PDO extensions?

[Dragon Knight]

Hi,

I'm going to try out the PDO functions, cause I've been reading on PHP.net on how to retrieve data from the last row of information that was inserted into mysql using php
and I only know that PDO function can do this....unless anyone suggests a way without using PDO

anyway, I downloaded the extensions to my ext folder, the dlls are there, I also made sure the extension_dir is set to the ext location, then I enabled the extensions by using extension=php_pdo...... instead of ;extension=php_pdo....
but now it says this:

PHP Warning: PHP Startup: Unable to load dynamic library 'C:\PHP\ext\php_pdo_oci.dll' - The specified module could not be found. in Unknown on line 0 PHP Warning: PHP Startup: Unable to load dynamic library 'C:\PHP\ext\php_pdo_oci8.dll' - The specified module could not be found. in Unknown on line 0

I don't know why it is like this..the files are there, I also enabled it....but it's not found...

please help...thanks
