по какой-то причине я получаю эту ошибку ниже при попытке использования нескольких функций require() в моем PHP. В принципе, я использую функции require() для доступа к парам XML-парсеров. Кто-нибудь знает, как это исправить? Если это не очень описательно, скажите ниже, и я попытаюсь исправить это. Спасибо. Я ценю любые положительные отзывы. Кроме того, я просто изучаю PHP, поэтому, пожалуйста, не слишком грубый на меня. Я приведу следующий код ниже.PHP: Неустранимая ошибка: не удается переопределить startElement()

Здесь ошибка: Фатальная ошибка: Невозможно переопределить StartElement() (ранее объявленный в /Applications/XAMPP/xamppfiles/htdocs/yournewsflow/news/sports.php:27) в/Applications/XAMPP/xamppfiles/HTDOCS /yournewsflow/news/political.php на линии 34

Here are the require functions: 

     <?php 

     require("news/sports.php"); 
     require("news/political.php"); 
     ?> 




Here is the xml parser used for a couple pages:

Вы не можете требовать того же «анализатор» более чем один раз, потому что вы уже определили функции в этом файле. Вы должны перестроить свой код:

В parser.functions.php:

function startElement($parser, $name, $attrs) { 
    global $insideitem, $tag, $title, $description, $link, $pubDate; 
    if ($insideitem) { 
     $tag = $name; 
    } elseif ($name == "ITEM") { 
     $insideitem = true; 
    } } 
function endElement($parser, $name) { 
    global $insideitem, $tag, $counter, $show, $showHTML, $outerData; 
    global $title, $description, $link, $pubDate; 
    if ($name == "ITEM" && $counter < $show) { 
     echo "<table> 
       <tr> 
        <td> 

     <a href=\"".htmlspecialchars($description)."\">".htmlspecialchars($description)."</a> 
        </td> 
       </tr>"; 


     // if you chose to show the HTML 
     if ($showHTML) { 
      $title = htmlspecialchars($title); 
      $description = htmlspecialchars($description); 
      $link = htmlspecialchars($link); 
      $pubDate = htmlspecialchars($pubDate); 

     // if you chose not to show the HTML 
     } else { 
      $title = strip_tags($title); 
      $description = strip_tags($description); 
      $link = strip_tags($link); 
      $pubDate = strip_tags($pubDate); 
     } 

     // fill the innerData array 
     $innerData["title"] = $title; 
     $innerData["description"] = $description; 
     $innerData["link"] = $link; 
     $innerData["pubDate"] = $pubDate; 

     // fill one index of the outerData array 
     $outerData["data".$counter] = $innerData; 

     // make all the variables blank for the next iteration of the loop 
     $title = ""; 
     $description = ""; 
     $link = ""; 
     $pubDate = ""; 
     $insideitem = false; 

     // add one to the counter 
     $counter++; 
    } 
} 

function characterData($parser, $data) { 
    global $insideitem, $tag, $title, $description, $link, $pubDate; 
    if ($insideitem) { 
    switch ($tag) { 
     case "TITLE": 
     $title .= $data; 
     break; 
     case "DESCRIPTION": 
     $description .= $data; 
     break; 
     case "LINK": 
     $link .= $data; 
     break; 
     case "PUBDATE": 
     $pubDate .= $data; 
     break; 
    } 
    }

Это означает, что функция startElement уже определена. У вас не может быть более одной функции с тем же именем.
