Extending @nevermind's answer, one can use DateTime::createFromFormat: like,

// use - instead of _. replace _ by - if needed.
$format = "d-m-y";
$date1  = DateTime::createFromFormat($format, date('d-m-y'));
$date2  = DateTime::createFromFormat($format, str_replace("_", "-",$date2));    
var_dump($date1 > $date2);
