來自Json的PHP唯一值

我想從我的json響應中檢索唯一國家/地區代碼的列表。不幸的是，我沒有任何運氣，我認爲我的代碼已經走上正軌。來自Json的PHP唯一值

我的JSON響應的樣子：

和我所試圖做的是現在可以顯示獨特的「COUNTRYCODE」值（我知道是「國標」和「IE」不幸的是我，我的代碼是沒有做多少

這裏是我有什麼（對不起它不見了那種草率現在）：

<?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>"; 
} 

?>

在你的代碼中，'$ countryCode'將是一個單一的值，而不是一個數組。 –

在你的代碼，$countryCode將是一個值，而不是AR射線。我不知道你是用表格做什麼，但這裏有一對夫婦的方式來獲得的國家代碼唯一列表：

// 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);

使用這些方法中的一種意味着在輸出任何東西之前你必須得到唯一的列表，然後遍歷結果列表輸出。
