WordPress, How Many Days Old is the Post

Over on Performancing.com Andy, says the money is in the archives, stupid. Nick talks about Monetizing your Blog, by showing different levels of advertising based on how old post is and whether someone is logged in or not. Now Andy’s doing a blog monetization makeover, and time sensitive ads came up again. Since I’ve got the hood open on this WordPress install I figured I would work up some code to figure out how old a post is.

$postdate = str_replace("-", " ",substr($post->post_date, 0,10));
$postd = explode(" ", $postdate);
$ageunix = (( time() - mktime('','','', $postd[1], $postd[2], $postd[0])));
$days_old = floor($ageunix/(24*60*60));

Basically what I’m doing is getting time and date of the post. I then isolate the just date and remove out “-” characters. I explode it into an array, convert them to unixtime, and do the subtraction. Then convert it back from UNIX time to days old expressed as an integer value (my high school math teacher Sister Miriam would be proud).
