Hi

We need to scan a folder for all other folders that a re present in it. It should scan to very deep level of folders.

It then, should print sorted, numbered listed of all folders found.

 It should also ignore default "." & ".." directories.

Thanks,

try this
<?php
function showDirect( $pth = '.', $lev = 0 ){
    $ignore = array( 'cgi-bin', '.', '..' );// Directories to ignore
    $dh = @opendir( $pth );
    while( false !== ( $file = readdir( $dh ) ) ){
        if( !in_array( $file, $ignore ) ){
            $spacer = str_repeat( '&nbsp;', ( $lev * 4 ) );
            if( is_dir( "$pth/$file" ) ){
                echo "<strong>$spacer $file</strong><br />";
                showDirect( "$pth/$file", ($lev+1) );            
            } else {
                echo "$spacer $file<br />";            
            }
        }
    }
    closedir( $dh );
}
 
?> 
 
 
Calling the function
 
 
showDirect( "." );// Current directory
 
showDirect( "./this/directory" );// Show "this/directory"

it will print the directory contents recursively. the spacer variable needs to be modified to output as a list

check this page

funny little mind-game hehe.
spend a few hours trying to make it work yesterday, and heres my result.
The sort-function (sortbyname()) is quite messy and im sure it can be done easier, but it works.

Hope you can use it.
<?php
filefinder();
 
function filefinder() {
	#SELECT THE FOLDER FROM WHERE YOU
	#WILL START SEARCHING
	$topfolderpath = "myfolder";
 
	#DEFINES THE VARIABLES NEEDED
	$tree = array();
	$undone = array();
 
	#IF THIS IS THE FIRST RUN, LETS START WITH
	#THE PATH SPECIFIED
	if(count($tree) == 0) {
		dirsearch($topfolderpath, $tree, $undone);
	}
 
	#FROM NOW ON, WE CAN LET IT LOOP THROUG
	#THE FOLDERS WE HAVE SPOTTED WHILE SCANNING
	#OTHER DIRECTORIES
	while(count($undone) > 0)
	{
		foreach($undone as $id => $dir)
		{
			dirsearch($dir, $tree, $undone);
			unset($undone[$id]);
		}
	}
 
	#THE COMPLETE SET OF FOLDERS IS FOUND, BUT NEED TO BE
	#SORTED BY NAME BEFORE PRINTED.
	sortbyname($tree);
 
	#AT LAST, LETS LOOP THE CONTENT TO THE SCREEN
	foreach($tree as $id=>$element) {
		echo $id + 1 .". ". $element["name"] ."<br />";
		echo "Files found: ". $element["files"]. "<br /><br />";
 
	}
}
 
function sortbyname(&$tree) {
	#DEFINE OUR VARIABLE(S)
	$names = array();
 
	#LETS CREATE A NEW ARRAY, WITH ONLY THE NAMES
	foreach($tree as $elem) {
		$names[] = $elem["name"];
	}
 
	#TIME TOR SORT THE NEW ARRAY WE HAVE.
	#WE NEED TO HAVE IN MIND THAT THE FUNCTION IS
	#CASE-SENSITIVE, SO LETS DO A LITTLE WORKAROUND.
	$lc = array_map('strtolower', $names);
	array_multisort($lc, SORT_STRING, $names);
 
	#WHEN THE NAMES-ARRAY SORTED, ITS TIME TO FIND THE
	#REAL ARRAY SO WE CAN RE-BUILD IT.
	foreach($names as $name)
	{
		foreach($tree as $elem) {
			if($elem["name"] == $name)
				$sorted[] = $elem;
		}
	}
	#OVERWRITES THE EXISTING ARRAY
	$tree = $sorted;
}
 
function dirsearch($dir, &$tree, &$undone) {
	#INITIAL VARS
	$i = count($tree);
	$conn = opendir($dir);
	$files = 0;
 
	#LETS LOOP THROUG ALL THE CONTENT IN THE SELECTED
	#DIRECTORY
    while (false !== ($file = readdir($conn))) {
    	#WE DONT WANT TO HAVE . AND .. LISTED!
    	if($file != "." && $file != "..")
    	{
    		#IS IT A DIR OR A FILE WE FOUND?
    		#IF IT IS A DIR, WE WILL SAVE IT TEMPORARILY
    		#SO WE CAN SEARCH IT LATER.
			if(is_dir($dir ."/". $file)) {
				$undone[] = $dir."/".$file;
			}
			else
			{
				$files++;
			}
		}
    }
    closedir($conn);
 
    #WE DONT WANT ALL THE MESSY PATH INFORMATION PRINTED
    #SO LETS REMOVE IT.
	$shortname = explode("/", $dir);
	$tree[$i]["name"] = $shortname[count($shortname)-1];
 
	#ALMOST DONE, JUST HAVE TO REMEMBER TO SAVE WHAT WE CAME FOR.
    $tree[$i]["files"] = $files;
}
?>

You can use this:
<?php
echo '<ul>';
listFiles('/path/to/my/folder/');
echo '</ul>';
 
function listFiles($dir) {
	$it    = opendir($dir);
	$files = 0;
	$dirs  = array();
	while($f = readdir($it)) {
		if($f == '.' || $f == '..') {
			continue;
		}
		if(is_file($dir.'/'.$f)) {
			$files++;
		} else {
			$dirs[] = $dir.'/'.$f;
		}
	}
	
	echo '<li>'.basename($dir);
	echo '<br />Files Found: '.$files;
	if(count($dirs) > 0) {
		echo '<ul>';
		array_map('listFiles', $dirs);
		echo '</ul>';
	}
	echo '</li>';
}
