推荐答案

快速解答 - 你的排序两个元素结合在一起，你在他们面前，然后检查他们的答案集已经存在

quick answer - sort your two elements before you combine them, then check if they already exist in the answer set.

$a=array("a","b","c","d");
$b=array("b","c","d","f");

$res = array();
foreach($a as $v1) {
  foreach($b as $v2) {
    $t = array($v1, $v2);
    asort($t);
    $val = implode('', $t);
    if(!in_array($val, $res))
      $res[] = $val;
  }
}
print_r($res);
