PHP接收文件

$pk = $_POST['pk'];$id = 1;$infosql = "select * from `bst_hist` where id='" . $id . "'";$queryinfo = mysql_query($infosql, $conn);$rshist = mysql_fetch_array($queryinfo);if ($pk == 'aa'){echo "1";$cs = $rshist['hist'] + 1;$sqlcs = "update `bst_hist` set hist=$cs where id='" . $id . "'";mysql_query($sqlcs, $conn);}elseif($pk == 'bb'){echo "2";$cs = $rshist['hist'] + 1;$sqlcs = "update `bst_hist` set hist=$cs where id='" . $id . "'";mysql_query($sqlcs, $conn);}else{echo "0";}?>
