday' => 'Closed'
];

// Display opening hours dynamically
foreach ($openingHours as $day => $hours) {
    echo $day . ': ' . $hours . '<br>';
}
