error_log file

[kb0000]

I am using Cpanel.
When ever any user opens any .php page on my website (whether the page contains some code or is empty) there is some error lines logged in the error_log file.
Following is the error:

[06-May-2008 05:41:39] PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20060613/php_domxml.dll' - /usr/local/lib/php/extensions/no-debug-non-zts-20060613/php_domxml.dll: cannot open shared object file: No such file or directory in Unknown on line 0

I have asked the hosting provider to check if the associated things are enabled or not. They said they are enabled.
What should I do to prevent them.

DLLs are for Windows, SO are for linux. Change the extension from ".dll" to ".so".

Note that these changes will most likely need to be made in a php.ini file somewhere, not in your actual script(s).
