This document provides examples of using various sqlsrv PHP functions including sqlsrv_begin_transaction(), sqlsrv_cancel(), sqlsrv_client_info(), sqlsrv_close(), and sqlsrv_commit(). The examples show connecting to a SQL Server database, executing queries within transactions, retrieving client information, closing connections, and committing or rolling back transactions based on query results.
