[SOLVED] Call function inside another function

[craygo]

I have a function that gives me the difference between 2 dates. I also have another function which compares a couple things and uses the first function. How do I call one function from within another. Here are the 2 functions.

<?php
function datediff($interval, $datefrom, $dateto, $using_timestamps = false) {
  /*
    $interval can be:
    yyyy - Number of full years
    q - Number of full quarters
    m - Number of full months
    y - Difference between day numbers
      (eg 1st Jan 2004 is "1", the first day. 2nd Feb 2003 is "33". The datediff is "-32".)
    d - Number of full days
    w - Number of full weekdays
    ww - Number of full weeks
    h - Number of full hours
    n - Number of full minutes
    s - Number of full seconds (default)
  */

  if (!$using_timestamps) {
    $datefrom = strtotime($datefrom, 0);
    $dateto = strtotime($dateto, 0);
  }
  $difference = $dateto - $datefrom; // Difference in seconds

  switch($interval) {

    case 'yyyy': // Number of full years

      $years_difference = floor($difference / 31536000);
      if (mktime(date("H", $datefrom), date("i", $datefrom), date("s", $datefrom), date("n", $datefrom), date("j", $datefrom), date("Y", $datefrom)+$years_difference) > $dateto) {
        $years_difference--;
      }
      if (mktime(date("H", $dateto), date("i", $dateto), date("s", $dateto), date("n", $dateto), date("j", $dateto), date("Y", $dateto)-($years_difference+1)) > $datefrom) {
        $years_difference++;
      }
      $datediff = $years_difference;
      break;

    case "q": // Number of full quarters

      $quarters_difference = floor($difference / 8035200);
      while (mktime(date("H", $datefrom), date("i", $datefrom), date("s", $datefrom), date("n", $datefrom)+($quarters_difference*3), date("j", $dateto), date("Y", $datefrom)) < $dateto) {
        $months_difference++;
      }
      $quarters_difference--;
      $datediff = $quarters_difference;
      break;

    case "m": // Number of full months

      $months_difference = floor($difference / 2678400);
      while (mktime(date("H", $datefrom), date("i", $datefrom), date("s", $datefrom), date("n", $datefrom)+($months_difference), date("j", $dateto), date("Y", $datefrom)) < $dateto) {
        $months_difference++;
      }
      $months_difference--;
      $datediff = $months_difference;
      break;

    case 'y': // Difference between day numbers

      $datediff = date("z", $dateto) - date("z", $datefrom);
      break;

    case "d": // Number of full days

      $datediff = floor($difference / 86400);
      break;

    case "w": // Number of full weekdays

      $days_difference = floor($difference / 86400);
      $weeks_difference = floor($days_difference / 7); // Complete weeks
      $first_day = date("w", $datefrom);
      $days_remainder = floor($days_difference % 7);
      $odd_days = $first_day + $days_remainder; // Do we have a Saturday or Sunday in the remainder?
      if ($odd_days > 7) { // Sunday
        $days_remainder--;
      }
      if ($odd_days > 6) { // Saturday
        $days_remainder--;
      }
      $datediff = ($weeks_difference * 5) + $days_remainder;
      break;

    case "ww": // Number of full weeks

      $datediff = floor($difference / 604800);
      break;

    case "h": // Number of full hours

      $datediff = floor($difference / 3600);
      break;

    case "n": // Number of full minutes

      $datediff = floor($difference / 60);
      break;

    default: // Number of full seconds (default)

      $datediff = $difference;
      break;
  }

  return $datediff;

}
function gametime($now, $lastgame){
         $gt = array();
         $game_time_dif = ($now - $lastgame);

          if($game_time_dif < 3601){
          $gt[0] = "mins ago";
          $gt[1] = abs(datediff('n', $now, $lastgame, true));
          } else {
            if($game_time_dif > 3600 && $game_time_dif < 86400){
              $gt[0] = "hrs ago";
              $gt[1] = abs(datediff('h', $now, $lastgame, true));
            } else {
            $gt[0] = "days ago";
            $gt[1] = abs(datediff('d', $now, $lastgame, true));
            }
          }
          if($gt[1] > 9 && $gt[0] == "days ago"){
          $gt[2] = "<font color=red>";
          } else {
          $gt[2] = "<font color=black>";
          }
return $gt;
}
?>

 

thanks for the help

Im not sure i understand what the problem is. As far as i can see, the functions work. If i use:

 

<?php
$gt = gametime(3600,3540);
echo $gt[1].' '.$gt[0];
?>

 

After having defined your functions, then i get the output 1 mins ago, which i presume is the correct output.

 

Do you think you could explain a bit more?

Jesus I got to be a retard. Thanks for the quick reply ginger. I forgot to store the function in a variable.

 

i use

gametime($now, $last_game);

$gdiff = $gt[0];

 

instead of

$gt = gametime($now, $last_game);

$gdiff = $gt[0];

 

 

thanks for slapping me across the head!!!

Haha, no worries. Always the simple little bits that catch you out
