如何从mysql PDO选择查询中的时间戳中仅选择时间？

Question

As it currently stands the code below only prints out the complete time stamp as in "2016-03-31 13:22:06" but i would only like to select the time only so "13:22:06" or even just the "13:22".

Just wanted to know how to split these up within a PDO select statement to only grab the time.

Thanks for your help in advance.

/*** The SQL SELECT statement ***/

$sql = "SELECT * FROM chatLogTwo";
foreach ($dbh->query($sql) as $row)
{
 print $row['time'] .' - '. $row['message'] . '<br />';
}

Answer 1

You can try with date() & strtotime() -

print date('H:i:s', strtotime($row['time'])) .' - '. $row['message'] . '<br />';

date() & strtotime()

Or change the query -

"SELECT DATE_FORMAT(`time`, '%H:%i:%s') `time`, message FROM chatLogTwo"

DATE_FORMAT()

Answer 2

你也可以试试这个：

Select DATE_FORMAT(timecol,"%h:%i") AS time FROM chatLogTwo

Answer 3

Instead you can simply update your query into something like as

SELECT *,Date_format(`time`,'%H:%i') as only_time FROM chatLogTwo

and simply access it at your PHP code like as

echo $row['only_time'];
