Functions For Php Bot

[mwichmann4]

I am wanting to learn how to create a script that can spider a given url. Could someone give me some php 4 functions to study that will help me do that. Thanks

first you might need the file() function.

$page = file("http://www.website.com");

Then you might try using some string functions... strpos, to find the string being searched for... also maybe substr(),

Thanks for that one. Will the parse the html in the link that I give. I mean how does it know to grab the html and stuff?
