PHP explode the string, but treat words in quotes as a single word

This would have been much easier with str_getcsv().

$test="Lorem ipsum "dolor sit amet" consectetur "adipiscing elit" dolor";
var_dump(str_getcsv($test, ' '));

Gives you

array(6) {
  [0]=>
  string(5) "Lorem"
  [1]=>
  string(5) "ipsum"
  [2]=>
  string(14) "dolor sit amet"
  [3]=>
  string(11) "consectetur"
  [4]=>
  string(15) "adipiscing elit"
  [5]=>
  string(5) "dolor"
}
