Adding time intervals

[php_novice2007]

Hi,

 

If I have a mysql timestamp string, and I have another variable which stores a number in minutes, how can I add it to my string?

 

eg1. $current = 2007-02-26 12:32:06, $add = 6

So I want the result to be $res = 2007-02-26 12:38:06

 

eg2. $current = 2007-03-01 12:53:02, $add = 120

So result expected = 2007-03-01 14:53:02

 

eg3. $curent = 2007-03-05 23:15:24, $add = 150

Want result to be = 2007-03-06 01:45:24

 

Would I have to manually chop up the current string, add numbers to that, check for carry over either into the hour or to the next day? Is there an easier way?

 

Thanks~!

Take a look at the examples for the date function.

Whats wrong with my code?

 

<?php
  date_default_timezone_set("Australia/NSW"); 
  echo "Today is " . date("Y-m-d H:i:s")."<br>";
  $makeup = date("Y-m-d H:i:s", mktime(14,38,13,2,7,2007));
  echo "Make up date is ". $makeup;
  echo "<br>";
  echo "Make up date + 150 minutes is";
  echo "<br>";
  $makeupNext = date("Y-m-d H:i:s", mktime(14,38,13,2,7,2007)) + (150*60);
  $makeupNextActual = date("Y-m-d H:i:s", $makeupNext);
  echo $makeupNextActual;
?>

 

The output I get is

 

Today is 2007-03-23 09:54:45

Make up date is 2007-02-07 14:38:13

Make up date + 150 minutes is

1970-01-01 13:03:27

 

I want $makeupNextActual = 2007-02-07 17:08:13, if I just print out $makeupNext I get 11007

 

I'm lost...
