I don't really need it to log into a file, but I wanted to prevent it
from echoing to the screen.
So I guess there's no way to prevent from error_log() (using defaults)
to echo to the screen (STDOUT).
error_reporting() affects on errors produced by PHP itself. I tried to
set it to 0 before the call, but it didn't help.
set_error_handler() affects on trigger_error() and not on error_log().
It seems that the extern lib I use should use trigger_error() (or
user_error()) function instead, which is the traditional way to report
user-defined errors.
Thanks for your help all...
