php-"PHP" uchome how to get free space when uploading video

uchomephp

Just graduated from work for 4 months, not much contact, the recent company a project with Uchome, completely do not understand where is where, want to ask you, in the upload video when the query appears in the user's free space?

        $userid = $_POST['supe_uid'];        $space = getspace($userid);        $maxattachsize = checkperm('maxattachsize');//单位MB        echo 'maxattachsize：'.$maxattachsize.'addsize:'.$space['addsize'].'attachsize:'.$space['attachsize'].'filesize:'.$FILE['size'];exit;        if($maxattachsize) {//0为不限制            if($space['attachsize'] + $FILE['size'] > $maxattachsize + $space['addsize']) {                echo "剩余空间不足，上传失败";                exit;            }        }

$space [' addsize '] seems to be the user's personal extra space, but what about the user group's space? Is that the $maxattachsize? But this is set to 1 m, it is also 200M ...
