php实现每天自动变换随机问候语的方法

本文实例讲述了php实现每天自动变换随机问候语的方法。分享给大家供大家参考。具体分析如下：

这里预先定义一个php数组，里面存放一些随机问候语，调用的时候指定是按照天，月还是年来自动更换问候语，如果选择月，则会每月更换一条问候语显示，不用每个月手动更换了，并且这段php代码比使用JS实现对搜索引擎友好

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.*/

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);

希望本文所述对大家的php程序设计有所帮助。
