Output items separated by comma apart from last item

[Peter Knight]

Hi

I have a page reference field which are a series of checkboxes in the back end

• Web Design
• Web Development
• Marketing
• Administration

In my template I was previously listing only 1 key skill at a time but now I need to output each checked item separated by a comma

IE

Marketing, Administration

This does work but echoes 

Marketing, Administration,

 foreach
                        ($staff->skills as $item){
                        echo "{$item->title},";}

How would I keep the comma from appearing at the end of the last item?

Thanks

echo $staff->skills->implode(',' 'title');

Or if you need to be more sophisticated (and/or multi-language) something like: https://punic.github.io/#Misc-class

Thanks guys. I actually realized I’d asked this before. Sorry about the duplicate post.

@kongondo's approach is definitely the best for PW, but just for extra info in case you ever need to do this with a standard PHP array, you can simply do:

The ugly way is rarely useful, but I suppose there might be more flexibility depending on your needs.
