If I use the backtick operator, like:

 $output = `command goes here`;

and if the program 'command' returns its output to stderr and not stdout, then it's not easy to get the output.

Right now, it can be solved by adding:

 2> /tmp/file/here

and then reading the file in the script, but that's not a good solution.

What you want can be probably be achieved with:

$output = `command 2>&1`;

RE: edink@php.net

Yes, but that's platform specific solution, so I think it would be better to make PHP return the output to stderr too.

For example, that doesn't work on Win9x.

It works fine in the windows versions I've tried it on. And current PHP versions don't work with Win9x anyway -> bogus.
