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 elementreturn $QuotesArray[$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。
