解析XML文件，跳过一个标记

我正在尝试加载xml文件并解析它。我有一个配置文件，在那里我定义了我感兴趣的名称数组，所以加载文件后，我比较标签与我预定义的数组，如果值匹配，然后使用标签(名称)作为索引到数组和保存其值。问题是，它总是跳过在配置数组中第一个名称的标记。此外，LoadCsvReport应该工作，除了少数错误检查是好的代码吗?我正在学习面向对象编程，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/>";

}
}
