PHP date_create_from_format無法轉換爲字符串

Question

我轉換做日期一些輸入變量與date_create_from_format，但符合$diff2給我錯誤'不能轉換爲字符串'我不知道爲什麼...代碼看起來像

/* 
      array['id'] = el.attr('data-id'); 
    array['name'] = el.attr('data-name'); 
    array['place'] = el.attr('data-place'); 
    array['color'] = el.attr('data-color'); 
    array['day'] = $(this).attr('data-day'); 
    array['month'] = $(this).attr('data-month'); 
    array['year'] = $(this).attr('data-year'); 
    array['interval'] = el.attr('data-interval'); 
    array['notification'] = el.attr('data-notification'); 
    array['hourFrom'] = formatTime(mousingDayH); 
    array['hourFrom'] = formatTime(mousingDayM); 
    arra['hour'] = formatTime(el.attr('data-hour')); 
    array['minutes'] = formatTime(el.attr('data-minutes')); 
    array['hourTo'] = formatTime(el.attr('data-hourTo')); 
    array['minutesTo'] = formatTime(el.attr('data-minutesTo'));   


     */ 


function updateDayCalendarEventInTimelineByDrag($array){ 
     global $db; 

     $array->hour = intval($array->hour); 
     $array->minutes = intval($array->minutes); 
     $array->hourFrom = intval($array->hourFrom); 
     $array->minutesFrom = intval($array->minutesFrom); 
     $array->hourTo = intval($array->hourTo); 
     $array->minutesTo = intval($array->minutesTo); 

     ($array->hour <= 9 ? $array->hour = '0'.$array->hour : $array->hour = $array->hour); 
     ($array->minutes <= 9 ? $array->minutes = '0'.$array->minutes : $array->minutes = $array->minutes); 
     ($array->hourFrom <= 9 ? $array->hourFrom = '0'.$array->hourFrom : $array->hourFrom = $array->hourFrom); 
     ($array->minutesFrom <= 9 ? $array->minutesFrom = '0'.$array->minutesFrom : $array->minutesFrom = $array->minutesFrom); 
     ($array->hourTo <= 9 ? $array->hourTo = "0".$array->hourTo : $array->hourTo = $array->hourTo); 
     ($array->minutesTo <= 9 ? $array->minutesTo = '0'.$array->minutesTo : $array->minutesTo = $array->minutesTo);  
     $diff2 = date_create_from_format("G:i/j.n.Y", $array->hourTo.":".$array->minutesTo."/".$array->day.".".$array->month.".".$array-year); 
    echo $diff2;` 
}

還有在最後一行一個錯字：$array-year應該$array->year。
