来自Json的PHP唯一值

标签： php

我正在尝试从我的json响应中检索唯一的国家/地区代码列表。不幸的是，我没有运气，我认为我的代码已经偏离了轨道。

我的json回复如下：

我现在要做的是显示独特的“countryCode”＃39;价值（我知道的是＆＃39; GB＆＃39; IE＆＃39;。不幸的是，我的代码没有做太多。

这就是我所拥有的（对不起它现在已经过时了）：

<?php

$api_url = "http://localhost:8888/api/"; 


$jsondata = file_get_contents($api_url); 
$obj = json_decode($jsondata, true);





if (is_array($obj)){

    echo "<table>";
    echo "<tr>
            <th>Meeting</th>

         </tr>";
    foreach ($obj as $row){

        $meeting = $row["marketNam"];
        $race_id = $row["marketId"];
        $venue = $row["event"]["venue"];
        $date = $row["event"]["openDate"];
        $countryCode = $row["event"]["countryCode"];

        $dateFormatted = date('m/d/Y H:i:s', $date);


        $values = array_unique($countryCode, SORT_REGULAR);


        echo "<tr>";
            echo "<td><a href='#'>".$values."</a></td>";
            //echo "<td><a href='races.php?id=".$race_id."&venue=".$meeting."'>".$venue."</a></td>";
        echo "</tr>";
    }
    echo "</table>";
}

?>

1 个答案:

答案 0 :(得分：2)

在您的代码中，$countryCode将是单个值，而不是数组。我不确定你正在使用该表做什么，但这里有几种方法可以获得一个唯一的国家代码列表：

// iterate your data and add each item's country to a $countries array
foreach ($obj as $row) {
    $countries[] = $row['event']['countryCode'];
}
// use array_unique to remove duplicates
$countries = array_unique($countries);

或

// iterate your data and add each item's country to a $countries array
foreach ($obj as $row) {
    // using countryCode as the key will keep the array unique.
    $countries[$row['event']['countryCode']] = true;
}
//swap the keys to values
$countries = array_keys($countries);

使用其中一种方法意味着您必须在输出任何内容之前获取唯一列表，然后迭代结果列表以输出。
