從用戶數據庫創建PHP數組

Question

我想創建這樣的數組$user["1"]，如何從數據庫創建這個數組？

$conn = new mysqli($servername, $username, $password, $dbname); 
if ($conn->connect_error) { } 

$sql = "SELECT * FROM Account"; 
$result = $conn->query($sql); 

if ($result->num_rows > 0) { 
    while($row = $result->fetch_assoc()) { 
     $id = $row["id"]; 
     $user[$id] = $row["username"]; 
    } 
} 
$conn->close(); 

Answer 1

請嘗試像這樣，插入前創建一個空數組$user。

$user = array(); 

if ($result->num_rows > 0) { 
    while($row = $result->fetch_assoc()) { 
     $id = $row["id"]; 
     $user[$i] = $row["username"]; 
    } 
} 

Answer 2

我固定它，我不得不添加的變化：

$user[$id] = $row["username"];

到：

$user["$id"] = $row["username"];
