//使用范例：
// 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
