Recursively searching through a directory remotely via php ftp - php

Question

I am connecting to another server via php's ftp connect.
However I need to be able to extract all html files from it's web root which is causing me a bit of a headache...
I found this post Recursive File Search (PHP) which talks about using RecursiveDirectoryIterator function however this is for a directory on the same server as the php script its self.
I've had a go with writing my own function but not sure I've got it right... assuming that the original path sent to the method is the doc root of the server:
public function ftp_dir_loop($path){
$ftpContents = ftp_nlist($this->ftp_connection, $path);
//loop through the ftpContents
for($i=0 ; $i < count($ftpContents) ; ++$i)
{
$path_parts = pathinfo($ftpContents[$i]);
if( in_array($path_parts['extension'], $this->accepted_file_types ){
//call the cms finder on this file
$this->html_file_paths[] = $path.'/'.$ftpContents[$i];
} elseif(empty( $path_parts['extension'] )) {
//run the directory method
$this->ftp_dir_loop( $path.'/'.$ftpContents[$i] );
}
}
}
}
Has anyone seen a premade class to do something like this?

You can try
public function ftp_dir_loop($path) {
$ftpContents = ftp_nlist($this->ftp_connection, $path);
foreach ( $ftpContents as $file ) {
if (strpos($file, '.') === false) {
$this->ftp_dir_loop($this->ftp_connection, $file);
}
if (in_array(pathinfo($file, PATHINFO_EXTENSION), $this->accepted_file_types)) {
$this->html_file_paths[$path][] = substr($file, strlen($path) + 1);
}
}
}
