What are best practices for handling date and time comparisons in PHP and MySQL?

When comparing dates and times in PHP and MySQL, it's important to ensure that the formats match and that time zones are taken into account. One common approach is to use the DateTime class in PHP to create DateTime objects for comparison. Additionally, when storing dates and times in MySQL, it's recommended to use the DATETIME data type for accurate storage and retrieval. 

// Example of comparing dates in PHP using DateTime objects
$date1 = new DateTime('2022-01-01');
$date2 = new DateTime('2022-01-15');

if ($date1 < $date2) {
    echo "Date 1 is before Date 2";
} else {
    echo "Date 2 is before Date 1";
}
