File management with DooFile

[ximian]

but filesize only works for files, so would need to recursively get all the file size in the folder and get the sum out of it.

That's why i said that we should have a Directory class to handle all directory stuff. This way you can group all directory functions together and eg, when you do a directory listing cycle, that method could be smart to return objects (of type directory, file, image) instead of just strings. This way you could apply some tasks recursively.
Anyway, here goes the directory::getSize

Code: Select all

        function getSize( $recursive = false, $formatted = false, $decimals = 1 ) {
            $total = 0;
            $dirHandle = opendir( $this->getPath() );
            while ( false !== ( $file = readdir( $dirHandle ) ) ) {
                if ( $file == '.' || $file == '..') {
                    continue;
                }
                if ( is_file( $this->getPath() .'/'. $file ) ) {
                    $total += filesize( $this->getPath() .'/'. $file );
                } else if ( $recursive && is_dir( $this->getPath() .'/'. $file ) ) {
                    $subdir = new Directory( $this->getPath() .'/'. $file );
                    $total += $subdir->getSize(true, false, $decimals);
                }
            }
            closedir( $dirHandle );
            if ( ! $formatted ) {
                return $total;
            }
            return Util::formatFilesize( $total, $decimals );
        }

        function getPath() {
            return Path::getFullPath( $this->_path );
        }


Code: Select all

        // Path class
        function getFullPath( $path ) {
            return realpath( $path );
        }

Not sure what you meant but I added getSize() where you can choose what unit(B, KB, MB, GB) to be return. And a static formatBytes() to convert bytes to other units.

Code: Select all

    /**
     * Get the space used up by a folder recursively.
     * @param string $dir Directory path.
     * @param string $unit Case insensitive units: B, KB, MB, GB or TB
     * @param int $precision
     * @return float total space used up by the folder (KB)
     */
    public function getSize($dir, $unit='KB', $precision=2){
        if(!is_dir($dir)) return filesize($dir);
        $dir = str_replace('\\', '/', $dir);
        if($dir[strlen($dir)-1] != '/'){
            $dir .= '/';
        }

        $totalSize = 0;
      $handle = opendir($dir);

      while(false !== ($file = readdir($handle))){
         if($file != '.' && $file != '..'){
                if (is_dir($dir.$file)){
               $totalSize += $this->getSize($dir.$file);
            }else{
                    $totalSize += filesize($dir.$file);
            }
         }
      }
      closedir($handle);
        return self::formatBytes($totalSize, $unit, $precision);
    }
