How to implement mysql transaction processing in php, phpmysql transaction processing
The example in this article describes the method of implementing mysql transaction processing in PHP. Share it with everyone for your reference. The specific analysis is as follows:
The prerequisite for realizing this function is that the environment mysql 5.2/php 5 supports transaction table types and requires InnoDB. With these conditions, you can implement the above. This transaction rollback operation is often used in large projects. , will be used in banks, e-commerce, etc. Friends in need can refer to it.
Recently, the project software has been upgraded to support transaction processing. Here is an example for everyone to learn and refer to.
Environment mysql 5.2 /php 5
Table type that supports transactions requires InnoDB
php mysql transaction processing implementation program code is as follows:
mysql_select_db('web_his',$LinkID);
mysql_query("set names utf8");
/* Create transaction */
mysql_query('START TRANSACTION') or exit(mysql_error());
$ssql1="insert into pf_item values('22','we','30')"; //Execute sql 1
if(!mysql_query($ssql1)){
echo $ssql1.mysql_errno().":".mysql_error()."
";
Mysql_query('ROLLBACK') or exit(mysql_error());//Determine rollback when execution fails
exit;
}
$ssql1="insert into pf_item values('21','hell','10')"; //Execute sql 2
if(!mysql_query($ssql1)){
echo $ssql1.mysql_errno().":".mysql_error()."
";
Mysql_query('ROLLBACK') or exit(mysql_error()); // Determine rollback when execution fails
exit;
}
mysql_query('COMMIT') or exit(mysql_error());//Execute transaction
mysql_close($LinkID);
?>
I hope this article will be helpful to everyone’s PHP programming design.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

Apache connects to a database requires the following steps: Install the database driver. Configure the web.xml file to create a connection pool. Create a JDBC data source and specify the connection settings. Use the JDBC API to access the database from Java code, including getting connections, creating statements, binding parameters, executing queries or updates, and processing results.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

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 uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.
