$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; } } |
