Php and MySQL calendar modification - php

Question

This code creates a nice calendar (original code), but I'm trying to make some modifications on it.
The first lines are ok, no need to pay attention to that, but here it is:
$calendar = '<table cellpadding="0" cellspacing="0" class="calendar">';
$headings = array('Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday');
$calendar.= '<tr class="calendar-row"><td class="calendar-day-head">'.implode('</td><td class="calendar-day-head">',$headings).'</td></tr>';
$running_day = date('w',mktime(0,0,0,$month,1,$year));
$days_in_month = date('t',mktime(0,0,0,$month,1,$year));
$days_in_this_week = 1;
$day_counter = 0;
$dates_array = array();
$calendar.= '<tr class="calendar-row">';
for($x = 0; $x < $running_day; $x++):
$calendar.= '<td class="calendar-day-np"> </td>';
$days_in_this_week++;
endfor;
Here is where I stucked. From now on, the calendar access the database and print my dates based on the events I have recorded. For the dates that the query has found any event, than the code prints a link in it. See the code:
$db = new PDO('mysql:host=localhost;dbname=calendar','root','');
$stmt = $db->prepare('SELECT time, title FROM events');
$stmt->execute();
$rawTimeStamps = $stmt->fetchAll(PDO::FETCH_ASSOC);
$cleanDateArray = array();
foreach ($rawTimeStamps as $t) {
$rawDate = $t['time'];
$rawDate = getdate($rawDate);
$cleanDate = mktime(0,0,0,$rawDate['mon'],$rawDate['mday'],$rawDate['year']);
$cleanDataArray[] = $cleanDate;
}
for($list_day = 1; $list_day <= $days_in_month; $list_day++):
$calendar.= '<td class="calendar-day">';
$timestamp = mktime(0,0,0,$month,$list_day,$year);
if (in_array($timestamp, $cleanDataArray)) {
$calendar.= '<div class="day-number day-number-event">'.$list_day.'</div>';
} else {
$calendar.= '<div class="day-number day-number-noevent">'.$list_day.'</div></div><div id="calendar-events"></div>';
}
$calendar.= '</td>';
if($running_day == 6):
$calendar.= '</tr>';
if(($day_counter+1) != $days_in_month):
$calendar.= '<tr class="calendar-row">';
endif;
$running_day = -1;
$days_in_this_week = 0;
endif;
$days_in_this_week++; $running_day++; $day_counter++;
endfor;
And than, the code finishes the calendar.
if($days_in_this_week < 8):
for($x = 1; $x <= (8 - $days_in_this_week); $x++):
$calendar.= '<td class="calendar-day-np"> </td>';
endfor;
endif;
$calendar.= '</tr>';
$calendar.= '</table>';
return $calendar;
What I need is to print other infos from the database related to the date that has an event. In other words, all I want is to print the events title (that are also recorded in a column of the events table) right below the event data. Something like:
$calendar.= '<div class="day-number day-number-event"><a id="'.$timestamp.'" href="#">'.$list_day.'</a></div><p>'.$title.'</p>';}

After some tests and studies, this is the solution:
function draw_calendar($month,$year){
$calendar = '<table cellpadding="0" cellspacing="0" class="calendar">';
$headings = array('Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday');
$calendar.= '<tr class="calendar-row"><td class="calendar-day-head">'.implode('</td><td class="calendar-day-head">',$headings).'</td></tr>';
/* days and weeks vars now ... */
$running_day = date('w',mktime(0,0,0,$month,1,$year));
$days_in_month = date('t',mktime(0,0,0,$month,1,$year));
$days_in_this_week = 1;
$day_counter = 0;
$dates_array = array();
/* row for week one */
$calendar.= '<tr class="calendar-row">';
/* print "blank" days until the first of the current week */
for($x = 0; $x < $running_day; $x++):
$calendar.= '<td class="calendar-day-np"> </td>';
$days_in_this_week++;
endfor;
$db = new PDO('mysql:host=localhost;dbname=calendar','root','');
$stmt = $db->prepare('SELECT time, title FROM events');
$stmt->execute();
$rawTimeStamps = $stmt->fetchAll(PDO::FETCH_ASSOC);
$cleanDateArray = array();
foreach ($rawTimeStamps as $t) {
$rawDate = $t['time'];
$rawDate = getdate($rawDate);
$cleanDate = mktime(0,0,0,$rawDate['mon'],$rawDate['mday'],$rawDate['year']);
$cleanDataArray[] = $cleanDate;
}
/* keep going with days.... */
for($list_day = 1; $list_day <= $days_in_month; $list_day++):
$calendar.= '<td class="calendar-day">';
$timestamp = mktime(0,0,0,$month,$list_day,$year);
if (in_array($timestamp, $cleanDataArray)) {
/* embromation */
$date = getdate($timestamp);
$time_start = mktime(0,0,0,$date['mon'],$date['mday'],$date['year']);
$time_end = mktime(23,59,59,$date['mon'],$date['mday'],$date['year']);
$stmt = $db->prepare('SELECT title FROM events WHERE time BETWEEN ? AND ?');
$stmt->bindParam(1,$time_start,PDO::PARAM_INT);
$stmt->bindParam(2,$time_end,PDO::PARAM_INT);
$stmt->execute();
$events = $stmt->fetch(PDO::FETCH_ASSOC);
$calendar.= '<div class="day-number day-number-event">'.$list_day.'</div><p>'.$events["title"].'</p>';
} else {
$calendar.= '<div class="day-number day-number-noevent">'.$list_day.'</div></div><div id="calendar-events"></div>';
}
$calendar.= '</td>';
if($running_day == 6):
$calendar.= '</tr>';
if(($day_counter+1) != $days_in_month):
$calendar.= '<tr class="calendar-row">';
endif;
$running_day = -1;
$days_in_this_week = 0;
endif;
$days_in_this_week++; $running_day++; $day_counter++;
endfor;
/* finish the rest of the days in the week */
if($days_in_this_week < 8):
for($x = 1; $x <= (8 - $days_in_this_week); $x++):
$calendar.= '<td class="calendar-day-np"> </td>';
endfor;
endif;
/* final row */
$calendar.= '</tr>';
/* end the table */
$calendar.= '</table>';
/* all done, return result */
return $calendar;
}
