php大于一定时间 [英] php greater than certain time
问题描述
我正在尝试制作一个简单的函数来根据一天中的时间输出 2 行不同的文本.我希望它在下午 4 点之后说 - 次日交货将在次日处理.
I am trying to make a simple function to output 2 different lines of text depending on the time of the day. I want it to say after 4pm - Next day delivery will be processed the following day.
到目前为止我已经写了这个:
I have wrote this so far:
<?php
$currentTime = time() + 3600;
echo date('H:i',$currentTime);
?>
但是由于date函数返回一个字符串,我不确定如何使用IF语句来检查时间是否大于16:00.
However as the date function returns a string, I am unsure of how to use an IF statement to check whether the time is greater than 16:00.
推荐答案
应该做的
if (((int) date('H', $currentTime)) >= 16) {
// .. do something
}
因为 PHP 是弱类型的,所以可以省略 (int)
-casting.
Because PHP is weak-typed you can omit the (int)
-casting.
作为旁注:如果你命名一个变量 $currentTime
,你不应该向它添加 1 小时,因为它不再是当前时间,而是未来一小时的时间;) 在所有
As a sidenote: If you name a variable $currentTime
, you shouldn't add 1 hour to it, because then its not the current time anymore, but a time one hour in the future ;) At all
if (date('H') >= 16) { /* .. */ }
