PHP redirect based on IP addresses -

I need to show the IP address of the specific category and the content for others that I want to redirect.

I got this code to check the IP address:

    
 The code works, it actually redirects to Yahoo, but I need to show the content instead of redirection. And redirect all other IP addresses.  
 How do I modify the script?   
 
 
 Your approach is weird that those  in_array  matches against wild cards just do not seem to be anything That's all IP preggers patterns.
