1.ODBC connecting MySQLWhat is ODBC first?Open Database Interconnect (CONNECTIVITY,ODBC) is an integral part of the database in the Microsoft Open Service Architecture (Wosa,windows Open Services Architecture). It establishes a set of specifications and provides a set of standard APIs (application programming interfaces) for database access. These APIs use SQL to accomplish most of their tasks. ODBC itself also provides support for the SQL language, which allows users to send SQL statements dire

PDO controls and connects to databases, and pdo controls databases. PDO (PHP Data Objects) is an interface used to connect to the database in PHP. PDO and mysqli have been recommended to replace mysql-related functions used in PHP. This is based on the security of database usage, because the latter lacks protection against SQL data hidden codes. PDO is another method for connecting to the database. Previously, mysqli was used.
