This is a quick function to calculate the "working days" within a period of one year.
"Working days" are those without weekends and without the holidays specified in the
$holiday array. I left for the reader its implementation for more than 1 year.
<?php
/*
* Author: Alberto Lepe
* Calculates the working days from today to an specific date.
* NOTE: counting starts from today
* @pararm to_date: timestamp
*/
function get_working_days($to_date) {
$holidays = array(
1 => array(10), //2011 ...
2 => array(11),
3 => array(21), //... 2011
4 => array(29,30), //2010 ...
5 => array(3,4,5),
6 => array(),
7 => array(19),
8 => array(11,12,13),
9 => array(20,23),
10 => array(11),
11 => array(3,23),
12 => array(23) //... 2010
);
for($to_date, $w = 0, $i = 0, $x = time(); $x < $to_date; $i++, $x = strtotime("+$i
day")) {
if(date("N",$x) < 6 &!
in_array(date("j",$x),$holidays[date("n",$x)])) $w++;
}
return $w;
}
//Usage:
echo get_working_days(strtotime("2011-01-08"));
?>
