PHP Warings in Error Log [Pease Help]

I just opened my error log and these two errors have been constantly writing to the log for the past 30 days every few seconds:

[09-Apr-2009 12:53:46] PHP Warning: Module ‘PDO’ already loaded in Unknown on line 0
[09-Apr-2009 12:53:46] PHP Warning: Module ‘pdo_mysql’ already loaded in Unknown on line 0
[09-Apr-2009 12:53:55] PHP Warning: Module ‘PDO’ already loaded in Unknown on line 0
[09-Apr-2009 12:53:55] PHP Warning: Module ‘pdo_mysql’ already loaded in Unknown on line 0
[09-Apr-2009 12:53:56] PHP Warning: Module ‘PDO’ already loaded in Unknown on line 0
[09-Apr-2009 12:53:56] PHP Warning: Module ‘pdo_mysql’ already loaded in Unknown on line 0

How can I stop this from happening?

i think ,you should check your php.ini and search this:
extension=php_pdo_mysql.dll

and this

extension=php_pdo.dll

these lines should in the php.ini and appears only once.

I noticed that I did not have ‘extension=php_pdo_mysql.dll’ and ‘extension=php_pdo.dll’ listed within my php.ini file (in my Piwik folder) so I added these to the very bottom of the php.ini file. However, as soon as I did this, I began receiving the following error:

I am new to this level of website support so naturally I am a little confused. Any help would be appreciated.

Okay, I think I am getting closer to my problem. Where should the php.ini file live within my environment? Apparently my provider moved my php.ini folder into my Piwik folder for some reason on 3/11/09 (the same day this problem started). As a result, I do not believe my instance of Piwik knows where the ‘php_pdo_mysql.dll’ and ‘php_pdo.dll’ files live (I don’t either).

Problem solved, both of these extensions were listed twice within the php.ini file in completely separate locations. I don’t know how that happened but it is corrected now. Sorry for my stupidity.
