PHP mysqli_fetch_assoc() 函数

从结果集中取得一行作为关联数组：

<?php
// 假定数据库用户名：root，密码：123456，数据库：RUNOOB
$con=mysqli_connect("localhost","root","123456","RUNOOB");
if (mysqli_connect_errno($con))
{
    echo "连接 MySQL 失败: " . mysqli_connect_error();
} 

$sql="SELECT name,url FROM websites ORDER BY alexa";
$result=mysqli_query($con,$sql);

// 关联数组
$row=mysqli_fetch_assoc($result);
printf ("%s (%s)\n",$row["name"],$row["url"]);

// 释放结果集
mysqli_free_result($result);

mysqli_close($con);
?>
