I must be bored:
for($next = strtotime('-30 days');
$next <= strtotime('+30 days');
$next = strtotime('Next Friday', $next))
{
echo date("F j, Y", $next)."\n";
}

Lots of ways to skin that cat, here is one:
$date = time(); //or whenever
$start = strtotime('-30 days', $date);
$end = strtotime('+30 days', $date);
$next = $start;
while(($next = strtotime('Next Friday', $next)) <= $end) {
echo date("F j, Y", $next)."\n";

[PHP] Re: Calendar math .... how to count in week days....?
The PEAR functions didn't seem to do what I was looking for. I built this
function based on an idea given to me by Daryl Meese.
After much trial and error, it actualy does what I need. My function is
bassed on hours but you can easily change that. It will add or subtract
days.
- Anthony
/* buisinessDays
* Calculates a new date bassed on buisiness hours
* vars: hours to adjust by, timestamp
* returns: adjusted timestamp
*/
function businessDays($hours,$date) {
// this function assumes $date is a business day
$dayHours=7.5; // set how many hours are in a day
// set the days we need to adjust by. there is a one day buffer
$days=(abs($hours/$dayHours))+1;
// weeks
$adjust=604800 * floor($days / 5);
// how many days are left over
$remain=round($days % 5);
// check for negative
if ($hours<0) {
// check to see if we will land on a weekend, and make appropriate
adjustment
if (date("w",$date)<=$remain) {
$remain +=2;
}
// make the time adjustment, 8640 microseconds in a day, times the
remaining adjustment
$date -=($adjust +(86400 * $remain));
}
else {
// check to see if we will land on a weekend, and make appropriate
adjustment
if ((6-date("w",$date))<=$remain) {
$remain+=2;
}
// make the time adjustment, 8640 microseconds in a day, times the
remaining adjustment
$date +=($adjust +(86400 * $remain));

[PHP] Re: Calendar script - help
Your better off writing it from scratch than taking some pre-existing calendar/events
code. Break the problem up into two seperate pieces and solve for each - the creation
of a calendar view and the creation of a events view.
"I am a calendar and I know how to:"
Show a monthly view of myself
Move forward one month
Move backward one month
When a day is clicked I ask the events viewer to show an event
"I am a events viewer and I know how to:"
Show a event
Add a event
Edit a event
Delete a event
Create two classes, Calendar (calendar.php) and Events (events.php) that do the above.
The schema of the mySQL database is simple:
create table CalendarEvents
(
eventId int unsigned NOT NULL auto_increment primary key,
title varchar(64) NOT NULL,
eventDateStart DATE default '-00-00',
eventDateEnd DATE default '-00-00',
event text NOT NULL
);
Instead of entering in a date, why not click on the calendar's day to take you to a
form that will let you enter in the information. Here's some functions to helpin
generating the calendar, which is nothing more than a 6 row by 7 column table. Figure
out the start of the first day in the month via the FirstDayofMonth() function below.
Create blank cells up to that day, then generate the numbered days, along with
numbered day hyperlinks that when clicked, contain the month, day, year (e.g.
hyperlink for the day contains Events.php?m=11d=5y=2002). This will create your
context for the day. You will be able to $_GET the params from within Events.php. This
will allow you to insert/delete/edit the record for that day in the database.
function IsLeapYear($year)
{
return(date("L", mktime(0,0,0,1,1,$year)));
}
function FirstDayofMonth($month, $year)
{
// 0 - Sunday 6 - Saturday
return(date("w", mktime(0,0,0,$month,1,$year)));
}
function DaysInMonth($month, $year)
{
return(date("t", mktime(0,0,0,$month,1,$year)));
}
Good luck,

Dear All
I spent days and days on this little project but still cannot get it to work (new to
PHP as you might guess).
I have a script which is a combination of tutorial scripts and free code to display a
calendar with colour coded cells for the events on each day.
The only way to enter events is to enter them one at a time. What I want to do is to
be able to enter either a start date and end date or start date and the number of
days. This will then enter a new line in the mySQL database for each day. There would
only ever be one vent per day.
I have the following fields at present in the database and would probably need another
field (say number of days)
id int (auto_increment) - eventdate date ('-00-00') - title (varchar) - event
(blob)
Can anyone help me as I have searched them web and mail lists to no avail. Everything
that is available is excellent but does too much for what I need.
Summary:- a calendar that can colour code the background cells if there is an event
title in the mySQL database and to be able to enter the event for multiple days.
Any help would be very much appreciated.
Thanks for your time
Ray
