PHP + SQLite = tearing hairs..

Hello,

I've spend some days on googling, but as for now - without any effect.

----------
The configuration follows:
- Windows 7 64bit (build 7100)
- PHPInfo -> Apache/2.2.13 (Win32) PHP/5.3.0
          PDO drivers 	mysql, odbc, sqlite

        PDO Driver for SQLite 3.x	enabled
        SQLite Library 	3.6.15

SQLite3 support	enabled
SQLite3 module version 	0.7-dev
SQLite Library 	3.6.15

                                                                    Directive	Local 
Value	Master Value
sqlite3.extension_dir	E:\Program Files (x86)\PHP\ext	E:\Program Files 
(x86)\PHP\ext
---------------
php.ini has the following two lines:
[PHP_PDO_SQLITE]
extension=php_pdo_sqlite.dll
[PHP_SQLITE3]
extension=php_sqlite3.dll

both DLL's are in ext folder.
------
Everything works fine, till I wanted to embed database support.  On 
sqlite_open() I get the infamous:
"Fatal error: Call to undefined function sqlite_open()"

(trying 1 argument and/or 3 arguments function call)

I start to wonder if it is compatible with 64bit system, but everything 
looks loaded and properly configured.
Help..?
