《PHP應(yīng)用：php實(shí)現(xiàn)每天自動(dòng)變換隨機(jī)問候語(yǔ)的方法》要點(diǎn)：
本文介紹了PHP應(yīng)用：php實(shí)現(xiàn)每天自動(dòng)變換隨機(jī)問候語(yǔ)的方法，希望對(duì)您有用。如果有疑問，可以聯(lián)系我們。
PHP應(yīng)用本文實(shí)例講述了php實(shí)現(xiàn)每天自動(dòng)變換隨機(jī)問候語(yǔ)的辦法.分享給大家供大家參考.具體分析如下：
PHP應(yīng)用這里預(yù)先定義一個(gè)php數(shù)組,里面存放一些隨機(jī)問候語(yǔ),調(diào)用的時(shí)候指定是依照天,月還是年來(lái)自動(dòng)更換問候語(yǔ),如果選擇月,則會(huì)每月更換一條問候語(yǔ)顯示,不用每個(gè)月手動(dòng)更換了,并且這段php代碼比使用JS實(shí)現(xiàn)對(duì)搜索引擎友好
PHP應(yīng)用
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.
*/
PHP應(yīng)用使用范例：
PHP應(yīng)用
// 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);
PHP應(yīng)用希望本文所述對(duì)大家的php程序設(shè)計(jì)有所贊助.
