simple calendar script

You need to create a simple calendar to be displayed in your website or web applicaiont?

It’s really simple to create a calendar in php, bellow is a small example on how easy it is.

The script gets the current date and builds a table calendar.

You can add day triggers, for example comming from a database, in this case it’s to display a birthdate.

Feel free to use and modify.

$date = time();

$day = date(‘d’, $date) ;
$year = date(‘Y’, $date) ;
$month = ’09’;

#calculate the first day
$first_day = mktime(0,0,0, $month  , 1, $year);

#retrieve the first day
$title = date(‘D’, $first_day);

#Get Month name
$month_name = date(‘F’, $first_day);

#Calculate how many days there are in the month
$days_in_month = date(‘t’,mktime(0,0,0,$month,$month,$year));

#Your birthday birthdate -> you can call any day or add an event::
$birthday = 25;

#Select  on which day of the week it starts the month
switch($title)
