GTK2 and ffi module

Hello guys I would like to ask the PHP dev gurus ( you ) about one thing. I'm using ( I hope ) the current release from PHP5 ( for windows at the ftp at the PHP-GTK site ) and would like to load the ffi extension module. I would like to know more about this error: Warning: dl(): : Unable to initialize module Module compiled with module API=20041030, debug=0, thread-safety=1

PHP    compiled with module API=20050922, debug=0, thread-safety=1

These options need to match I'm using dl() altough i'm aware i should not to dl() but when loaded with php.ini it does the same. The ffi module is the latest from http://pecl4win.php.net/ext.php/php_ffi.dll and the PHP version of my PHP is the one from the FTP at emini Thank you for your help Regards Pedro Heliodoro
