這篇文章主要介紹了php實現每天自動變換隨機問候語的方法,涉及時間與數組的相關操作技巧,需要的朋友可以參考下
本文實例講述了php實現每天自動變換隨機問候語的方法。分享給大家供大家參考。具體分析如下:
這里預先定義一個php數組,里面存放一些隨機問候語,調用的時候指定是按照天,月還是年來自動更換問候語,如果選擇月,則會每月更換一條問候語顯示,不用每個月手動更換了,并且這段php代碼比使用JS實現對搜索引擎友好
- 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);
希望本文所述對大家的php程序設計有所幫助。
