Question

我有一个如下所示的数组：

阵列

Array
(
    [Team 1] => Array
        (
            [wins] => 60
        )

    [Team 2] => Array
        (
            [wins] => 12
        )

    [Team 3] => Array
        (
            [wins] => 79
        )

    [Team 4] => Array
        (
            [wins] => 36
        )

    [Team 5] => Array
        (
            [wins] => 29
        )

)

然后我跨越了使用php foreach

显示结果

HTML

<span><?php echo ['Team 1']['wins'] ?></span>
<span><?php echo ['Team 2']['wins'] ?></span>
<span><?php echo ['Team 3']['wins'] ?></span>
<span><?php echo ['Team 4']['wins'] ?></span>
<span><?php echo ['Team 5']['wins'] ?></span>

我希望在每个团队旁边显示一些文字，给他们排名1-5，基于他们的＆＃34;胜利＆＃34;值。我希望输出看起来像这样。有没有办法计算＆＃34;胜利＆＃34;并使用wins值给出1到5的排名？

预期结果

<span><?php echo "#2" ['Team 1']['wins'] ?></span>
<span><?php echo "#5" ['Team 2']['wins'] ?></span>
<span><?php echo "#1" ['Team 3']['wins'] ?></span>
<span><?php echo "#3" ['Team 4']['wins'] ?></span>
<span><?php echo "#4" ['Team 5']['wins'] ?></span>

您可以使用array multi_sort

<强>阵列

<?php 
$inventory = 
Array
(
    'Team 1'=> Array
        (
            'wins' => 60
        ),

    'Team 2' => Array
        (
            'wins' => 12
        ),

    'Team 3' => Array
        (
            'wins' => 79
        ),

    'Team 4' => Array
        (
            'wins' => 36
        ),

    'Team 5' => Array
        (
            'wins' => 29
        ),

);
?>

<强> PHP

<?php 
$inventory2 = $inventory;
$kol = array();
$a = 1;

array_multisort($inventory, SORT_DESC);
foreach ($inventory as $key=>$value)
{
    $kol[$key] = $value;
    $kol[$key]['rank'] = $a++;
}

$ar = array_merge($inventory2,$kol);

?>

<强> HTML

<!DOCTYPE html>
<html>
<head>
    <title></title>
</head>
<body>
<?php foreach ($ar as $key => $value) { ?>
<span><?php echo $key ?></span><br> WINS : <?php echo $value['wins'] ?></span>
</br>Rank : <?php echo $value['rank'] ?></span>
</br></br>
<?php } ?>
</body>
</html>

试试这段代码，它应该从最大到最小排序。

获取数组值并分配排名
