PHP and Firebird

Hello. I noticed, that in the newest PHP release there was added udf file for interbase/firebird , that allows to execute php functions from sql. I got interested in it, but after few hours of trying I gave up... I use Firebidr 1.5 default instalation. I compile udf file as it is written in c file: gcc -shared php-config --includes php-config --ldflags `php-config --libs` -o php_ibase_udf.so php_ibase_udf.c ...being in ext/interbase directory. Everything compiled well. File php_ibase_udf.so was created. So I copied it to /opt/firebird/UDF and started isql as SYSDBA with some database file... And I written:

    DECLARE EXTERNAL FUNCTION CALL_PHP1
        CSTRING(100),
        CSTRING(100) BY DESCRIPTOR,
        INTEGER BY DESCRIPTOR
        RETURNS PARAMETER 2
        ENTRY_POINT 'udf_call_php1' MODULE_NAME 'php_ibase_udf';

and external function was created... So I try to use this function... SQL> update FAKTURA set numer =CALL_PHP1('ucwords',numer); Statement failed, SQLCODE = -902 Access to UDF library "libphp_ibase_udf.so" is denied by server administrator So I renamed php_ibase_udf.so to libphp_ibase_udf.so and tried again...update FAKTURA set numer =CALL_PHP1('ucwords',numer); Statement failed, SQLCODE = -104 invalid request BLR at offset 16 -function CALL_PHP1 is not defined -module name or entrypoint could not be found SQL> And that's it.... I do not know what to do next... :( Can You help me? Another question is how to open transaction for two different connections. I saw in changelog that it is possible in newest version....
