dbplus_tcl
(PHP 4 >= 4.0.7, PECL dbplus:0.9)
dbplus_tcl — Execute TCL code on server side
說明
string dbplus_tcl
( int $sid
, string $script
)
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.
