PHP strtotime 不求和

Question

Hello i'm using this code to make a test.

 <?php echo date("H:i:s", strtotime('00:00:10') + strtotime('00:00:10')); ?>

But the output is '15:32:04' instead of '00:00:20' and i cannot find the solution.

I also try:

<?php echo gmdate("H:i:s", strtotime('00:00:10') + strtotime('00:00:10')); ?>

and give me the same output.

Thanks for help

You should be using the dateTime class: http://php.net/manual/en/class.datetime.php

It's a lot simpler once you start using it and you can do almost anything you'd like by calling a function. for example you can add X time to a date object by calling the add function: http://php.net/manual/en/datetime.add.php

Bear in mind this class will only exist for you if you have php 5.3 or higher.
