從MySQL獲得錶行PHP數組

Question

$sql = "SELECT active FROM table_name"; 
$result = $conn->query($sql); 

DB：

|active| 
1 
1 
0 
1 

我有臺這樣並需要獲得行到一個數組。 是否有可能獲得簡單數組這樣？：

$array = (1,1,0,1); 

感謝

Answer 1

$sql = "SELECT active FROM table_name"; 

$result = $conn->query($sql); 

while($row = $result->fetch_assoc()) { 
     $arr[]= $row['active']; 
    } 

print_r($arr); 

Answer 2

$sql = "SELECT active FROM table_name"; 
$result = $conn->query($sql); 

$arr=array(); 

foreach($result as $res) 
{ 
    array_push($arr,$res->active); 
} 

var_dump($arr);
