What are some strategies for efficiently checking for event conflicts in PHP?

When checking for event conflicts in PHP, one efficient strategy is to loop through each event and compare their start and end times with the start and end times of the new event being added. If there is any overlap in the time range, then a conflict exists. Another strategy is to use a database query to check if there are any events already scheduled during the same time period. 

// Assuming $newEventStart and $newEventEnd are the start and end times of the new event being added
// Assuming $events is an array of existing events with 'start' and 'end' keys

$conflict = false;

foreach ($events as $event) {
    if (($newEventStart >= $event['start'] && $newEventStart < $event['end']) || 
        ($newEventEnd > $event['start'] && $newEventEnd <= $event['end']) ||
        ($newEventStart <= $event['start'] && $newEventEnd >= $event['end'])) {
        $conflict = true;
        break;
    }
}

if ($conflict) {
    echo "Event conflict detected!";
} else {
    echo "No conflict found. Event can be added.";
}
