The following example illustrates how to calculate working days excluding week end days.

<?

function count_woking_days($date_start,$date_end){

$workdays = 5;

$firstdate = strtotime($date_start);

$lastdate = strtotime($date_end);

//get the day of the date

$firstday = date(w,$firstdate);

$lastday = date(w,$lastdate);

//get the week of the date

$firstweek = date(W,$firstdate);

$lastweek = date(W,$lastdate);

if($lastday > $workdays){

$lastday = $workdays;

}

if($lastday >= $firstday){

$leftday = $lastday - $firstday;

}else{

$leftday = $firstday - $lastday;

}

$diffweeks = $lastweek - $firstweek;

$dayinweeks = $diffweeks * $workdays;

return $totaldays = $dayinweeks + $leftday + 1;

}

$from_date = “2007-02-14″;

$to_date = “2007-02-28″;

echo count_woking_days($from_date,$to_date);

?>

In above example we can pass starting and ending date to “count_working_days()” function. In that funtion, we can calculate the totaldays except week end days.
