Description:
------------
The PHP interbase functions seem not to support column names that are longer than 31 characters with Interbase 8.1.  Interbase 5.5 through 6.5 are supposedly limited to 31 character names, but later version are not.

I can query the field with PHP using the full name.  The correct value is returned, but the returned name is incorrectly truncated to 31 characters.  The Interbase IBConsole program returns the correct field name, untruncated.

Reproduce code:
---------------
<?
ibase_connect(...);
ibase_query( "create table TEST1 ( A_________B_________C_________D_________E_________F_________ integer );" );
ibase_query( "insert into TEST1 values ( 1 );" );
$result = ibase_query( "select * from TEST1;" );
$object = ibase_fetch_object( $result );
var_dump( $object );
?>

Expected result:
----------------
object(stdClass)#2 (1) {
  ["A_________B_________C_________D_________E_________F_________"]=>
  int(1)
}


Actual result:
--------------
object(stdClass)#2 (1) {
  ["A_________B_________C_________D"]=>
  int(1)
}
