有意思的一个操作实例(需要在linux环境下跑)-PHP

=0  AND $unit/1024 1024 AND $unit/1024 <= 1024*1024 ) {
			$unit = 'M';
		} else {
			$unit = 'G';
		}
	}
	switch(strtolower($unit)) {
		case 'k':
			$size = ($size/1024);
			$suffix = 'KB';
			break;
		case 'm':
			$size = ($size/1024/1024);
			$suffix = 'MB';
			break;
		case 'g':
			$size = ($size/1024/1024/1024);
			$suffix = 'GB';
			break;
	}
	$size = sprintf("%.2f%s", $size, $suffix);
	return $size;
}

$path = 'min';
var_dump(_dirSize($path, FALSE));
var_dump(_dirSize($path, TRUE));
var_dump(_getDirCount($path));
