php事务处理后怎样进行页面跳转
我用的是smarty模板,中间需要一个事务处理,同时想数据库插入两条数据,而且必须是成功都成功,失败都失败。
开始我用的是mysql_query('begin');
????????????????? mysql_query($sql);
????????????????? mysql_query($sql);
然后一个if判断,都为true的话commit,否则rollback。最后
????????????????? mysql_query('end');
但是在end之后我要进行一个php页面的跳转,加上end后,end以后的php代码都不执行了,数据添加成功与否页面都不尽兴跳转了。

然后我用set autocommit??? ,把自动提交设置成手动,但是和上边情况一样。。。
?
?
后来我写了一个方法,定义一个全局变量想通过全局变量来判断是否成功,但是这个全局变量的值在方法中确实被改变了,但在方法结束后这个值没有传出来,在外边用var_dump($tranResult),一直都是一个空白的值。。。。。。
?
??? function tranType1($type,$product_name,$pic_name,$name,$diameter,$capacity,$pic){
??? ???? ??? global $tranResult;
??? ???? ???
??? ???? ??? $this->db->query('begin');
??? ???? ??? $main_id = $this->addInfoTable1($type,$product_name,$pic_name);?? //这两个是我写的添加信息的方法,返回的是mysql_insert_id()
??? ???? ??? $addTab2 = $this->addInfoTub($main_id,$name,$diameter,$capacity);
??? ???? ??? if(($main_id !== false) && ($addTab2 !== false) ){
??? ??? ??? ??? $upPic = $this->comm->checkPic($pic);
??? ??? ??? ??? if($upPic){ ???
??? ??? ??? ??? ? $this->db->query('commit');??? ??? ??? ???
??? ??? ??? ??? ? $tranResult = true;
??? ??? ??? ??? ? //var_dump($tranResult);
??? ??? ??? ??? }else{
??? ??? ??? ??? ? $this->db->query('rollback');
??? ??? ??? ??? }
??? ??? ??? }else{
??? ??? ??? ??? ?$this->db->query('rollback');
??? ??? ??? }
??? ??? ???
??? ??? ??? $this->db->query('end');
??? ??? ??? var_dump($tranResult);
??? ?}

小弟实在想不出解决的方案了,请各位大侠来帮忙解决一下,万分感谢!!!

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.

In PHP, trait is suitable for situations where method reuse is required but not suitable for inheritance. 1) Trait allows multiplexing methods in classes to avoid multiple inheritance complexity. 2) When using trait, you need to pay attention to method conflicts, which can be resolved through the alternative and as keywords. 3) Overuse of trait should be avoided and its single responsibility should be maintained to optimize performance and improve code maintainability.

Dependency Injection Container (DIC) is a tool that manages and provides object dependencies for use in PHP projects. The main benefits of DIC include: 1. Decoupling, making components independent, and the code is easy to maintain and test; 2. Flexibility, easy to replace or modify dependencies; 3. Testability, convenient for injecting mock objects for unit testing.

SplFixedArray is a fixed-size array in PHP, suitable for scenarios where high performance and low memory usage are required. 1) It needs to specify the size when creating to avoid the overhead caused by dynamic adjustment. 2) Based on C language array, directly operates memory and fast access speed. 3) Suitable for large-scale data processing and memory-sensitive environments, but it needs to be used with caution because its size is fixed.

PHP handles file uploads through the $\_FILES variable. The methods to ensure security include: 1. Check upload errors, 2. Verify file type and size, 3. Prevent file overwriting, 4. Move files to a permanent storage location.

In JavaScript, you can use NullCoalescingOperator(??) and NullCoalescingAssignmentOperator(??=). 1.??Returns the first non-null or non-undefined operand. 2.??= Assign the variable to the value of the right operand, but only if the variable is null or undefined. These operators simplify code logic, improve readability and performance.
