获得比修改的最后日期早三分钟的东西

Question

I have the following:

$isOlderThenThreeMinutes = $this->getDateModified() <= strtotime('-3 minutes');

pretty basic. How ever I was logging this the whole time and I get 1 every time this check returns. So I thought ok what happens if I wait 15 minutes and check it again, still 1 thus its never truly older then three minutes.

Whats wrong with this? getDateModified() returns YYYY-MM-DD HH:MM:SS

How do I say: if older then 3 minutes return true, else return false? it returns one every time, even if its 2 seconds old or 30 minutes old ....

Answer 1

You need to convert $this->getDateModified() to a Unix Timestamp since that is what strtotime(-3 minutes) returns.

isOlderThenThreeMinutes = strtotime($this->getDateModified()) <= strtotime('-3 minutes');
