$basename = $path_info['basename'];
$ext = $path_info['extension'];
$dirname = $path_info['dirname'];
$filename = $path_info['filename'];
// 添加参数获取特定的值
$dir = pathinfo($path, PATHINFO_DIRNAME);   //目录
$base = pathinfo($path, PATHINFO_BASENAME); //文件名（含扩展名）
$ext = pathinfo($path, PATHINFO_EXTENSION); //扩展名
$filename = pathinfo($path, PATHINFO_FILENAME); // 文件名（不含扩展名，PHP>5.2）
