私は、xmlファイルを解析して配列にする関数を持っています。

<?php 

$xml = simplexml_load_file('hascompany.xml'); 
$json = json_encode($xml); 
$shops = json_decode($json, true); 

echo "<pre>"; 
print_r($shops); 
echo "</br></br>"; 
print_r(count($shops['shops']['basead']['shop'])); 
echo "</br>"; 
print_r(count($shops['shops']['basead'])); 
echo "</br></br>"; 

logCompanyData($shops); 

function logCompanyData($shops) 
{ 
    foreach ($shops['shops']['basead']['shop'] as $company) 
    { 
     $companyId = $company['id']; 
     $entryName = $company['entryname']; 
     $priority = $company['priority']; 
     $searchNum = $company['searchnum']; 

     echo 'company_id = ' . $companyId . '<br />'; 
     echo 'company_name = ' . $entryName . '<br />'; 
     echo 'company_prio = ' . $priority . '<br />'; 
     echo 'company_searchno = ' . $searchNum . '<br /><br />'; 
    } 
} 

?>

<shop>のデータが2つある場合、スクリプトは両方の詳細を返します。しかし、私が1を取り除くまで、<shop>スクリプトはエラーを返します。不正な文字列オフセット。おそらく配列が正しくないためです。

私は結果を見ることができるようにエコーを介して配列を表示しようとしましたが、削除することもできます。

これは、xmlファイルに2がある場合はprint_r（$ shops）の結果です。<shop>;

完全なエラーメッセージを表示して、それが指しているコード行を暗示します（ファイル名と行番号にはアクセスできません） – Calimero

@AlivetoDie申し訳ありませんが、$ limitは余計なパラメータです。無駄です。内容を編集しました。私も完全なエラーを追加しました。 –

@Calimero結果を追加しました。もう一度確認してください –

あなたは$shops['shops']['basead']['shop']は多次元配列であるか、ないことを最初にチェックする必要がありますか？はい、その後印刷するforeach()を使用してそれ以外の場合は、直接以下のようなechoを使用する場合： -

function logCompanyData($shops){ 

    if(count($shops['shops']['basead']['shop']) == count($shops['shops']['basead']['shop'], COUNT_RECURSIVE)){ 
     echo 'company_id = ' . $shops['shops']['basead']['shop']['id'] . '<br />'; 
     echo 'company_name = ' . $shops['shops']['basead']['shop']['entryname'] . '<br />'; 
     echo 'company_prio = ' . $shops['shops']['basead']['shop']['priority'] . '<br />'; 
     echo 'company_searchno = ' . $shops['shops']['basead']['shop']['searchnum'] . '<br /><br />'; 
}else{ 

     foreach ($shops['shops']['basead']['shop'] as $company) 
     { 
      echo 'company_id = ' . $company['id'] . '<br />'; 
      echo 'company_name = ' . $company['entryname'] . '<br />';

      echo 'company_searchno = ' . $company['searchnum'] . '<br /><br />';
