getting array from textarea?

[villan]

I'm trying to grab data entered into a textarea tag and put it into an array in php. Then process the textarea data line by line. I have the latter part worked out, just need to figure out how to put it into an array.

explode() maybe?

<textarea name="string"></textarea>

$data = explode("\n", $_POST['string']);

This would seperate all the data by line and pop it into an array called $data.
