How to Compare DateTime Objects in PHP 5.2.8?

Comparing DateTime Objects in PHP 5.2.8

PHP 5.2.8 provides two methods for comparing DateTime objects:

• Comparison operators: The standard comparison operators (==, !=, >, <, >=, <=) can be used directly on DateTime objects to compare their dates and times.

$date1 = new DateTime('2023-03-10 15:30:00');
$date2 = new DateTime('2023-03-10 16:00:00');

if ($date1 < $date2) {
  echo 'Date 1 is earlier than Date 2.' . PHP_EOL;
}

• getTimestamp() method: Alternatively, you can call the getTimestamp() method on each object and compare the resulting Unix timestamps.

$timestamp1 = $date1->getTimestamp();
$timestamp2 = $date2->getTimestamp();

if ($timestamp1 < $timestamp2) {
  echo 'Date 1 is earlier than Date 2.' . PHP_EOL;
}
