What is the $bind_args for in ibase_query()?

[jumpfroggy]

I'm using Interbase (not by choice) on a new project and I'm not familiar with it (normally I use MySQL, Postgresql, etc).

I'm using this:

resource ibase_query  ([ resource $link_identifier  ], string $query  [, int $bind_args  ] )

But the manual completely ignores $bind_args parameter.  Does anyone know what this does?

 

I've got a bunch of small questions that are only loosely related (ie. a question about quoting identifiers in ibase_execute()).  Is it better to post a lot of topics, one for each question?  Or should I lump a few together?  Thanks all.
