What are the best practices for organizing and searching through a complex folder structure in PHP?

When dealing with a complex folder structure in PHP, it is important to use a systematic approach for organizing and searching through the files. One way to do this is by creating a recursive function that traverses the directory structure and performs the necessary operations on each file or folder.

function searchFiles($dir){
    $files = scandir($dir);
    
    foreach($files as $file){
        if($file == '.' || $file == '..'){
            continue;
        }
        
        $path = $dir . '/' . $file;
        
        if(is_dir($path)){
            searchFiles($path);
        } else {
            // Perform operations on the file here
            echo $path . "\n";
        }
    }
}

// Call the function with the root directory
searchFiles('/path/to/directory');
