[SOLVED] convert decimal (?) to time

[gusaps]

Hi...

 

I'm programing something like this... (I'm really a beginner on PHP)

 

http://www.airrouting.com/content/TimeDistanceForm.aspx

 

I have already most of the code on my PHP...

 

but when come to the simplest I cannot find the answer...

 

after the time duration:

 

$duration = $distNM / 400; // distance in nautical miles / per 400 knots average speed

 

I need to show the time in a nice way... like HH:MM, and I cannot find the way to convert the decimals from the formula to time... I guess must be an easy way on the date & time functions but i cannot find it...

 

I need some help on this...

 

Thanks in advance...

I cannot find the way to convert the decimals from the formula to time

 

From that I can't really understand in what format your time currently is. An example would be great.

hi Orio, thanks for your interest.... I see what u mean...

 

The result I get is in hours... because 400 knots per hour is how i measure the speed on the equation... is about 740km/h or 460miles/h

 

Is that what you need?

 

thanks

So what you're getting is something like "5.8641 Hours" and you want to convert it into "5 Hours + X minutes" ?

This should do:

 

<?php

$num_hours = 5.8641; //some float
$hours = floor($num_hours);
$mins = round(($num_hours - $hours) * 60);
echo $hours." Hours and ".$mins." minutes";

?>
