if [current time] is between 7AM and 5PM, do this, else do this

so my dad wants me to make his website so that if someone goes to it during daylight hours, it shows a daytime photo of the building. At night, it shows the night photo. I figure this can be done with a simple "if" statement, but I don't know how to work with PHP time formats!

date('G') will give you the current hour in 24 hour format.  so..

[code=php:0]$hour = date('G');
if ($hour >= 7 && $hour < 17) {
  # daytime
} else {
  # nighttime
}[/code]
