解析XML文件，跳过一个标记

Question

我想加载一个xml文件并解析它。我有一个配置文件，我在其中定义了我感兴趣的名称的数组，因此在加载文件后，我将标记与预定义数组进行比较，如果值匹配，则使用标记（名称）作为数组的索引并保存其值。问题在于它总是跳过配置数组中第一个名称的标签。此外，LoadCsvReport应该工作，除了几个错误检查是好代码？我正在学习OOP，但我认为我没有使用它。

class LoadAdReport extends CI_Controller 

{ 

/* 
* @return array[][] 
* */ 
public function LoadCsvReport() 
{ 
    require "config.php"; 
    $key = array(); 
    $values = array(); 
    $flag = false; 


    $csvfile = fopen(dirname(__FILE__) . "/result.csv", "r"); 

    while ($file = fgetcsv($csvfile)) { 
     if (!$flag) { 
      /*Loop through config array which contains names of columns of our interest 
       If row from file contains name from config, then that name will have assigned 
       index of that column 
      */ 
      foreach ($bing as $name) 
       if ($value = array_search($name, $file)) { 
        $key[$name] = $value; 
        $flag = true; 
       } 
      //After column indexes are assigned to names skip current row 
      if ($flag) 
       continue; 
     } 


     if ($flag) { 

      foreach ($key as $columnName => $index) { 
       /*Get columnname and index, items from $file[$index] are assign to array 
        corresponding array with columnName as index 
       */ 
       if ($file[$index] === "-") 
        break; 
       $values[$columnName][] = $file[$index]; 
       //$key[$index] = array($item => $file[$item]); 

      } 
     } 
    } 
    foreach ($values as $key => $val) 
     foreach ($val as $lol => $item) 
      echo $key . "=>" . $item . "<br/>"; 

    fclose($csvfile); 
} 

public function LoadXmlReport() 
{ 
    require "config.php"; 


    $items = array(); 
    $xmlfile = simplexml_load_file(dirname(__FILE__) . "/xmlfile.xml"); 
    foreach ($xmlfile as $key => $value) 
     foreach ($value as $key => $item) { 
      if ($item == "-") { 
       break; 
      } elseif (array_search($key, $bing)) 
       $items[$key][] = $item; 
     } 


    foreach ($items as $key => $val) 
     foreach ($val as $lol => $item) 
      echo $key . "=>" . $item . "<br/>"; 


} 
} 

这是我的XML文件

，这是我的配置文件

$bing = array(
"Adgroup", 
"Campaign", 
"Keyword", 
"Clicks", 
"Impr.", 
"Conv.", 
"Bid", 
);

的问题是在这里：

elseif (array_search($key, $bing)) 

arrach_search返回数组功能索引在哪里p当时的价值被发现。对于阵列中的第一项，即0。但是if(0)等于if(false)。

你需要返回值0区分了“我已经找到了该项目的数组中的第0位置”和‘我还没有发现在阵列中所有项目’的返回值false：

正确：

elseif (array_search($key, $bing) !== FALSE)
