This article mainly shares with you several methods of php folder traversal, hoping to help everyone.

Function

function dirTree(){
    if(!is_dir($path)) return [];        $files = [];        $dir = opendir($path);        while($file = readdir($dir)) {            if($file == '.' || $file == '..') continue;            $new_path = trim($path, '/').'/'.trim($file, '/');            $files[] = $new_path;            if(is_dir($new_path)){                $files = array_merge($files, $this->ergodicDir2($new_path));
            }
        }
        closedir($dir);        return $files;
}

Directory Class

function dirTree(){
    if(!is_dir($path)) return [];        $files = [];        $dir_h = dir($path);        while($file = $dir_h->read()){            if($file == '.' || $file == '..') continue;            $new_path = trim($path, '/').'/'.trim($file, '/');            $files[] = $new_path;            if(is_dir($new_path)){                $files = array_merge($files, $this->ergodicDir3($new_path));
            }
        }        $dir_h->close();        return $files;
}

Iterator

function dirTree(){
    if(!is_dir($path)) return [];    $files = [];        $dir = new \DirectoryIterator($path);        foreach ($dir as $key => $file){            if($file->getFilename() == '.' || $file->getFilename() == '..'){                continue;
            }            $files[] = $file->getPathname();            if($file->isDir()){                $files = array_merge($files, $this->ergodicDir5($file->getPathname()));
            }
        }        return $files;
