Checking if a date is within 7 days of the current time
提问by David G
So I have a php function which interacts with a database and pulls data out. However I have a date stamp (in this case an upload date). I want to make it so that if something has been uploaded within the last 7 days, it posts that to users to make them aware of it being 'new'.
所以我有一个与数据库交互并提取数据的 php 函数。但是我有一个日期戳（在这种情况下是上传日期）。我想这样做，如果在过去 7 天内上传了某些内容，它会将其发布给用户，让他们知道它是“新的”。
So far I have this:
到目前为止，我有这个：
if( strtotime($rows['Date']) > strtotime('now') ) {
echo '<div class="l-new"><a href="#"><!-- --></a></div>';
}
The $rows thing is taken care of and works from some other code above this line. But this is the line I am concerned with.
$rows 事情由该行上方的其他一些代码处理和工作。但这是我关心的线。
I want to say "if the date in the database is older than the current time, and is less than 7 days old, do the following { //echo the stuff about it being new }
我想说“如果数据库中的日期比当前时间早，并且不到 7 天，请执行以下操作 { //echo the stuff about it is new }
Problem is, how do I phrase that if statement to make it within 7 days? Absolutely cannot think of how unfortunately. I'm sure it is quite simple! Thank you
问题是，如何在 7 天内表达 if 语句？绝对想不到有多不幸。我相信这很简单！谢谢

if( strtotime($rows['Date']) > strtotime('-7 day') ) {
echo '<div class="l-new"><a href="#"><!-- --></a></div>';
}
The strtotime('-7 day')part returns the time 7 days ago.
该strtotime('-7 day')部分返回时间为7天前。
