在php中格式化日期并存储在mysql中

Question

我有此语句可以在mysql中保存日期，但我想将其保存为示例：

September 24, 2011, 6:39 am 。

还是我应该拥有它，而当我检索它时，我会像这样回显它？

try {
      $date = date('Y-m-d H:i:s');
        //insert into database with a prepared statement
        $stmt = $db->prepare('INSERT INTO admin (username, password, email, register_date, active) VALUES (:username, :password, :email, :register_date, :active)');
        $stmt->execute(array(
            ':username' => $_POST['username'],
            ':password' => $hashedpassword,
            ':email' => $_POST['email'],
            ':register_date' => $date,
            ':active' => $activasion
    ));
//else catch the exception and show the error.
        } catch(PDOException $e) {
            $error[] = $e->getMessage();
        }

Answer 1

<?php
/* 
   * F --> for full month
   * D -->day
   * Y --> Year
   * H -->Hour
   * m -->minute
   * A -- PM or AM

*/
$date = date("F d, Y, H:m A");
echo $date;   
?>

输出将是

July 26, 2017, 21:07 PM

Answer 2

// original datetime string:
$str = 'September 24, 2011, 6:39 am';

$stmt->execute(array(
        ':username' => $_POST['username'],
        ':password' => $hashedpassword,
        ':email' => $_POST['email'],
        ':register_date' => strftime("%Y-%m-%d %H:%M:%S", strtotime($str)),
        ':active' => $activasion
));

日期格式为： 2011-09-24 06:39:00 ： 2011-09-24 06:39:00 ： 2011-09-24 06:39:00 ，MySQL会很高兴。
