Can PHP automatically remove text

[phpbegin]

I have some text, and I want it to appear and disappear on a certain date? For example, if I had this on a website -

"By December 1, 2005, email me your ideas"

Can PHP remove "By December 1, 2005, email me your ideas" after the date without manually taking it off myself? If so, where can I find code examples?

if(time() <= strtotime("2005/12/01"))
{
echo "By December 1, 2005, email me your ideas.";
}

[phpbegin]

Thank you
