设置基于用户的时间问候（早上好，下午好...）

Question

任何人都可以推断如何实现基于用户的时间设定一个基本的“晚上好”或“早上好”？

也许PHP将获取服务器的时间，但我期待与他们认为一天中的时间基于时间的合适的问候迎接站点访问者。

例如为：早上好，晚上好，下午好。

Answer 1

它的基础上的日期对象的.getHours()。使用JavaScript的Date对象将自动使用用户的本地时间，而不是服务器时间：

var now = new Date(); 
alert(now.getHours()); 

几个条件检查，而你在企业里。例如，下面是一个非常简单和容易理解的例子：“早上好阳光”

var now = new Date(); 
var hrs = now.getHours(); 
var msg = ""; 

if (hrs > 0) msg = "Mornin' Sunshine!"; // REALLY early 
if (hrs > 6) msg = "Good morning";  // After 6am 
if (hrs > 12) msg = "Good afternoon"; // After 12pm 
if (hrs > 17) msg = "Good evening";  // After 5pm 
if (hrs > 22) msg = "Go to bed!";  // After 10pm 

alert(msg); 

这是目前上午2时56分在这里，所以我看当我运行这个。您可以使用此在线演示测试你自己的本地时间：http://jsbin.com/aguyo3/edit

<?php 
// I'm India so my timezone is Asia/Calcutta 
date_default_timezone_set('Asia/Calcutta'); 

// 24-hour format of an hour without leading zeros (0 through 23) 
$Hour = date('G'); 

if ($Hour >= 5 && $Hour <= 11) { 
    echo "Good Morning"; 
} else if ($Hour >= 12 && $Hour <= 18) { 
    echo "Good Afternoon"; 
} else if ($Hour >= 19 || $Hour <= 4) { 
    echo "Good Evening"; 
} 
?> 

有关日期更多信息，请function.date。我希望这将有所帮助。

REPEAT

 IF time is after 12pm THEN 

        OUTPUT ‘Good Afternoon, what can I get you?’ 

     IF time is before 12pm THEN 

        OUTPUT ‘Good morning, what can I get you?’ 

     INPUT user inputs what they would like 

     STORE the user’s input in the answer variable 

     IF answer = ‘Coffee’ THEN 

       OUTPUT ‘Would you like milk or sugar with that? 

     ELSE 

        OUTPUT ‘No I am sorry, we only serve coffee!’ 

UNTIL答案= '咖啡'

​​

STORE用户在应答变量输入

IF答案= '否' THEN

 OUTPUT ‘No problem, I will just get that for you!’ 

ELSE

IF答案=“是” THEN

 OUTPUT ‘No problem, I will take care of that for you!’ 

     Make coffee for customer

<?php 
    /* This sets the $time variable to the current hour in the 24 hour clock format */ 
    $time = date("H"); 
    /* Set the $timezone variable to become the current timezone */ 
    $timezone = date("e"); 
    /* If the time is less than 1200 hours, show good morning */ 
    if ($time < "12") { 
     echo "Good morning"; 
    } else 
    /* If the time is grater than or equal to 1200 hours, but less than 1700 hours, so good afternoon */ 
    if ($time >= "12" && $time < "17") { 
     echo "Good afternoon"; 
    } else 
    /* Should the time be between or equal to 1700 and 1900 hours, show good evening */ 
    if ($time >= "17" && $time < "19") { 
     echo "Good evening"; 
    } else 
    /* Finally, show good night if the time is greater than or equal to 1900 hours */ 
    if ($time >= "19") { 
     echo "Good night"; 
    } 
    ?>
