Connection pooling limits the number of connections opened with the database and instead reuses a pool of existing active connections, thereby significantly enhancing the performance of PHP applications. When a PHP script needs to communicate with the database, it borrows a connection from this pool, performs the operations, and then returns it back to the pool. Although PHP doesn't have native support for connection pooling, it can be achieved through third-party tools like 'pgBouncer' when using PostgreSQL or 'mysqlnd_ms' plugin with MySQL.
