Hi, i've reinstalled PHP 5.2.6 on my windows XP x64 and as usual i uncomment the following lines: extension=php_mysql.dll extension=php_pdo.dll extension=php_pdo_mysql.dll extension=php_pdo_pgsql.dll extension=php_pdo_sqlite.dll extension=php_pgsql.dll extension=php_sqlite.dll extension=php_dbg.dll-5.2.x after restaring the whole server apache+postgresql + php, i run a simple phpinfo() and i see nowhere anything about postgresql module or PDO. phpinfo show that it runs based on the php.ini from D:\webserver\php folder and not from c:\windows. which is correct as my php.ini is the the D:\webserver\php folder. so where could be the problem ? thx. -- Alain ------------------------------------ Windows XP x64 SP2 PostgreSQL 8.3.5 / MS SQL server 2005 Apache 2.2.10 PHP 5.2.6 C# 2005-2008
