What are the best practices for handling overlapping time intervals in PHP scripts to accurately determine a business's open or closed status?

When determining a business's open or closed status based on overlapping time intervals, it is important to accurately handle the logic to avoid any discrepancies. One way to achieve this is by creating a function that checks if the current time falls within any of the defined time intervals for the business's operating hours. 

function isBusinessOpen($openHours) {
    $currentTime = new DateTime();
    $currentDay = $currentTime->format('D');
    
    foreach ($openHours[$currentDay] as $interval) {
        $startTime = DateTime::createFromFormat('H:i', $interval['start']);
        $endTime = DateTime::createFromFormat('H:i', $interval['end']);
        
        if ($currentTime >= $startTime && $currentTime < $endTime) {
            return true;
        }
    }
    
    return false;
}

// Define the business's operating hours
$openHours = [
    'Mon' => [
        ['start' => '09:00', 'end' => '17:00']
    ],
    'Tue' => [
        ['start' => '09:00', 'end' => '17:00']
    ],
    // Add the rest of the days and intervals here
];

// Check if the business is open
if (isBusinessOpen($openHours)) {
    echo 'The business is open.';
} else {
    echo 'The business is closed.';
}
