How to get AM/PM from a datetime in PHP

To get the AM/PM value for a given date and time in PHP, you can use the date() function with the a format string. For example:

<?php

$timestamp = time();
$am_pm = date('a', $timestamp);
echo $am_pm;

This will output either "am" or "pm" depending on the current time. The $timestamp variable should contain a Unix timestamp, which is a numerical representation of a specific point in time. You can get the current timestamp using the time() function.

You can also use the DateTime class to get the AM/PM value for a given date and time. For example:

<?php

$datetime = new DateTime();
$am_pm = $datetime->format('a');
echo $am_pm;

This will also output either "am" or "pm" depending on the current time.
