我有这个xml文档：

我可以解析图片，目的地，酒店，期限，期限，期限等，但我无法解析机场和照片，因为项目数量不同。

我的PHP代码

如何为照片和机场编制foreach程序？谢谢大家的帮助。

我改变了你的代码并使用了一些函数。看看吧。

<?php

$xml = simplexml_load_file('offer.xml');

function renderOffer($xml){
    $output = '';
    foreach ($xml->offer as $offer)
        $output .= '<tr>
      <td><img src='. $offer->image .' width="100"></td>
      <td>'. $offer->destination->country .'</td>
      <td>'. $offer->destination->locality .'</td>
      <td><a href="'. $offer->hotelinfo->url .'">'. $offer->hotel .'</a>, '. $offer->hotelinfo->stars .'*</td>
      <td>'. $offer->term->from .'</td>
      <td>'. $offer->term->to .'</td>
      <td>'. $offer->term->length .'</td>    
      <td>'. $offer->totalprice .',- Kč</td>
      <td>'. $offer->discount .'%</td>
      <td>'. $offer->food .'</td>
      <td>'. $offer->transportation .'</td>
      <td>'. renderAirports($offer->airports) .'</td>
    </tr>';
    return $output;
}

function renderAirports($airports){
    $output = '';
    foreach ($airports as $letiska)
        $output .= $letiska->airport;
    return $output;
}
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
  <meta http-equiv="content-type" content="text/html; charset=utf-8">
  <title>XML feed</title>
  </head>
  <body>

<table width='100%'>
  <thead>
    <tr>
      <th>Snímka</th>
      <th>Stát</th>
      <th>Destinace</th>
      <th>Hotel</th>
      <th>Od</th>
      <th>Do</th>
      <th>Počet dní</th>
      <th>Cena</th>
      <th>Sleva</th>
      <th>Jídlo</th>
      <th>Doprava</th>
    </tr>
  </thead>
  <tbody>
<?php print renderOffer($xml); ?>
  </tbody>
</table>    
  </body>
</html>

在tbody块

中显示

<tr>
      <td><img src=http://dsc.invia.cz/img/affil-450x300/2014/7/10/d0/4756588.jpg width="100"></td>
      <td>Egypt</td>
      <td>Hurghada</td>
      <td><a href="http://hotel.invia.cz/egypt/hurghada/three-corners-sunny-beach-resort/?aid=533153">Three Corners Sunny Beach</a>, 4*</td>
      <td>2015-07-29</td>
      <td>2015-08-05</td>
      <td>8</td>
      <td>15290,- Kč</td>
      <td>0%</td>
      <td>All Inclusive</td>
      <td>Letecky</td>
      <td>Praha</td>
    </tr>

XML解析到HTML表 - 显示所有类别
