Quick Pattern Help

[Shawazi]

This is a continuation of what I was working on before but this part is simple. I'm just bad with patterns.
I need

if (ereg("blah","$server_[HTTP_USER_AGENT]"))

where blah says the variable must have 'MSIE 5.0' but can have any characters before or after that.

get_browser() isn't working so I e-mailed my server to see if they have the right setting.

If I use this code

echo $HTTP_USER_AGENT['version'];

I just get M
what does that mean?
