get page height

[xanderman]

i would like a "go to top" type of link on my page to appear only if there is enough text on the page to warrant the need for such a link. since the page content will be constantly updated i was wondering if there was any way to do this through php so that if a vertical scrollbar appeared on the page, then the 'go to top' link would be displayed. is this possible?

Nope. not with php. There's javascript to do it, but not php.

thanks for your reply, i guess i will go look into the javascript way.
