How can I read the data from an external site ?
I mean If I want to search a name in ten sites ?
Is it possible ?

yes you can write a script to do that.

A good example is.
http://www.dogpile.com/


It searches on yahoo google msn

Or you can use site search and program it to get results from 10 of your websites.

http://www.google.com/sitesearch/

This is the wrong for for the question??? dont you think ..

IT is possible yes, but you should note that Google WILL block the ip unless you use the google API and all that etc and get the key blah blah blah.

but for simply grabbing a external page file_get_contents(URL) grabs the page and puts it into a string where you can them manipulate it...

be more precise and we can help further.
