如何检查date（）函数是否减一？

Question

Is it possible to check if the date ("j-1 F-1")???

I'm a noob so some script would help! Postdate is in a format like: 14 October.

if ($postdate == date("j F")) {$postdate = "today";} THIS WORKS...

But I need to check the $postdate for the "yesterday" value as well!

Q: How to check for yesterday? that is, date()-1 somehow.

Thanks again

Answer 1

date('j F', strtotime('-1 day'));

Will retrieve the "yesterday" timestamp. So :

if ($postdate == date('j F', strtotime('-1 day'))) {$postdate = "yesterday";}
