LIST explode(STRING str[, STRING sep[, INTEGER want-blanks]])
This function breaks string into a list of strings, using the string sep as the delimiter. If sep is unspecified it uses spaces as the delimiter. If want-blanks is specified and is true explode() will include zero-length strings in the final list, otherwise it will not. The function split() is similar, but uses a regular expression as the delimiter. Examples:
explode(" foo bar baz")
=> ["foo", "bar", "baz"]
explode("foo:bar::baz", ":")
=> ["foo", "bar", "baz"]
explode("foo:bar::baz", ":", 1)
=> ["foo", "bar", "", "baz"]
