Alright I've been working on this for a few hours now and need some help. Basically what I have is a string that looks like this:

Ex. "I like [[football]], [[basketball]], and going to the [[park]]."

Now I want to grab the words enclosed with the brackets and put them in an array. I'm completely lost here. I thought about using preg_match but don't know enough about how to use it. If you could make me a simple function that would be great!

Yep, regular expressions would be the easiest way to do that. I'd need to see another example or two of input to help you write the expression though.

Just pretty much what I have above. Like if you could write a function like this I'd really appreciate it:

function keyterms($string) {
   /* Use the regular expresstion here to grab the words */
    $keyterms = array(PUT THE WORDS THAT ARE PULLED FROM THE STRING HERE e.g. "basketball","baseball","park")
    return $keyterms;
}

The words will be enclosed with what I had above "[[", "]]".
