Duplicate files in php - php

Question

I am wondering how I can create a function that states:
if a file of name Setup.php exist twice in a folder and/or it's associated sub folders, return a message. if a file with the extension .css exists more then once in a folder or any of its sub folders, return a message
This function would have to be recursive, due to sub folders. and its fine to hard code 'Setup.php' or '.css' as they are the only things looked for.
What I currently have is a bit messy but does the trick (refactoring will come after I figure out this issue)
protected function _get_files($folder_name, $type){
$actual_dir_to_use = array();
$array_of_files[] = null;
$temp_array = null;
$path_info[] = null;
$array_of_folders = array_filter(glob(CUSTOM . '/' .$folder_name. '/*'), 'is_dir');
foreach($array_of_folders as $folders){
$array_of_files = $this->_fileHandling->dir_tree($folders);
if(isset($array_of_files) && !empty($array_of_files)){
foreach($array_of_files as $files){
$path_info = pathinfo($files);
if($type == 'css'){
if($path_info['extension'] == 'css'){
$actual_dir_to_use[] = $folders;
}
}
if($type == 'php'){
if($path_info['filename'] == 'Setup' && $path_info['extension'] == 'php'){
$temp_array[] = $folders;
$actual_dir_to_use[] = $folders;
}
}
}
}
$array_of_files = array();
$path_info = array();
}
return $actual_dir_to_use;
}
if you pass in say, packages and php into the function I will look through the packages folder and return all the sub-folder names, (eg: path/to/apples, path/to/bananas, path/to/fruit, path/to/cat, path/to/dog) that contain Setup with an extension of php.
The problem is if apples/ contains more then one Setup.php then I get: path/to/apples, path/to/apples, path/to/bananas, path/to/fruit, path/to/cat, path/to/dog
So I need to modify this function, or write a separate one, that sates the above sudo code.
problem? I don't know where to begin. So I am here asking for help.

You can find the class ipDirLiterator here - deleting all files in except the one running the delete code.
i hope you got it.
<?php
$directory = dirname( __FILE__ )."/test/";
$actual_dir_to_use = array();
$to_find = "php";
$literator = new ipDirLiterator( $directory, array( "file" => "file_literator", "dir" => "dir_literator" ) );
$literator->literate();
function file_literator( $file ) {
global $actual_dir_to_use, $to_find;
// use print_r( $file ) to see what all are inside $file
$filename = $file["filename"]; // the file name
$filepath = $file["pathname"]; // absolute path to file
$folder = $file["path"]; // the folder where the current file contains
$extens = strtolower( $file["extension"] );
if ( $to_find === "php" && $filename === "Setup.php" ) {
$actual_dir_to_use[] = $folder;
}
if ( $to_find === "css" && $extens === "css" ) {
$actual_dir_to_use[] = $folder;
}
}
function dir_literator( $file ) {}
print_r( $actual_dir_to_use );
// or check
if ( count( $actual_dir_to_use ) > 1 ) {
// here multiple files
}
?>

Q: Is this a homework assignment?
Assuming "no", then:
1) No, the function doesn't need to be recursive
2) Under Linux, you could find matching files like this: find /somefolder -name somefile -print
3) Similarly, you can detect if a match occurs zero, once or more than once in the path like this:
find /somefolder -name somefile -print|wc -l
