dbplus_tcl -- Execute TCL code on server side

## Description

string dbplus_tcl ( int sid, string script )

警告
本函数是实验性的。本函数的行为，包括函数名称以及其它任何关于本函数的文档可能会在没有通知的情况下随 PHP 以后的发布而改变。使用本函数风险自担。

A db++ server will prepare a TCL interpreter for each client connection. This interpreter will enable the server to execute TCL code provided by the client as a sort of stored procedures to improve the performance of database operations by avoiding client/server data transfers and context switches.

dbplus_tcl() needs to pass the client connection id the TCL script code should be executed by. dbplus_resolve() will provide this connection id. The function will return whatever the TCL code returns or a TCL error message if the TCL code fails.
