Use preg_split to split a string on "," and " and "

Question

I now split the sting op , only like this:

$a_string = preg_split('/[,]/', $sting);

I also want to split the sting on " and " but i can't find the right regex.

Answer 1

preg_split('/(?:,| and )/', $sting);

Answer 2

You can also just do:

$arr = preg_split('/,| and /', $str);

as | (alteration) has a very low precedence and binds last.
