checking for html 404 error

[kmcvay]

I have a page that sends people to another website directing them to a sub-page. The problem is the addresses of these sub-pages change as that site updates or makes changes. So I'd like to check prior to sending them, that the page still exists. If it doesn't exist, I can send them to the other site's homepage. How can I code this in php so that they aren't directed to an empty page (404 error)?

You can use the [man]cURL[/man] functions, specifying via [man]curl_setopt/man to only receive the response headers, then check them for the response code.

Actually, I found an example which uses get_headers($url, 1) and then uses an if statement to check for 404 errors. I just have to work it into my control file now.

Thanks anyway.
