For example, I get: adamh@swiftdesk7:/tmp$ php -i | egrep '(display_errors|error_log)' display_errors => STDOUT => STDOUT error_log => no value => no value And as you'd expect, errors are output to stdout. ------------------------------------------------------------------------ [2013-05-20 14:13:49] weirdan at gmail dot com Those folders contain vanilla PHP code, with NO Debian patches applied. ------------------------------------------------------------------------ [2013-05-20 14:08:21] weirdan at gmail dot com Description: ------------ Error messages in CLI should go to STDERR.
