HomeBackend DevelopmentPHP TutorialPHP encapsulated MSSql operation class and complete example analysis

This article mainly introduces the MSSql operation class encapsulated by PHP, and analyzes various commonly used mssql database operations encapsulated by PHP in the form of complete examples, including the connection, addition, deletion, modification, and query for mssql database. Friends who need it can For reference,

is as follows:
