使用foreach在数组中获取数据

所以我有这个XML文件;使用foreach在数组中获取数据

我有一个函数，可以将xml文件解析成数组;

<?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 />'; 
    } 
} 

?>

当有两个<shop>数据时，该脚本返回两者的详细信息。但直到我删除1 <shop>该脚本给出错误，非法字符串偏移..可能是因为该数组不正确。

我试图通过回显显示数组，以便您可以看到结果，您也可以尝试删除1。

这是print_r（$ shops）的结果，如果xml文件有2 <shop>;

请给我们提供完整的错误信息，暗示它指向的代码行（我们无法像访问文件名和行号一样） – Calimero

@AlivetoDie抱歉$限制只是一个额外的参数，它没用，我编辑了内容。我还添加了完整的错误。 –

@Calimero我添加了结果。再次检查 –

你需要：第一，$shops['shops']['basead']['shop']是多维数组还是不查？如果是，那么使用foreach()打印以其它方式使用echo直接象下面这样： -

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

是的，这是正确的，我必须检查是否有2个或更多的店铺计数。 –

谢谢！我现在将尝试重新运行我的脚本，并在其中进行更正。 –

@JohnDaleOcayaAndilDale很乐意帮助你。请检查编辑后的答案（删除不必要的变量创建） –

你需要检查数组是一维或多维您正确的代码是

<?php 
$xml = simplexml_load_file('shop.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, $limit=1); 

function logCompanyData($shops, $limit) 
{ 
    $array_data = array(); 
    if(is_array(@$shops['shops']['basead']['shop'][0])){ 
     $array_data = $shops['shops']['basead']['shop']; 
    }else{ 
     $array_data = array($shops['shops']['basead']['shop']); 
    } 
    foreach ($shops['shops']['basead']['shop'] as $company) 
    { 
     // /echo "<pre>"; print_r($company); die(); 
     $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 />'; 
    } 
} 
?>

从错误中逃脱是不正确的。不要逃跑，试着找到它并解决它。 –

'可能由该表达式生成的任何错误消息将被忽略 - >为什么要忽略，如果你可以解决它？那么你是否总是留下通知，并警告它？ –
