i might doing wrong too, plz let me know best way create xml.

there many ways this, prefer use php "template engine" when writing html or xml (or *ml matter).

    <?php echo "<?xml version=\"1.0\" encoding=\"utf-8\" ?> " ?>     <?php       $news_articles = new c7_news();       $db = c7_bootstrap::getdb();       $foxsport_sql = "select headline, link c7_news                     source = 'foxsports' , category = 'breaking news'                     limit 0,4";       $foxsport_rowset = $db->fetchall($foxsport_sql);     ?>     <data>       <news>       <?php foreach($foxsport_rowset $foxsport_row):         <title>           <description>             <![cdata[             <?php echo $foxsport_row['headline'] ?>             ]]>           </description>           <link><?php echo $foxsport_row['link']</link>         </title>       <?php endforeach; ?>       </news>     </data> 

this output xml , lot easier read

but dont know how save formed xml in file.

as how save file should have php file include "template" (suppose template called xml_template.php):

    ob_start();     include dirname(__file__) . directory_separator . 'xml_template.php';     $output = ob_get_clean(); 

then have again xml string on $output variable , can noted vlad.p:

    // if file missing, create it.     $file = fopen("file.xml", "w");     fwrite($file, $output);      fclose($file);
