Good day to you all,
I have a piece of code which read a directory and return a list of file and folders that is with in recursively.

This code is very slow.
Maybe you can help me make it go faster ?



<!doctype html public "-//w3c//dtd html 3.2//en">


<?php

function CountDir($aDir, $aRecurse)
{
$Count = 0;

$d = dir($aDir);

while ($Entry = $d->Read())
{
if (!(($Entry == "..") || ($Entry == ".")))
{
if (Is_Dir($aDir . '/' . $Entry))
{
if ($aRecurse)
{
$Count += CountDir($aDir . '/' . $Entry, $aRecurse);
}
}
else
{
$Count++;
}
}
}

return $Count;
}



function getDirectory( $path = '.', $level = 0 ){




$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

$spaces = str_repeat( '&nbsp;', ( $level * 4 ) );
// Just to add spacing to the list, to better
// show the directory tree.

$rest = substr($file, 0, -4);

if( is_dir( "$path/$file" ) ){
// Its a directory, so we need to keep reading down...

echo '<tr><td align="left"><a href="'.$path.'/'.$file.'" align="left" class="white00" target="image">'.$spaces.'<img src="folder_icon.gif" border="0"> '.$file.'</a> - '.CountDir($path.'/'.$file, False).' </td></tr>';





getDirectory( "$path/$file", ($level+1) );
// Re-call this same function but on a new directory.
// this is what makes function recursive.

} else {



// Just print out the filename

}
}
}
closedir( $dh );
// Close the directory handle
}

getDirectory( "." );
// Get contents of the "files/includes" folder

?>


Thanks !
