Recurse through a directory with PHP

The PHP code below goes through a directory/folder recursively and display the files found as HTML links on a web page.

// Configuration
$cDrivePath = "C:\\inetpub\\site3\\filelibrary\\"; // Be sure to include slash at the end!
$webPath = "/filelibrary/"; // Be sure to include slash at the end!
// End configuration

function cleanUpFileName($fName, $removeThisString) {
	$ret = $fName;
	$ret = str_replace($removeThisString, "", $ret);
	$ret = str_replace("\\", " > ", $ret);
	return $ret;
}

function printDirContents(
		$path, 			// This is the HDD path to recurse into
		$cDrivePath, 	// Always carry the $cDrivePath value; used for beautifying text
		$webPath		// Always carry the $webPath value; used for beautifying text
	) {

	// Make sure we have a trailing slash and asterix
	$path = rtrim($path, "\\") . "\\*";

	// Make an array to hold all the sub-directories
	$dirs = glob($path, GLOB_ONLYDIR);
	
	// Make an array to hold all the files
	$files = glob($path); //This contains both sub-directories and files
	$files = array_diff($files, $dirs); // Remove sub-directories from the array
	
	// Print files
	foreach ($files as &$f) {
		$fnDownload = str_replace($cDrivePath, "", $f);
		$fnDisplay = cleanUpFileName($f, str_replace("*","",$path));
		print("[a href='".$webPath.$fnDownload."']".$fnDisplay."[/a]");
	}
	
	// Recurse into sub-directories
	foreach ($dirs as &$d) {
		print("[h3]".(cleanUpFileName($d, $cDrivePath))."[/h3]";
		// Print folder
		printDirContents($d, $cDrivePath, $webPath);
	}
}
$displayArray = printDirContents($cDrivePath, $cDrivePath, $webPath);
