Hi
Is it possible to use php to display different text each day for my website.

Yes it is. Using the date() function you can find which day of the week it is and base your content on that.

As stymiee said, you can do it. For example something like this:

<?php

	$d = date('w');

	$maxim[] = 'sunday';
	$maxim[] = 'monday';
	$maxim[] = 'tuesday';
	$maxim[] = 'wednesday';
	$maxim[] = 'thursday';
	$maxim[] = 'friday';
	$maxim[] = 'saturday';

	echo $maxim[$d];

?>

Just replace 'sunday, monday...' with your text.
Bye :)
