run code depending on the time of day
提问by user983248
I need to echo some code or message on a page depending on the hour of the day. Just like a welcome message, "good evening", or "good afternoon"
我需要根据一天中的小时在页面上回显一些代码或消息。就像一条欢迎信息，“晚上好”或“下午好”
I don't know hot to group certain hours and assign a message to each group like
我不知道热点分组某些时间并向每个组分配一条消息，例如
from 1:00:00 pm to 4:00:00pm = "good afternoon" and from 4:00:01 to 8:00:00 = "good evening"
从 1:00:00 pm 到 4:00:00pm =“下午好”和从 4:00:01 到 8:00:00 =“晚上好”
so far I have :
到目前为止我有：
<?php
date_default_timezone_set('Ireland/Dublin');
$date = date('h:i:s A', time());
if ($date < 05:00:00 AM){
echo 'good morning';
}
?>
But I don't know how to pass the hours range an the messages.
但我不知道如何传递消息的时间范围。

<?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";
}
?>

I thought this thread could use a nice one-liner:
我认为这个线程可以使用一个很好的单线：
$hour = date('H');
$dayTerm = ($hour > 17) ? "Evening" : (($hour > 12) ? "Afternoon" : "Morning");
echo "Good " . $dayTerm;
If you check the highest hour first (evening), you can eliminate the range checks completely, and make a nice, more compact conditional statement.
如果您首先检查最高小时（晚上），则可以完全消除范围检查，并制作一个漂亮的、更紧凑的条件语句。

$hour = date('H', time());
if( $hour > 6 && $hour <= 11) {
echo "Good Morning";
}
else if($hour > 11 && $hour <= 16) {
echo "Good Afternoon";
}
else if($hour > 16 && $hour <= 23) {
echo "Good Evening";
}
else {
echo "Why aren't you asleep? Are you programming?";
}
...should get you started (timezone insensitive).
...应该让你开始（时区不敏感）。
回答by maxHymanie
$dt = new DateTime();
$hour = $dt->format('H');
now check this $hourin your morning , afternoon , evening or night range and accordingly give the message
现在$hour在你的早上、下午、晚上或夜间范围内检查这个，并相应地给出信息

date_default_timezone_set('Asia/Dhaka');
$time=date('Hi');
if (($time >= "0600") && ($time <= "1200")) {
echo "Good Morning";
}
elseif (($time >= "1201") && ($time <= "1600")) {
echo "Good Afternoon";
