RSS crawl for TV Studio Set

[ssnelgrove]

So a little background I have to create a RSS feed for a crawl for a monitor wall above out studios news desk that only accepts the description field so I have made a page that takes another RSS feed and only displays the description field and adds some spaces then a pipe with a few more spaces and makes it all CAPS

 

Making it look like this

CRAWL ITEM 01    |    CRAWL ITEM 02    |    CRAWL ITEM 03    |

 

The problem is I need the get rid of the ending pipe

 

Making it look like this

CRAWL ITEM 01    |    CRAWL ITEM 02    |    CRAWL ITEM 03

 

This is what I have so far If anyone can show me how to get rid of the ending pipe would be great. I have read about the implode function but don’t know how to implement it I and very novice with php, most of the code I got off another forum

 

And yes a lot of things are commented out incase I need then in the future

 

Thx

What are you trying to do with implode? 

 

Did you read up on substr in the manual?  You wanted to remove the last pipe symbol which is the last character of your string, no?  The substr function is made just for something like that.
