dbplus_tcl -- Execute TCL code on server side
( int sid, string script )
This function is
EXPERIMENTAL. The behaviour of this function, the
name of this function, and anything else documented about this
function may change without notice in a future release of PHP.
Use this function at your own risk.
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.
