<para>
Commits a transaction that was begun with <function>sqlsrv_begin_transaction</function>.
The connection is returned to auto-commit mode after <function>sqlsrv_commit</function>
is called. The transaction that is committed includes all statements that were
executed after the call to <function>sqlsrv_begin_transaction</function>.
Explicit transactions should be started and committed or rolled back using these
functions instead of executing SQL statements that begin and committ/roll back
transactions. For more information, see
<link xlink:href="&url.sqlsrv.transaction.handling;">SQLSRV Transactions</link>.
