I get this error in my logs a lot:
Deprecated function: Methods with the same name as their class will not be constructors in a future version of PHP; views_many_to_one_helper has a deprecated constructor in require_once() (line 127 of C:\...\sites\all\modules\contrib\ctools\ctools.module).
This is really not important to me and I don't want it filling up watchdog. Is there any easy way to tell Watchdog to not log these errors? Where can I change which errors get logged by watchdog?
