HTML5 and MySQL date format

Question

I am unable to insert HTML5 default date format(mm/dd/yyyy) in mysql(YYYY-mm-dd).Please help is there any way to insert the html5 date into mysql. Or is it possible to change the html5/mysql date format?

<?php
  $name=$_POST['name'];
  $email=$_POST['email'];
  $password=$_POST['password'];
  $gender=$_POST['gender'];
  $bday=$_POST['bday'];
  include('connect.php');
  $y=mysql_query("insert into users values('$name','$email','$password','$gender','$bday')");
?>

Answer 1

<?php

$date = date('Y-m-d',strtotime($date));

?>
