time difference

[matthew9090]

i have searched everywhere and no code seems to work. i have time1 and time 2 in the format Y-m-d H:i:s. i just don't know how to find the difference.

 

old time: 2011-04-11 20:15:46

 

new time: 2011-04-11 21:00:11

 

after i have the difference, i need to get a resource production per hour which is stored in the database and calculate the new value of the resource.

 

$production_per_hour = 100;
$time_old = "2011-04-11 20:15:46";
$time_new = "2011-04-11 21:00:11";
$current_resources = "500";

echo strtotime($new_time) - strtotime($old_time);

Will give you the difference in seconds.  Some simple math to get days, hours, minutes, etc.

i hav almost got it working. i just need the right formula.

 

$calculate = $difference / 60 + $production + $current_resources;

$round = round($calculate, 0);

 

that is what i made up but i think it is wrong
