How to get AM/PM from a datetime in PHP

You need to convert it to a UNIX timestamp (using strtotime) and then back into the format you require using the date function.

For example:

$currentDateTime = '08/04/2010 22:15:00';
$newDateTime = date('h:i A', strtotime($currentDateTime));

$dateString = '08/04/2010 22:15:00';
$dateObject = new DateTime($dateString);
echo $dateObject->format('h:i A');

Use strtotime() to make the date a UNIX timestamp.

For output, check out the various options of date().

$timestamp = strtotime("08/04/2010 22:15:00");
date("h.i A", $timestamp);
