Chop up a variable

[AmazingAnt]

I've got a variable that has a few different pieces of information, and each piece is seperated by a specific symbol. It's kinda like a csv file, except that it's using dashes "-" instead of commas "," to seperate each piece of data. No, the information isn't in a file, just the variable. How can I split the variable apart at each dash, and send it into an array?

$someArray = explode("-",$someVariable);

Thanks!
