time conversion

Hi people

If somebody gives you a total number of seconds, for example 1890 seconds, what is the best way to convert this into total number of hours, minutes and seconds?

Thanks!

ill just throw up some psuedocode of what i think would be the best way todo this

first off have a form unless its a set time you are converting but in that case why convert it just write the answers, i dont know what you are doing so here lol

on the form have a text field called "secinput" or whatever you want

then

PHP Code:


		
			
 $seconds = "$secinput";

echo($seconds);



$minutes = "$secinput / 60";

echo($minutes);



$hours = "$secinput / 60 / 60";

echo($hours);



$days = "$secinput / 60 / 60 / 24";

echo($days);

like i said its just some pseudocode ideas, i dont even know if thats how you do calculations in php im just a noob and i dont know what exactly you want todo but since no one else responded i thought i would. also you will get decimal answers with the method i showed.

good luck

Just make it separate:

$days = floor($secinput / 60 / 60 / 24);
$hours = floor(($secinput -$days*60*60*24)/ 60 / 60);
...etc..

echo"$days-$hours-$minutes-$seconds";

this worked quite well for me, although the way that serg4444 suggests looks better:

PHP Code:


		
			
if($seconds < 86400) 

{ 

   $day = 0; 

}else{ 

   $day = floor($seconds / 86400); 

   $seconds -= 86400*$day; 

} 



if($seconds < 3600) 

{ 

   $hours = 0; 

}else{ 

   $hours = floor($seconds / 3600); 

   $seconds -= 3600*$hours; 

} 



if($seconds < 60) 

{ 

   $minutes = 0; 

}else{ 

   $minutes = floor($seconds / 60); 

   $seconds -= 60*$minutes; 

} 



$uptime = "$day days $hours hours $minute minutes $seconds seconds";
