从数组中提取特定数据

                )

我只想从每个数组中提取ID名称totalsessionsplayed，totalsessionslost和totalsessionswon，并将其显示在表格中。

我还没有办法让它发挥作用。

Answer 1

我认为这是你正在寻找的东西：

echo '<table>';
foreach($arr['champions'] as $entry) {
    echo '<tr>';
    echo '<td>' . $entry['id'] . '</td>';
    echo '<td>' . $entry['name'] . '</td>';
    echo '<td>' . $entry['stats']['totalSessionsPlayed'] . '</td>';
    echo '<td>' . $entry['stats']['totalSessionsLost'] . '</td>';
    echo '<td>' . $entry['stats']['totalSessionsWon'] . '</td>';
    echo '</tr>';
}
echo '</table>';

Answer 2

您可以从champions子数组开始访问您的值，然后使用foreach()迭代它：

<?php 
$your_array = ...

foreach($your_array['champions'] as $row){

    //get the values, dont really need to reassign but you get the idea
    $id = $row['id'];
    $name = $row['name'];
    $played = $row['stats']['totalSessionsPlayed'];
    $lost = $row['stats']['totalSessionsLost'];
    $won = $row['stats']['totalSessionsWon'];

    //do something with them values on each iteration
}
?>

Answer 3

你可以在php中做一个foreach循环来获取你需要的数据。我使用$ array作为您持有数组的变量的名称：

foreach($array['champions'] as $thischamp) {
$id = $thischamp['id'];
$name = $thischamp['name'];
$totalsessions = $thischamp['stats']['totalsessionsplayed'];
$totallost = $thischamp['stats']['totalsessionslost'];
$totalwon = $thischamp['stats']['totalsessionswon'];
// now write your html
}
