php - How do I set main URL a priority of 1.0 and subdirectory urls priority of 0.5 in sitemap.xml -


how can make root index in sitemap priority of 1.0 , rest of sub directory files priority of 0.5?

i'm using php code generate sitemap on fly when page accessed.

as right now, gives priority of whatever set value is

$url -> appendchild( $priority = $xml->createelement('priority', '0.5') );

for every url in sitemap in example:

sitemap example

php code creates sitemap:

<? $ignore = array( 'images', 'css', 'includes', 'cgi-bin', 'xml-sitemap.php' );    function getfilelist($dir, $recurse=false) {   global $ignore;      $retval = array();      // open pointer directory , read list of files     $d = @dir($dir) or die("getfilelist: failed opening directory $dir reading");     while ( false !== ( $entry = $d->read() ) ) {          // check if dir needs ignored, if so, skip it.         if ( in_array( utf8_encode( $entry ), $ignore ) )             continue;        // skip hidden files       if($entry[0] == ".") continue;       if(is_dir("$dir$entry")) {         $retval[] = array(           "name" => "$dir$entry/",           "type" => filetype("$dir$entry"),           "size" => 0,           "lastmod" => filemtime("$dir$entry")         );         if($recurse && is_readable("$dir$entry/")) {           $retval = array_merge($retval, getfilelist("$dir$entry/", true));         }       } elseif(is_readable("$dir$entry")) {         $retval[] = array(           "name" => str_replace('./','/', $dir),           "type" => mime_content_type("$dir$entry"),           "size" => filesize("$dir$entry"),           "lastmod" => filemtime("$dir$entry")         );       }     }     $d->close();      return $retval;   }    $dirlist = getfilelist("./", true);        // sitemap creation     $time  = time();     $sitemap = $_server['document_root'].'/sitemap.xml';     if ($time - filemtime($sitemap) >= 1) { // 1 days          $xml = new domdocument('1.0', 'utf-8');          $xml->formatoutput = true;           // creating base node         $urlset = $xml->createelement('urlset');          $urlset -> appendchild(             new domattr('xmlns', 'http://www.sitemaps.org/schemas/sitemap/0.9')         );              // appending document         $xml -> appendchild($urlset);          // building xml document website content         foreach($dirlist $file)         {         if($file['type'] != 'text/x-php') continue;             //creating single url node             $url = $xml->createelement('url');               //filling node entry info             $url -> appendchild( $xml->createelement('loc', 'http://www.airsahara.in'.$file['name']) );              $url -> appendchild( $lastmod = $xml->createelement('lastmod', date('y-m-d', $file['lastmod'])) );              $url -> appendchild( $changefreq = $xml->createelement('changefreq', 'monthly') );              $url -> appendchild( $priority = $xml->createelement('priority', '0.5') );               // append url urlset node             $urlset -> appendchild($url);          }         $xml->save($sitemap);     } // if time        ?>

i'm answering own question because figured out.

i did this. took line of code , expanded if , else statement.

went this

$url -> appendchild( $priority = $xml->createelement('priority', '0.5') );

to this

    if($file['name'] != '/') {     $url -> appendchild( $priority = $xml->createelement('priority', '0.5') );     } else {         $url -> appendchild( $priority = $xml->createelement('priority', '1.0') );     }

update: per comments of hakre

        if ($file['name'] != '/') {             $p = '0.5';             } else {                 $p = '1.0';             }         $url -> appendchild( $priority = $xml->createelement('priority', $p) );

and shorthand of if else statement

        $file['name'] != '/' ? $p = '0.5' : $p = '1.0';         $url -> appendchild( $priority = $xml->createelement('priority', $p) );
