PDO讓追隨者

Question

數這裏是我的代碼

$sql1 = "SELECT * FROM user_follow WHERE user = :user"; 

     $stmt1 = $conexao_pdo->prepare($sql1); 
     //where clause         
     $stmt1->bindParam(':user', $username); 
     $stmt1->execute(); 
while ($row1 = $stmt1->fetch(PDO::FETCH_ASSOC)) 
{ 
echo '</br>Followers: </br>'.$row1['followers'].'</br>'; 


} 

它表明追隨者的名字，但我想在PDO一個實施也顯示出的$row1['followers']

Answer 1

數字量如果只需要計數你可以使用rowCount()功能：

$stmt1->execute(); 
$count = $stmt1->rowCount(); 
echo '</br>Followers: </br>'.$count.'</br>'; 

所以它只是回聲$算
