PHP Code:

function getDirectory( $path = '.'){      
    
    $ignore = array( 'cgi-bin', '.', '..' );
    // Directories to ignore when listing output. Many hosts
    // will deny PHP access to the cgi-bin.

    $dh = @opendir( $path );
    // Open the directory to the handle $dh
    
    while( false !== ( $file = readdir( $dh ) ) ){
    // Loop through the directory
        
        if( !in_array( $file, $ignore ) ){
        // Check that this file is not to be ignored
            
            // Just to add spacing to the list, to better
            // show the directory tree.
            
            if( is_dir( "$path/$file" ) ){
            // Its a directory, so we need to keep reading down...
            
                               
                //Add a class as selector for the jQuery sorting later.
                echo "<li>$file<ul class='has-children'>"; 
                getDirectory( "$path/$file");
                // Re-call this same function but on a new directory.
                // this is what makes function recursive.
                echo "</li>";
            
            } else {
            
                echo "<li>$file</li>";
                // Just print out the filename
            
            }
            
            
        
        }
        
    
    
    }
    echo "</ul>";
    closedir( $dh );
    // Close the directory handle

}
//Add a class as selector for the jQuery sorting later.
echo "<ul class='has-children'>";
getDirectory( "." ); 


Then add the following jQuery codes to sort the lists:

<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
$(function() {   
$('ul.has-children').each(function() {
	var $t=$(this);
	var Li=$t.find('>li').get();
	Li.sort(function(a, b) {
             var A = $(a).text().toUpperCase();
             var B = $(b).text().toUpperCase();
             if (A < B) return -1;    // changing to 1 to sort in DESC order...
             if (A > B) return 1;     // changing to -1 to sort in DESC order...
           return 0;
        });
	 $.each(Li,function(i,v) {
	      $t.append(v);
	  });
});
</script>

Have fun

Here is the PHP way to do the same sorting as the above with jQuery:

PHP Code:

<?
$tree=array();

function getDirectory( $path = '.'){      
    
    $ignore = array( 'cgi-bin', '.', '..' );
    // Directories to ignore when listing output. Many hosts
    // will deny PHP access to the cgi-bin.

    $dh = @opendir( $path );
    // Open the directory to the handle $dh
    
    //Make counter
    $j=0;
    $temp=array();
        
    while( false !== ( $file = readdir( $dh ) ) ){
    // Loop through the directory
        
        if( !in_array( $file, $ignore ) ){
        // Check that this file is not to be ignored
            
            // Feed with file name           
            $temp[$j]['name']=$file;
            
            if( is_dir( "$path/$file" ) ){
            // Its a directory, so we need to keep reading down...    
               $temp[$j]['children']=getDirectory( "$path/$file");
            } 
       
        }
        
       $j++; //counting
    
    }
    return $temp;
   
    closedir( $dh );
    // Close the directory handle

}//end of function

//Put the file directory system in an array first...
$tree=getDirectory("/your-dirtory/here");

$type='desc'; //set sorting type 'desc' or 'asc'


//recursive function for sorting arrays
function getSort(&$temp) {
 global $type;

 switch ($type) {
      case 'desc':
      rsort($temp);
      break;
      case 'asc':
      sort($temp);
      break;
}
     
 foreach($temp as &$t) {
   if(is_array($t['children']))
                       getSort($t['children']);
 }
} //end of function

//Go through arrays again for sorting...now we have new sorted array $tree...     
getSort($tree);
?>
<pre>
<?
print_r($tree);  // output 
?>
</pre>
