How can one determine when 24 hours have passed in a PHP application to trigger the update for training durations?

To determine when 24 hours have passed in a PHP application to trigger the update for training durations, you can store a timestamp of the last update in a database or a file. Then, compare the current time with the stored timestamp to check if 24 hours have elapsed. If so, trigger the update for training durations. 

// Retrieve the last update timestamp from the database or a file
$lastUpdateTimestamp = // Retrieve the timestamp from the database or file

// Get the current timestamp
$currentTimestamp = time();

// Calculate the difference in hours
$hoursPassed = ($currentTimestamp - $lastUpdateTimestamp) / 3600;

// Check if 24 hours have passed
if ($hoursPassed >= 24) {
    // Trigger the update for training durations
    updateTrainingDurations();

    // Update the last update timestamp to the current timestamp
    $lastUpdateTimestamp = $currentTimestamp;
    // Save the updated timestamp back to the database or file
}
