Wordpress using echo vs return in shortcode function

Question

I just noticed, both echo and return works fine for displaying content from a shortcode function in wordpress.

function foobar_short         


        

Answer 1

I would use:

function foobar_shortcode($atts) {
    return "Foo Bar"; //so does this
}

It is easier when you're doing things like:

$output = '
' . do_shortcode('foobar') . '
';
echo $ouput;
