Today I was building a list of links on a WordPress site using wp_list_bookmarks.  I wanted to create a comma-separated list such that each link title would have a link after it.  No problem.

Except….the final link also has a comma after it.  The result looks like this:

link 1, link 2, link 3, link 4,

I want it to look like this (with no trailing comma):

link 1, link 2, link 3, link 4

To accomplish this, I used a few php functions as follows:

 '',
		'after'   => ', ',
		'echo'    => '0';
?>

  

Notice that in the $args array, I add a comma after each link. Then in the final echo line, I remove the trailing comma.

Pretty cool, eh!

Do you know of a better way to do this?

SOURCE: I found this solution on the WordPress.org forums, but I lost the link. Sorry!
