以不同格式比较php中的日期

Question

PHP 5.3.3.

$olddate = '2014-04-30';
$newdate = '30/05/2014';

Is there a simple way to compare these dates (which one is more recent) without having to manipulate the strings or changing one strings format?

I'm looking for a one or two liner?

Answer 1

You can not compare values as string.

You can use \DateTime object or convert this times to integer (timestamp), and next compare.

$oldDate = \DateTime::createFromFormat('Y-m-d', $oldDate);
$newDate = \DateTime::createFromFormat('d/m/Y', $newDate);

if ($newDate > $oldDate) {
  // Your action
} else {
  // Your action
}
