Daily changing random quotes
This example shows how to display a random quote that changes only daily, monthly or just every year.
<br/>
This is much better than quotes that change on every page load because it is search engine friendly and does not confuse the visitors.

function RandomQuoteByInterval($TimeBase, $QuotesArray){
// Make sure it is a integer
$TimeBase = intval($TimeBase);
// How many items are in the array?
$ItemCount = count($QuotesArray);
// By using the modulus operator we get a pseudo
// random index position that is between zero and the
// maximal value (ItemCount)
$RandomIndexPos = ($TimeBase % $ItemCount);
// Now return the random array element
return $QuotesArray[$RandomIndexPos];
}
//Example:
// Use the day of the year to get a daily changing
// quote changing (z = 0 till 365)
$DayOfTheYear = date('z');
// You could also use:
// --> date('m'); // Quote changes every month
// --> date('h'); // Quote changes every hour
// --> date('i'); // Quote changes every minute
// Example array with some random quotes
$RandomQuotes = array(
'No animals were harmed in the making of this snippet.',
'Nice snippets',
'The modulus operator rocks!',
'PHP is cool.'
);
print RandomQuoteByInterval($DayOfTheYear, $RandomQuotes);
// --> returns "PHP is cool." on September 25, 2007
