代码：

/*@desc：获取路径信息@param path 传入路径，如a/b/c.jpg@return info dir:路径，name:文件名，suffix:后缀名 */function fileinfo($path){$dir = dirname($path);$name = basename($path);$suffix = pathinfo($path,PATHINFO_EXTENSION);$info = array( 'dir'=>$dir, 'name'=>$name, 'suffix'=>$suffix );return $info;}测试：

$ret = fileinfo('a/b/c.jpg');var_dump($ret);输出：

array(3) {["dir"]=>string(3) "a/b"["name"]=>string(5) "c.jpg"["suffix"]=>string(3) "jpg"}
