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,php自动变换的随机问候语的实现方法,感兴趣的小伙伴,下面一起跟随脚本之家 jb51.cc的小编来看看吧。 经测试代码如下:
/**
* 自动更换问候语
*
* @param
* @arrange (512.笔记) jb51.cc
**/
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);
// --> returns "PHP is cool." on September 25,2007
