What does stdout in display_errors in phpinfo() mean?

php, security

Solution

stdout is the output stream that is used for normal output. echo "hello worl"; outputs to stdout. You can also log to file, or output to stderr. I don't think stderr is useful in the web context, but I could be wrong.

PHP Manual: `php://` — Accessing various I/O streams - (PHP Wrappers)

Problem

I have 'stdout' under display_errors in my phpinfo. What does it mean? Where can I find the documentation about it? I could not find one in http://php.net/ I read here telling that it should be off for the security reasons. Thanks in advance.
