Answer 1

use MySQL DATE_FORMAT

DATE_FORMAT(pubdate,'%Y-%m-%d %h:%i %p')

You query like that :-

$sql = "select id,firstname,lastname,
DATE_FORMAT(pubdate,'%Y-%m-%d %h:%i %p') as pubdate from student";

Answer 2

i think you can use :

echo date('Y-m-d h:i:s', strtotime($row['pubdate']));

Live Sample

h is used for 12 digit time
i stands for minutes
s seconds
a will return am or pm (use in uppercase for AM PM)
m is used for months with digits
d is used for days in digit
Y uppercase is used for 4 digit year (use it lowercase for two digit)

Answer 3

要将日期转换为上午12点，请使用

echo date('h:i:s a m/d/Y', strtotime($row['pubdate']));

Answer 4

Use date() and strtotime() of PHP:

echo date("Y-m-d h:i:s A", strtotime($row["pubdate"])); /* WILL ECHO 2015-11-10 02:50:24 PM */

Refer here for more date format.

Answer 5

使用date（）和strtotime（）函数

echo date("Y-m-d h:i:s A", strtotime($row["pubdate"]));
