12.8 The InterBase Module

InterBase has until recently been a closed source database developed by Borland. But InterBase has lately joined the open source movement. More information about InterBase can be found at http://www.interbase.com/.

Explanation

The InterBase module is just like all the other modules we've discussed ”except for one oddity: It doesn't have a fetch_array() function. Therefore, in the db_fetchrow() function, we cast the return value of ibase_fetch_object() to an array that converts the object's properties into the indexes of an associative array.
