    <para>
     Execute a query prepared by <function>ibase_prepare</function>. If 
     the query raises an error, returns &false;. If it is successful and 
     there is a (possibly empty) result set (such as with a SELECT query), 
     returns a result identifier. If the query was successful and there were 
     no results, returns &true;.
    </para>
    <para>
     This is a lot more effective than using <function>ibase_query</function>
     if you are repeating a same kind of query several times with only
     some parameters changing.

      <para>
      In PHP 5.0.0 and up, this function returns the number of rows affected by
      the query (if > 0 and applicable to the statement type). A query that succeeded,
      but did not affect any rows (e.g. an UPDATE of a non-existent record) will return
      &true;.
