How can PHP be used to handle time-based database operations effectively?

To handle time-based database operations effectively in PHP, you can use functions like `strtotime()` to convert date/time strings into timestamps and compare them against the current time using `time()`. This allows you to easily query and update database records based on specific time conditions.

// Example code to handle time-based database operations
$current_time = time();
$target_time = strtotime("2023-01-01 00:00:00");

if ($current_time >= $target_time) {
    // Perform database operation based on time condition
    // For example, update a record or retrieve data
    // $query = "UPDATE table SET column = value WHERE condition";
    // $result = mysqli_query($connection, $query);
}
