Question

我有一个这样的数组：

$games_array = array(

  "game-one-id" => array(
      array("name" => "Game One"),
      array("url" => "game-one-url"),
      array("asd" => "asdfg")
  ),

  "game-two-id" => array(
      array("name" => "Game Two"),
      array("url" => "game-two-url"),
      array("asd" => "asdfg")
  )

);

我希望列出$games_array中的所有游戏并打印每个游戏的一些属性，例如其网址。

这就是我提出的，但没有打印出来：

foreach ($games_array as $game_id => $game_data) {
  echo '  
    <table><tr>
    <td><a href="http://www.example.com/game/' . $game_data["url"] . '/">' . $game_data["name"] . '</a></td>
    </tr></table>
  ';
}

有人可以帮助我吗

Answer 1

该循环与这样的数组相关

$games_array = array(

"game-one-id" => array(
    "name" => "Game One",
    "url" => "game-one-url",
    "asd" => "asdfg"
),

"game-two-id" => array(
    "name" => "Game Two",
    "show_compatibility" => "game-two-url",
    "asd" => "asdfg"
)

);

尝试！：）

Answer 2

使用您正在使用的$game_array，您应该使用：

foreach ($games_array as $game_id => $game_data) {
  echo '  
    <table><tr>
    <td><a href="http://www.example.com/game/' . $game_data[1]["url"] . '/">' . $game_data[0]["name"] . '</a></td>
    </tr></table>
  ';
}

变量$game_array应为：

$games_array = array(

  "game-one-id" => array(
      "name" => "Game One",
      "url" => "game-one-url",
      "asd" => "asdfg"
  ),

  "game-two-id" => array(
      "name" => "Game Two",
      "show_compatibility" => "game-two-url",
      "asd" => "asdfg"
  )

);

如果您想使用：

foreach ($games_array as $game_id => $game_data) {
  echo '  
    <table><tr>
    <td><a href="http://www.example.com/game/' . $game_data["url"] . '/">' . $game_data["name"] . '</a></td>
    </tr></table>
  ';
}

Answer 3

尝试此操作而不更改数组格式。

<?php
    $games_array = array(

      "game-one-id" => array(
          array("name" => "Game One"),
          array("url" => "game-one-url"),
          array("asd" => "asdfg")
      ),

      "game-two-id" => array(
          array("name" => "Game Two"),
          array("url" => "game-two-url"),
          array("asd" => "asdfg")
      )

    );
    foreach ($games_array as $game_id => $game_data) {
        //var_dump($game_data);
      echo '  
        <table><tr>
        <td><a href="http://www.example.com/game/' . $game_data[1]["url"] . '/">' . $game_data[0]["name"] . '</a></td>
        </tr></table>
      ';
    }


    ?>

将数组格式更改为

$games_array = array(

"game-one-id" => array(
    "name" => "Game One",
    "url" => "game-one-url",
    "asd" => "asdfg"
),

"game-two-id" => array(
    "name" => "Game Two",
    "show_compatibility" => "game-two-url",
    "asd" => "asdfg"
)

);

Answer 4

应该是这样的：

foreach ($games_array as $game_id => $game_data) {
   echo '  
    <table><tr>
    <td><a href="http://www.example.com/game/' . $game_data["url"] . '/">' . $game_data[0]["name"] . '</a></td>
    </tr></table>
  ';
}

您指定为子游戏-id-id的每个数组都没有键。默认情况下，它将从0开始为一个键，并且每次上升1。我想你可能宁愿这样做：

$games_array = array(

"game-one-id" => array("name" => "Game One","url" => "game-one-url","asd" => "asdfg")

）;

foreach ($games_array as $game_id => $game_data) {
   echo '  
    <table><tr>
    <td><a href="http://www.example.com/game/' . $game_data["url"] . '/">' . $game_data["name"] . ' - ' . $game_data["url"] . '</a></td>
    </tr></table>
  ';
}

按键打印多维数组
