Php和MySQL日曆修改

Question

此代碼創建了一個不錯的日曆（original code），但我試圖對其進行一些修改。 第一行是行，沒必要注意這一點，但在這裏它是：

$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; 

這裏就是我stucked。從現在起，日曆訪問數據庫並基於我記錄的事件打印我的日期。對於查詢發現任何事件的日期，代碼將在其中打印鏈接。看代碼：

$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)) { 
     $calendar.= '<div class="day-number day-number-event"><a href="#">'.$list_day.'</a></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; 

而且，代碼完成日曆。

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; 

我需要的是從數據庫中打印與事件日期相關的其他信息。換句話說，我想要的只是在事件數據的正下方打印事件標題（也記錄在事件表的一列中）。喜歡的東西：

$calendar.= '<div class="day-number day-number-event"><a id="'.$timestamp.'" href="#">'.$list_day.'</a></div><p>'.$title.'</p>';}

一些測試和研究後，這是解決方案：

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); 

     $calendar.= '<div class="day-number day-number-event"><a href="#">'.$list_day.'</a></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;
