PHP is a widely used server-side scripting language mainly used for web development. In web applications, data backup and recovery are very important because they protect the application's data security and prevent data loss.
PHP provides many data backup and recovery technologies, including using the backup and restore functions that come with the database management system (DBMS), using PHP extensions, using third-party libraries and tools, etc. This article will explore data backup and recovery technology in PHP and explain its advantages and disadvantages.
