如何获取“球员”数据，我想在我的 PHP Wordpress 网站上使用“最高得分手站立小部件”。

{
    "?xml":{
        "@version":"1.0",
        "@encoding":"utf-8"
    },
    "topscorers":{
        "@sport":"soccer",
        "tournament":{
            "@name":"Premier League",
            "@stage_id":"12041081",
            "@gid":"1204",

回答

https://www.php.net/manual/en/function.json-decode.php

为此，您必须首先将 json 字符串解码为 php 对象。然后，您必须深入了解您想要的正确数据。您可以使用 -> 运算符来执行此操作，如下所示：

$players = json_decode($raw_string)->{'topscorers'}->{'tournament'}->{'player'};

请注意，如果您打算重用数据，则应保存解码后的 json 字符串的结果。不要多次解码。

拥有玩家之后，您可以遍历数据并使用它做您想做的事情。这是您的数据的一个最小示例，因此您可以看到它们一起工作。

示例

数据集

<?php

$raw_string = '
{
    "?xml":{
        "@version":"1.0",
        "@encoding":"utf-8"
    },
    "topscorers":{
        "@sport":"soccer",
        "tournament":{
            "@name":"Premier League",
            "@stage_id":"12041081",
            "@gid":"1204",
            "@is_current":"True",
            "@id":"1204",
            "player":[
                {
                    "@pos":"1",
                    "@name":"Mohamed Salah",
                    "@team":"Liverpool",
                    "@team_id":"9249",
                    "@goals":"15",
                    "@penalty_goals":"2",
                    "@id":"138653"
                },
                {
                    "@pos":"2",
                    "@name":"Diogo Jota",
                    "@team":"Liverpool",
                    "@team_id":"9249",
                    "@goals":"10",
                    "@penalty_goals":"0",
                    "@id":"374031"
                },
                {
                    "@pos":"3",
                    "@name":"J. Vardy",
                    "@team":"Leicester City",
                    "@team_id":"9240",
                    "@goals":"9",
                    "@penalty_goals":"0",
                    "@id":"159732"
                }
            ]
        }
    }
}';
?>

处理

<?php
$php_object = json_decode($raw_string);
$players = $php_object->{'topscorers'}->{'tournament'}->{'player'};

$html = '';
$html .= '<table>';
$html .= '<tr>';
$html .= '<td>Pos</td>';
$html .= '<td>Player</td>';
$html .= '<td>Team</td>';
$html .= '<td>Goals</td>';
$html .= '</tr>';


foreach ($players as $p) {
  $html .= '<tr>';
  $html .= '<td>' . $p->{'@pos'}   . '</td>';
  $html .= '<td>' . $p->{'@name'}  . '</td>';
  $html .= '<td>' . $p->{'@team'}  . '</td>';
  $html .= '<td>' . $p->{'@goals'} . '</td>';
  $html .= '</tr>';
}

$html .= '</table>';

echo($html);

?>

输出

<table><tr><td>Pos</td><td>Player</td><td>Team</td><td>Goals</td></tr><tr><td>1</td><td>Mohamed Salah</td><td>Liverpool</td><td>15</td></tr><tr><td>2</td><td>Diogo Jota</td><td>Liverpool</td><td>10</td></tr><tr><td>3</td><td>J. Vardy</td><td>Leicester City</td><td>9</td></tr></table>

Pos	Player	Team	Goals
1	Mohamed Salah	Liverpool	15
2	Diogo Jota	Liverpool	10
3	J. Vardy	Leicester City	9
