Well, I think it matches this: http/1\\2 3 $

I can't imagine that is what you want! Can you post your egregi regex?

My server does not have cURL

My server does not have cURL installed, this is just part of an HTTP class that does the same job as cURL. because eregi has been deprecated I had to convert it to preg_match.
Why doesnt it look right?

You need to escape the / but

You need to escape the / but if you change the delimiter to a hash, then you won't need to:

#^http/[0-9]+\\.[0-9]+[ \t]+([0-9]+)[ \t]*(.*)\$#

That regex doesn't look right anyway. What are you trying to match?
