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 is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.
