Timer Script effect

[ndiniz]

I was thinking: I have a countdown timer on my website for a trip to Walt Disney world, and I'd like to create a block of PHP code that will make the timer disappear from the screen anywhere from a minute to 10 seconds before the timer expires, and then I'd like to use that random amount of time for a delay, and after that delay, I'd like to create some text that replaces the timer saying "Time's Up!" Is this possible?

not with php as its client side, you need something like javascript

Thanks for the help!
