RE: [PHP] workdays - CODE From: Bravo, David (CORP, MTC) (David.Bravo <email protected>)
Date: 11/15/00

Finally I wrote this code that shows the difference between two dates
without Saturdays and Sundays...
Additions/corrections will be appreciated... (i would like to include
holidays feature)
Regards

// Code by elbuenchubi

// gpled

// define dates
$month1=11;
$day1=30;
$year1=2000;

$month2=12;
$day2=6;
$year2=2000;

$days=0;

// get timestamp
$date1=mktime($hour1,$minute1,$second1,$month1,$day1,$year1);
$date2=mktime($hour2,$minute2,$second2,$month2,$day2,$year2);

// get week day number
$dayofweek1=date(w,$date1);
$dayofweek2=date(w,$date2);

// calculates the weeks difference between the dates
$diff_in_secs=$date2 - $date1;
$diff_in_days=$diff_in_secs / 86400;
$diff_in_weeks=$diff_in_days /7;
$diff_in_weeks=floor($diff_in_weeks);

// add remaining days
if ($dayofweek1<$dayofweek2)
  {
   $days=$dayofweek2-$dayofweek1;
   if ($dayofweek2==6) $days=$days-1;
  }

if ($dayofweek1>$dayofweek2)
  {
   if ($dayofweek1<>'6')
     {
      $days=5-$dayofweek1+$dayofweek2;
     } else {
      $days=$dayofweek2;
     }
  }

// calculate days difference without Saturdays and Sundays
$workdays=($diff_in_weeks*5)+($days);

// get Fiscalweek number (doesn't afect the code purpose)
$fiscalweek1=strftime ("%V", $date1);
$fiscalweek2=strftime ("%V", $date2);

// show results

echo "=".$diff_in_days." dias de diferencia, <br>";
echo "=".$diff_in_weeks." semanas <br>";
echo "=".$workdays." días laborales, <br>";
echo "entre el ".date('m/d/Y',$date1)." <i>(FW".$fiscalweek1.")</i> y el
".date('m/d/Y',$date2)." <i>(FW".$fiscalweek2.")</i><br>";
