Php implements the method of automatically changing random greetings every day

This article mainly introduces php's method of automatically changing random greetings every day, involving time and array related operations, for more information, see the following example. Share it with you for your reference. The specific analysis is as follows:

A php array is pre-defined here, which contains some random greetings. you can specify whether the greetings are automatically changed by day, month, or year when calling. if you select month, a new greeting is displayed every month, you don't need to change it manually every month, and this php code is more friendly to search engines than using JS.

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];}/*** --> See the example section below for a**   detailed instruction.*/

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);

I hope this article will help you with php programming.
