PHP将字符串转换为SQL类型DateTime

Question

I want to be able to compare an input of $date, which is a string, with a value from the database with the type of "datetime". Here's my code below. It outputs as a string type instead of the desired datetime type. Can you please help me out?

<?php
  $string="2013-04-19 14:08:10";
  $timestamp = strtotime($string);
  $date = date("Y-m-d H:i:s", $timestamp);
?>
<?php var_dump($date);?>

this is the output

string '2013-04-19 14:08:10' (length=19)

Thanks so much for your help.

对于MySQL datetime数据类型，可以使用：

$date = new \DateTime('2013-04-19 14:08:10');
