使用mysql/php對前三名排序

Question

我想從我的數據庫中獲得三個具有最高值的實體，對它們進行排序並將它們放在每個div中，就像前三名的記分板一樣。我也將能夠分隔字段（ID，名稱，說明等）和檢索那些通過使用例如：

<?php echo $sql['id']; ?> 

我已經知道的代碼來獲取信息，並對其進行排序：

$sql = ("SELECT * FROM table ORDER BY tablefield DESC LIMIT 3"); 

但我不知道如何將三個實體放入他們的每一個div的和獨立實體的領域，如名稱，說明等

如果你正在使用MySQL（PDO），我強烈建議，那麼它的完成如下：

$sql = "SELECT * FROM table ORDER BY tablefield DESC LIMIT 3"; 
$stmt = $conn->prepare($sql); 
$stmt->execute(); 

/*here you get a multidimentional array with the information you wanted*/ 
$rows = $stmt->fetchAll(PDO::FETCH_ASSOC); 


//this would be one method of extracting the information 
//If you want to place them in specific divs as your 
//question suggests, then you could just use the array 
//inside the divs instead than echoing them out in 
//this foreach loop 

foreach ($rows as $row) 
{ 
    foreach ($row as $key => $value) 
    { 
    echo $key.": ".$value."<br>"; 
    } 
    echo "<br>"; 
} 

/*alternatively you could just use: 

print_r($rows); 

if you just want to have a quick look at the 
composition of the array*/
