本文实例分析了PHP的mysql事务问题。分享给大家供大家参考,具体如下:
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;
- }
- }
