Can a PHP script, when given the correct "starting" page,

but the script is the "browser" instead of me. I'm thinking this
can be called by a cron job.
For simulating a web browser, Snoopy is good:

"Snoopy is a PHP class that simulates a web browser."
For parsing the HTML sent to the "browser," Tidy can convert
invalid HTML to valid XML, and PHP's built-in DOM functions can
parse XML:
http://tidy.sourceforge.net/
http://php.net/dom
http://php.net/domxml
Add in scheduling with cron and you've just created a search engine.
Peace,
