I have a datetime that I pulled from the database that looks like this: 2000-01-01 08:00:00
Now I need to convert it so all I have left is: 08:00:00
What is the best way to do this?
回答1:
substr('2000-01-01 08:00:00', 11);
回答2:
You could use
substr($timestamp, -8);
回答3:
you can also use the php strtotime function to turn it into a datetime object, then use the format method on it to get a pretty representation however you want. That way you can put in am/pm, do 24 hour or 12 hour, do whatever you want with the date, etc.
$date = strtotime('2000-01-01 08:00:00');
echo $date->format('H:i:s');

I should have thought of this earlier...easiest way would be to use the MySQL TIME() function to only select the time in the first place.
