Remove Trailing Slash Using PHP

Question

I'm trying to remove the trailing slash from this link:

href="<?php echo Mage::helper('supermenu')->getLinkbyItem($item); ?>"

In the module there is a field that one uses to enter the link used in the above. I enter the link such as christmas.html but the link gets a trailing slash like this: .../christmas.html/

I found this Remove Trailing Slash From String PHP using rtrimbut don't know how to use it in this context.

Answer 1

Have you tried

echo rtrim(Mage::helper('supermenu')->getLinkbyItem($item), '/');

Answer 2

If I understand your question correctly, you would simply wrap the entire part that is being echoed. It would look like this:

href="<?php echo rtrim(Mage::helper('supermenu')->getLinkbyItem($item)); ?>"
