製作多個陣列的每個組合，而不必在每個陣列中重複項目

Question

讓我先說這一點，我並不是想要獲得所有組合。

我試圖讓每個隊伍有6名球員的每一個組合，而沒有每個球員與另一名球員在一個新的球隊中。 例如

$team1 = "John, Joey, Steve, Lee"; 
$team2 = "Tom, Alex, Billy"; 
$team3 = "Clint"; 
$team4 = "Alan, Jerry"; 
... 
$team10 = "James, Corey, Paul, Benny"; 

John和喬伊不能在未來的組合;湯姆和比利不能在將來組合在一起。但我試圖從10支球隊的每一支中獲得每個球員的組合。 我有一個聯合陣列的所有十個球隊$團隊

我一直在嘗試使用這個功能，但我認爲我在錯誤的軌道上。

function combinations($arrays, $i = 0) { 
    if (!isset($arrays[$i])) { 
     return array(); 
    } 
    if ($i == count($arrays) - 1) { 
     return $arrays[$i]; 
    } 

    // get combinations from subsequent arrays 
    $tmp = combinations($arrays, $i + 1); 

    $result = array(); 

    // concat each array from tmp with each element from $arrays[$i] 
    foreach ($arrays[$i] as $v) { 
     foreach ($tmp as $t) { 
      $result[] = is_array($t) ? 
       array_merge(array($v), $t) : 
       array($v, $t); 
     } 
    } 

    return $result; 
} 

print_r(
    combinations(
     array(
      $team[1], 
      $team[2], 
      $team[3], 
      $team[4], 
      $team[5], 
      $team[6], 
      $team[7], 
      $team[8], 
      $team[9], 
      $team[10] 
     ) 
    ) 
);
