将SQL结果保存为php函数作为数组

Question

所以我基本上试图通过php函数从SQL获取quote_author和quote_text结果，然后以风格化的html显示它。当我调用函数时我想获得2个变量$ quote_text和$ quote_author，所以我可以将它们放在html中的两个separe div中，因为它们的风格化程度不同。

这是我的代码

function get_quotes(){

$connection = mysqli_connect("localhost","xxx","xxx","xxx");
$sql = "SELECT quote_text, quote_author FROM quotes ORDER BY rand() LIMIT 1";
$result = mysqli_query($connection,$sql);
while($row = mysqli_fetch_assoc($result)) {
       //how can I get the two results $row['quote_text'] and $row['quote_author'] 
       //out of the function
   }
}

get_quotes();
echo $row['quote_text'];
echo $row['quote_author'];

提前致谢！

Answer 1

您应该使用return语句从函数返回结果。您也不需要while循环，因为查询只返回一行。

$row = mysqli_fetch_assoc();
return $row;

然后来电者做：

$row = get_quotes();
if ($row) {
    echo $row['quote_text'];
    echo $row['quote_author'];
}

Answer 2

您应该执行以下操作：

function get_quotes(){
    $connection = mysqli_connect("localhost","xxx","xxx","xxx");
    $sql = "SELECT quote_text, quote_author FROM quotes ORDER BY rand() LIMIT 1";
    $result = mysqli_query($connection,$sql);
    return mysqli_fetch_assoc($result);
}

$row = get_quotes();
echo $row['quote_text'];
echo $row['quote_author'];
