    $date1 = new DateTime();

    echo $date1->getTimestamp();
    echo $date2->getTimestamp();

Answer 1

MySQL 有一个内置函数用于调用UNIX_TIMESTAMP

SELECT UNIX_TIMESTAMP(NOW())

• SQLFiddle 演示
• UNIX_TIMESTAMP

更新

$sql = "SELECT *,UNIX_TIMESTAMP(dateTime) unx FROM temp_user";
$result = mysql_query($sql);
while ($row = mysql_fetch_assoc($result)) 
{
    $var = $row['unx'];
    // other codes
}
