How do I chop the end off of these phrases?

[Jeffro]

I need a php fix that says... No matter what the phrase (because it will always be different), delete the last 3 dashes and the last 3 words.

 

This-is-an-example-sentence-right-here 

 

would output:

 

This-is-an-example

 

Possible.. or too tricky? 

Thanks!

You don't need regex for this. You can just use explode:

 

$str = 'This-is-an-example-sentence-right-here';
echo implode('-', explode('-', $str, -3));

 

Note: This requires PHP 5.1.0 (when support for a negative limit parameter was added).

That could not have worked any better.  I expected a much longer solution.  THANK YOU!!!
