Question

我有這個下面的代碼，它做工精細

 header ("content-type: text/xml"); 
     $xml = '<?xml version="1.0" encoding="UTF-8"?>'; 
     $xml .= '<urlset xmlns="http://www.google.com/schemas/sitepam/0.84">'; 
     $xml .= '<url><loc>'.SiteRoot.'</loc><changefreq>daily</changefreq><priority>1.0</priority></url>'; 
     $xml .= '<url><loc>'.SiteRoot.'/directory</loc><changefreq>daily</changefreq><priority>0.9</priority></url>'; 
     $Query = mysql_query ("SELECT link FROM `om` ORDER BY `link`"); 
     while($row = mysql_fetch_array($Query)) { 
      $xml .= '<url>'; 
      $xml .= '<loc>'.GenerateLink('link',$row['link']).'</loc>'; 
      $xml .= '<changefreq>weekly</changefreq>'; 
      $xml .= '<priority>0.8</priority>'; 
      $xml .= '</url>'; 
     } 
     $xml .= '</urlset>'; 
     echo $xml; 

當我嘗試用MIME頭壓縮它

header('content-type: application/x-gzip'); 
header('Content-Disposition: attachment; filename="sitemap.xml.gz"'); 

瀏覽器下載.gz文件，但它不是打開。 WinRAR的給我一個錯誤說：歸檔或者是在未知的格式或損壞

這是最後的代碼：

// header ("content-type: text/xml"); 
     header('content-type: application/x-gzip'); 
     header('Content-Disposition: attachment; filename="sitemap.xml.gz"'); 
     $xml = '<?xml version="1.0" encoding="UTF-8"?>'; 
     $xml .= '<urlset xmlns="http://www.google.com/schemas/sitepam/0.84">'; 
     $xml .= '<url><loc>'.SiteRoot.'</loc><changefreq>daily</changefreq><priority>1.0</priority></url>'; 
     $xml .= '<url><loc>'.SiteRoot.'/directory</loc><changefreq>daily</changefreq><priority>0.9</priority></url>'; 
     $Query = mysql_query ("SELECT link FROM `om` ORDER BY `link`"); 
     while($row = mysql_fetch_array($Query)) { 
      $xml .= '<url>'; 
      $xml .= '<loc>'.GenerateLink('link',$row['link']).'</loc>'; 
      $xml .= '<changefreq>weekly</changefreq>'; 
      $xml .= '<priority>0.8</priority>'; 
      $xml .= '</url>'; 
     } 
     $xml .= '</urlset>'; 
     echo $xml; 

Answer 1

嘗試使用一些內置的gzip功能像gzencode

echo gzencode($xml);
