Sorry, I don't know what GIGO means.

I don't see any difference between single and double quotes on my machine.
Your script echos "SAME". I did try them both before I sent the below
message. I also wasn't using \\\two in my original test. I chose that as a
better illustration. I just switched to \\\pwo (\p isn't anything is it?)
with the same result.

I didn't know about strtr. Thanks. But it doesn't make any difference. My
test script below runs identically. I was running the test interactively--my
php.cgi is version 3.0.7. Just for chuckles, I just ran it through the web
server which is running mod_php 3.0.12. Same results.
