Generating a partially filled table - php

Question

I'm currently trying to generate a table with every weekday of a month filled with data from a database.
That all works fine, but I want to show the empty dates as well. So:
for (/*each weekday of the month*/) {
if ($row['date'] == /*that day of the month*/)
echo /*the data for that day*/;
else
echo /*empty row*/;
}
That's how I suppose it would look like, but I have no clue on how to do this in a decent fashion.
I hope someone can give me a hand in this.
Final code:
$data = array();
$numofdays = date(t, $monthstamp);
while ($row = $res->fetch_assoc()) {
$monthstamp = mktime(0, 0, 0, $month, 1, $year);
for ($i=1; $i<$numofdays; $i++) {
$monthstamp = mktime(0, 0, 0, $month, $i, $year);
if (strtotime($row['datum']) == $monthstamp) {
echo 'Entry added for day '.$i.'<br>';
$data[] = $i;
}
}
}
for ($i=1; $i<$numofdays; $i++) {
if (in_array($i, $data))
echo 'date ' . $i . ' is full<br>';
else
echo 'date ' . $i . ' is empty<br>';
}

Answer 1

Exactly what you suggested works. Something like this (pseudocode)
// create a date
$year = 2013;
for$month=1; $month<13;$month++;)
{
// create date for each day of each month, or just use an array with number of days in each month, which is easier imho
$MonthStamp = mktime(1, 1, 1, $month, 1, $year);
// get number of days
$NumOfDays = date(t, $MonthStamp);
for($i=1; $i=<$NumOfDays; $i++)
{
if ($row['date'] == // Not sure how your date is formatted. create same date format
echo /*the data for that day*/;
else
echo /*empty row*/;
}
}

Answer 2

You will need to format into table / divs and change format of $row to match your DB row but this should work.
// You would get your dates from DB here
$row = array
(
"01-01-2013" => "New Years Day",
"31-01-2013" => "Holiday",
);
$year = 2013;
for ($month = 1; $month <= 12; $month++)
{
$monthStamp = mktime(1, 1, 1, $month, 1, $year);
$daysInMonth = date('t', $monthStamp);
for($i = 1; $i <= $daysInMonth; $i++)
{
$date = date("d-m-Y", mktime(1,1,1, $month, $i, $year) );
echo $date;
// Check to see if any events in $row and echo result is true
if ( isset($row[$date]) )
{
echo " : " . $row[$date];
}
echo "<br>";
}
}
