PHP通過多維數組循環

Question

嗨我在PHP中有這個多維數組：

$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"
                        )
                    );

我想要顯示如下內容：

球隊名稱：湖人隊

1. 布萊恩特= 24
2. 價格= 6
3. 林= 17

球隊名稱：尼克斯隊

1. 安東尼= 7
2. 香波特= 22
3. 傑克遜= 12

...

這是我嘗試但似乎不起作用的代碼：

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>";
                    }

它會產生這種錯誤

Notice: Array to string conversion in

有人會試圖尋求幫助。 請。

我從其他問題中找到了這個解決方案 ，但似乎我無法與之相關。

Answer 1

您的代碼中只有一個小問題

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

那個內循環是錯誤的，你應該遍歷$team而不是$team_arrays因為你的外循環使用$team變量來獲取每個團隊。

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

其余的代碼和邏輯已經很好了。

Answer 2

您需要更改此行;

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

至：

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

Answer 3

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

嘗試這個 ：

$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>";
                    }                   
 ?>
