PHP通过多维数组循环

Question

嗨，我在PHP中有这个多维数组：

$team_arrays = array (
                        "lakers" => array (
                                        24 => "Bryant",
                                        6  => "Price",
                                        17 => "Lin"
                        ),

                        "knicks" => array (
                                        7 => "Anthony",
                                       22 => "Shumpert",
                                       12 => "Jackson"
                        ),

                        "thunder" => array (
                                       35 => "Durant",
                                       0  => "Westbrook",
                                       13 => "Miller"
                        )
                    );

我想要显示如下内容：

球队名称：湖人

1. Bryant = 24
2. 价格= 6
3. 林= 17

球队名称：尼克斯

1. Anthony = 7
2. Shumpert = 22
3. 杰克逊= 12

...

这是我尝试但似乎不起作用的代码：

foreach ($team_arrays as $names => $team) {
                        echo "<h2>Team Name: " . $names . "</h2>";
                        echo "<ol>";
                            foreach ($team_arrays as $jersey => $names) {
                                echo "<li>" . $names . " = " . $jersey . "</li>";
                            }
                        echo "</ol>";
                    }

它会产生这种错误

Notice: Array to string conversion in

有人会尝试寻求帮助。请。

我从其他问题中找到了这个solution，但似乎我无法与之相关。

Answer 1

您的代码中只有一个小问题

foreach ($team_arrays as $jersey => $names) {
         ^ // again looping over the same outer array?

内部循环错误，你应该遍历$team而不是$team_arrays，因为你的外部循环使用$team变量来接收每个团队。

foreach ($team as $jersey => $names) {

其余的代码和逻辑已经很好了。

Answer 2

您需要更改此行;

 foreach ($team_arrays as $jersey => $names) {

为：

   foreach ($team as $jersey => $names) {

Answer 3

更改为foreach ($team as $jersey => $names)

试试这个：     

$team_arrays = array (
                        "lakers" => array (
                                        24 => "Bryant",
                                        6  => "Price",
                                        17 => "Lin"
                        ),

                        "knicks" => array (
                                        7 => "Anthony",
                                       22 => "Shumpert",
                                       12 => "Jackson"
                        ),

                        "thunder" => array (
                                       35 => "Durant",
                                       0  => "Westbrook",
                                       13 => "Miller"
                        )
                    );

 foreach ($team_arrays as $names => $team) {
                        echo "<h2>Team Name: " . $names . "</h2>";
                        echo "<ol>";
                            foreach ($team as $jersey => $names) {
                                echo "<li>" . $names . " = " . $jersey . "</li> \n";
                            }
                        echo "</ol>";
                    }                   
 ?>
