如何循环json编码的数据？ [重复]

Question

我有一个功能

public function get_detail($subscriberid)
{
    $bigArray = array();

    $result = mysql_query("SELECT *  from prospect_requests WHERE subscriber_id = '$subscriberid'");
    //$user_data = mysql_fetch_array($result);
    $no_rows = mysql_num_rows($result);

    while( $row = mysql_fetch_assoc( $result))
    {
        $bigArray[] = $row;
    }
    return json_encode($bigArray);
}

我通过使用 html 中的用户类对象来调用此函数，它以表单数组的形式返回数据。

我正在尝试在我的 HTML 表中填充这些值，我是否使用以下方法。

<table>
    <?php
    $ary = json_decode($user->get_detail($uid));
        echo "<tr>"         
            foreach($ary as $key=>$value) {
                echo "<td>";
                    print  $key['$value'];
                echo "</td>";
            }
        echo "</tr>";
    ?>

上面的

foreach()

不是为我打印的，但是当我打印

print_r($ary);

时，我得到了想要的数组。

请告诉我为什么值没有填充到表中。

更新 print_r($ary) 的输出

Answer 1

试试这个：

json_decode($user->get_detail($uid), true);

参考：http://php.net/manual/en/function.json-decode.php

当为 TRUE 时，返回的对象将被转换为关联数组。

Answer 2

json_decode - 获取 JSON 编码字符串并将其转换为 PHP 变量。

mixed json_decode ( string $json [, bool $assoc = false [, int $depth = 512 [, int $options = 0 ]]] )

assoc - 当

TRUE

时，返回的对象将被转换为关联数组。

json_decode($user->get_detail($uid), TRUE);

如果您要以数组形式访问这些值。
