如何使用mysql_fetch_array從MySQL獲取數據

Question

我想使用下面的代碼獲取MySQL數據，但它似乎有一些錯誤。任何人都可以請幫忙。謝謝！

<?php 
$link = mysqli_connect("localhost", "myusername", "mypassword", "mydb") or die("Error " . mysqli_error($link)); 
$query = "SELECT * FROM users WHERE id=2"; 
$res = mysqli_query($link, $query); 
$userRow = mysql_fetch_array($res); 

echo $userRow["user_firstname"]; 
?>
