Binds variables to a prepared statement for result storage

`bool` `maxdb_stmt::bind_result` `mixed` `var1` `mixed``...`

`maxdb_stmt_bind_result` is used to associate (bind) columns in the result set to variables. When `maxdb_stmt_fetch` is called to fetch data, the MaxDB client/server protocol places the data for the bound columns into the specified variables `var1, ...`.

Note that all columns must be bound prior to calling `maxdb_stmt_fetch`. Depending on column types bound variables can silently change to the corresponding PHP type.

A column can be bound or rebound at any time, even after a result set has been partially retrieved. The new binding takes effect the next time `maxdb_stmt_fetch` is called.
