    PHP - writing a directory into an XML file

    I am having trouble writing my file directory of my website in to an XML file. I've searched all over google and have had no success with the examples that I've found. I've checked the php documentation but can't find anything really.

    here's the code i've been working with:

    PHP Code:
    $contents = "<?xml version=\"1.0\" ?>\n";
    $path "easythanks/";

    function 
    outputPath($path){
      
    $level=substr_count($path,'/');
      for (
    $i=1;$i<$level;$i++) echo '   ';
      echo 
    basename($path);
      echo 
    "\n";
    }

    echo 
    '<pre>';
    traverseDirTree('./','outputpath','outputpath');
    echo 
    '</pre>';


    function 
    traverseDirTree($base,$fileFunc,$dirFunc=null,$afterDirFunc=null){
      
    $subdirectories=opendir($base);
      while ((
    $subdirectory=readdir($subdirectories))!==false){
        
    $path=$base.$subdirectory;
        if (
    is_file($path)){
            
    $contents .= "<item text=".$path." />";
        
              if (
    $fileFunc!==null){
              
    $fileFunc($path);
          }
        }else{
            
    $contents .= "<item text=".$path.">";
          if (
    $dirFunc!==null$dirFunc($path);
          if ((
    $subdirectory!='.') && ($subdirectory!='..')){
            
            
    traverseDirTree($path.'/',$fileFunc,$dirFunc,$afterDirFunc);
            
          }
          if (
    $afterDirFunc!==null$afterDirFunc($path);
          
    $contents .= "</item>";
        }
      }
    }

    $myFile "test.xml";
    $fh fopen($myFile'a') or die("can't open file");
    fwrite($fh$contents);
    fclose($fh);
    Can anyone please point me in the right direction? PS the xml file needs to look like this

    Code:
    <item text="directory1">
                <item text="directory2">
                    <item text="child1" />
                </item>
                <item text="child2" />
                <item text="child3"/>
    </item>
    Thanks,
    David

    Re: PHP - writing a directory into an XML file

    I would normally do it via Dom

    where is you root tag?

    HTML Code:
    <?xml version="1.0" ?>
    <items>
       <item text="directory1">
          <item text="directory2">
             <item text="child1" />
          </item>
          <item text="child2" />
          <item text="child3"/>
       </item>
    </items>
    PHP Code:
    $filename "test.xml";
    $doc = new DOMDocument('1.0');
    $doc->preserveWhiteSpace false;
    $doc->Load($filename);
    $doc->formatOutput true;

    $items $doc->createElement("items");
    $doc->appendChild($items); 

    $path "easythanks/";

    function 
    outputPath($path){
       
    $level=substr_count($path,'/');
       for (
    $i=1;$i<$level;$i++) echo ' ';
       echo 
    basename($path);
       echo 
    "\n";
    }

    echo 
    '<pre>';
    traverseDirTree($items,'./','outputpath','outputpath');
    echo 
    '</pre>';

    function 
    traverseDirTree($cNode$base,$fileFunc,$dirFunc=null,$afterDirFunc=null){
       
    $subdirectories=opendir($base);
       while ((
    $subdirectory=readdir($subdirectories))!==false){
          
    $path=$base.$subdirectory;
          if (
    is_file($path)){
             
    $item $doc->createElement("item");
             
    $item->set_attribute('text'$path);
             
    $cNode->appendChild($item);

             if (
    $fileFunc!==null){
                
    $fileFunc($path);
             }
          }else{
             
    $item $doc->createElement("item");
             
    $item->set_attribute('text'$path);
             
    $cNode->appendChild($item);
             if (
    $dirFunc!==null$dirFunc($path);
             if ((
    $subdirectory!='.') && ($subdirectory!='..')){

                
    traverseDirTree($cNode,$path.'/',$fileFunc,$dirFunc,$afterDirFunc);

             }
             if (
    $afterDirFunc!==null$afterDirFunc($path);
          }
       }
    }

    $doc->save($filename); 
    Note untested code
