Question

PHP:Calendar

I've been trying to build a calendar using PHP.

Im using getdate and cal_days_in_month(CAL_GREGORIAN, $month, $year); to get the info I need to build a calendar.

What I'm trying to do  use the info from the getdate array to give me the months start date, and how may days in that month (got that info).

place the first date (1) in the row of a table that refelcts the day (sun=0) that starts at that position and will loop the cal_days_in_month, placing the other dates

in increasing order as it loops.

I'm having problem figuring out how to get PHP to find /get an html id tag (and then place that number into it).

If my logic is wrong, or someone has a better way, any help is appreciate

Your code sample looks inteesting but makes calls to three functions that are not included. firstDayMonth, weeksInMonth, and daysInMonth.

$dow = array('Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday');

function firstDayMonth($month, $year) // What day of the week is the first of the month
{
    $dayone = mktime(0,0,0, $month, 1, $year);
    $dayow = date('w', $dayone);
    return $dayow;
}

function daysInMonth($month, $year)
{
    $datetime = mktime(0, 0, 0, $month, 1, $year);
    $daysim = date('t', $datetime);
    return $daysim;
}

function weeksInMonth($month, $year) // how many weeks are in a month
{
    $date['fdom'] = firstDayMonth($month, $year);
