php - Check if date isn't greater than today -

i want check if date isn't greater today. write code isn't work:

public function getdate() {     $month = $this->month;     return $this->year . '-' . $month . '-' . $this->day; }  public function getdbformateddate() {     if (checkdate($this->month, $this->day, $this->year) || $this->strtotime(getdate())>strtotime(date("y-m-d"))){         $datedeadline    = date_create($this->getdate());         $this->birthdate = date_format($datedeadline, 'y-m-d');          yii::$app->session->setflash('success', yii::t('app', 'zmiany w profilu zostały zapisane'));     } else {         yii::$app->getsession()->setflash('error', 'nie ma takeij daty');     } } 

use curdate() + interval 2 day

select * `table` date > curdate() + interval 2 day 

this should trick!
