How to convert the time from AM/PM to 24 hour format in PHP?

Question

For example, I have a time in this format:

eg. 

09:15 AM
04:25 PM
11:25 AM

How do I convert it to :

09:15
16:25
23:25


        

Answer 1

You can use this for 24 hour to 12 hour:

echo date("h:i", strtotime($time));

And for vice versa:

echo date("H:i", strtotime($time));

Answer 2

If you use a Datetime format see http://php.net/manual/en/datetime.format.php

You can do this :

$date = new \DateTime();
echo date_format($date, 'Y-m-d H:i:s');
#output: 2012-03-24 17:45:12

echo date_format($date, 'G:ia');
#output: 05:45pm

Answer 3

We can use Carbon

 $time = '09:15 PM';
 $s=Carbon::parse($time);
 echo $military_time =$s->format('G:i');

Answer 4

$Hour1 = "09:00 am";
$Hour =  date("H:i", strtotime($Hour1));  

Answer 5

PHP 5.3+ solution.

$new_time = DateTime::createFromFormat('h:i A', '01:00 PM');
$time_24 = $new_time->format('H:i:s');

Output: 13:00:00

Works great when formatting date is required. Check This Answer for details.
