Where do I put substr?

Question

I have this code that I need to add substr to, to limit the description output to 100 characters:

description=<?=nl2br(strip_tags($v['listing_description']));?>

Where and how do I add substr to this line?

I have tried a few different methods, with no success.

Answer 1

The substr goes between nl2br and strip_tags :

description=<?=nl2br(substr(strip_tags($v['listing_description']), 0, 100));?>

The reason for this is because you first want to strip_tags (the inner-most parentheses), then substr to 100 characters, then convert new-lines to <br> s.
