PHP Filtering some html...

[The Geek]

It would be possible (if I understand you right) - however it would be a nightmare to do.

Based on my understanding, you would need a script to:
open a URL and get its contents.
Loop through the lines and strip out the headers and build 1 big string.
Search and replace whatever you are trying to replace (which isn't as easy as it sounds)
Then push it down to whoever asked for it.

That would take at least 3 times longer then rendering a page to them and take twice as much bandwidth.

I don't mean to be all negative Nancy and stuff. Just trying to point out the overheads of what you are trying to accomplish.

Heres a link for the fopen function that would fetch the page for you -> http://uk.php.net/manual/en/function.fopen.php
