Get only days ago the node was posted - Drupal 7

Question

How can I get only days ago the node was posted?

E.g. If node post date is yesterday only print "1" or node post date is 1 month and 1 week ago only print "37"

I am trying to solve this by using following snippet but failed

<?php echo 'Posted: ',format_interval(time()-$node->created); ?>

Answer 1

format_interval() function formats a time interval with the requested granularity.

For example if current Unix time is 1427868018 and node created time is 1366045256:

• format_interval((time() - $node->created) , 1)) returns "1 year",
• format_interval((time() - $node->created) , 2)) returns "1 year 11 months",
• format_interval((time() - $node->created) , 3)) returns "1 year 11 months 2 weeks",
• format_interval((time() - $node->created) , 4)) returns "1 year 11 months 2 weeks 6 days".

If you want to display only days, you can use following code:

$intervalSeconds = time() - $node->created;
$intervalDays = floor($intervalSeconds / 86400);

print $intervalDays;

if ($intervalDays == 1) {
    print ' day';
} else {
    print ' days';
}

It will return "715 days".
