对于myisam数据库，可以控制事务的进行：
$mysqlrl = mysql_connect ( $db_config ["host"], $db_config ["user"], $db_config ["pass"], true ); if (! $mysqlrl) { $msg = mysql_error (); die ( 'Could not connect: ' . $msg ); } mysql_select_db ( $db_config ["data"], $mysqlrl ) or die ( "error: 数据库异常" ); mysql_query ( "SET NAMES 'utf8'" ); date_default_timezone_set ( 'Asia/Shanghai' ); /** * 事务操作过程 BEGIN COMMIT END */ mysql_query ( 'BEGIN' ); $flag3 = mysql_query ( $sql3); $flag1 = mysql_query ( $sql1); $flag2 = mysql_query ( $sql2); if ($flag1 && $flag1 && $flag3) { mysql_query ( 'COMMIT' ); mysql_query ( 'END' ); $data .= "\r\n" . "更新记录成功"; write_file ( $file, $data ); return true; } else { print mysql_error (); mysql_query ( 'ROLLBACK' ); mysql_query ( 'END' ); $data .= "\r\n" . "更新记录失败(⊙o⊙)！！！"; write_file ( $file, $data ); return false; } }
