PHP is a programming language widely used for web development and can interact with a variety of database management systems (DBMS). PHP provides a series of database extensions to connect and operate various databases. Below are a few common databases that are supported in PHP.
1. MySQL: MySQL is a free and open source relational database management system that is widely used in web development. PHP provides a set of MySQL-related functions for interacting with MySQL, such as connecting, querying, inserting, updating and deleting data, etc. With the MySQL extension for PHP, developers can easily operate MySQL databases.
2. PostgreSQL: PostgreSQL is a powerful open source relational database management system with advanced features and strong SQL support. PHP provides PGSQL extension for connecting and operating PostgreSQL database. The PGSQL extension provides a set of functions to perform operations such as queries, transaction processing, prepared statements, and data type mapping.
3. SQLite: SQLite is a lightweight embedded database engine that is widely used in mobile devices and embedded systems. PHP provides a set of functions for interacting with SQLite databases through the SQLite extension. SQLite database is suitable for small projects and simple data storage needs.
4. Oracle: Oracle is a powerful commercial relational database management system that is widely used in enterprise-level applications. PHP provides the ability to connect to and operate Oracle databases through Oracle extensions. Oracle extensions enable developers to perform queries, insert, update and delete data, as well as manage connections and transactions in PHP.
5. Microsoft SQL Server：Microsoft SQL Server is a popular relational database management system that is widely used in enterprise applications in Windows environments. PHP provides a set of functions to connect to and manipulate Microsoft SQL Server database. Through PHP's sqlsrv extension, developers can perform operations such as querying, transaction processing, and data type mapping.
6. In addition to the databases listed above, PHP also supports many other databases, such as MongoDB, Redis, CouchDB, etc. With appropriate extensions, developers can interact with specific databases in PHP.
It should be noted that different database extensions need to enable the corresponding extensions in the PHP configuration file and configure them according to the connection parameters of the database. Developers should choose an appropriate database based on project requirements and database characteristics, and be familiar with the corresponding extensions and functions in order to effectively connect and operate the database in PHP .
