connection_vars_set

set all connection variables
connection_vars_set (in var_array any);
Description

Connection variables do not persist across sessions, one may maintain persistence of variables by storing them in a database table, as discussed in Session Variables -section.

Parameters
var_array – An array of even number of elements, containing name-value pairs. NULL, will cause all connection variables for current connection to be erased.
Examples
Usage
  <?vsp
