PHP error log problem 'Unable to load dynamic library'

My PHP error logs are filling up extremely rapidly with the following line:

[28-Apr-2011 13:03:00] PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20060613/' - /usr/local/lib/php/extensions/no-debug-non-zts-20060613/: cannot read file data: Is a directory in Unknown on line 0

I've googled the issue and found several results, but all involving something开发者_如何学JAVA after the last / where this error appears to be something to do with the path itself.

The site(s) are running on cPanel/WHM on CentOS.

You will need to check your php.ini. One of the entries there does not specify a correct filename, but probably something like this:

extension = .

; or the raw pathname as shown in your error.log
extension = /usr/local/lib/php/extensions/no-debug-non-zts-20060613/

That's why the error says Is a directory.

The in Unknown on line 0 refers to your php.ini (it does not have a __FILE__ or __LINE__ number, so leads to that mysterious location hint.)
