Make Time look correct in php

[beginneratphp]

Hi,

 

I have the following function:

 

function hourstodecimal ($timeinhours) {
  $timeparts = explode(':', $timeinhours);
  return ($timeparts[0] + ($timeparts[1]/60));
}

function decimaltohours ($timeindecimal) {
  $hours = floor($timeindecimal);
  $minutes = str_pad( (($timeindecimal - $hours)*60), 2, '0');
  return $hours.':'.$minutes;
}

 

however, if i display 10hours and 4 (anything below 10) minutes it looks like: 10:4

 

and sometimes if i enter something like 10hours 43 minutes it will look like: 10:43.254221

 

how could i make the time to 2 decimal places like it should be and when it is below 10 it sticks a 0 infront of the minute to look correct?

 

MANY MANY THANKS in advance!

what are you passing to the functions?

Are you aware of the time() and date() functions?

Passing decimal from DB thru function so it replies with a time.

I am just curious about why you want to display the time in a decimal format.

 

Like phat_hip_prog said, check out the time(), date(), and mktime() functions.

For statistic purposes it is easier for me to keep the time in decimal format in the DB.

[phat_hip_prog]

unix time is easiest (e.g. time()) which is seconds since "Thu, 01 Jan 1970" (why that date I um wonder?), it's also in integer format and you can't get easier than that... anyway what do you make your decimal time from?

For general perpose, you can do this (obviously can be cut down to one line, but for demonstration purpose):

 

// the time is 12:04

$h = 12;

$m = 04;

$str_m = $m;

while (strlen($str_m)<2){$str_m = "0".$str_m;}

$t = $h .":".$str_m;
