求一个递归函数把其显示出来的数据以数据形式return

<code>        function strToLeft($num,$arr){            $i = $arr[$num];            unset($arr[$num]);            array_push($arr,$i);            return $arr;        }        function combine_increase($arr, $start, $result, $count, $NUM, $arr_len)          {            $i = 0;           for ($i = $start; $i = 0; $j--)  {                //if ($j!=0){echo($arr[$result[$j]].",");  }else{echo($arr[$result[$j]]);  }                array_push($tmp, $arr[$result[$j]]);              }              var_dump(strToLeft(rand(0,$NUM-1),$tmp));              echo("<br />");              }              else  { combine_increase($arr, $i + 1, $result, $count - 1, $NUM, $arr_len);  }          }          }                  $arr = array('a1','b2','c3','d4','e5','x1','y1','z1');         $num = 3;           $result[$num]=array();         echo "('a1','b2','c3','d4','e5','x1','y1','z1')";         echo "<br />";         combine_increase($arr, 0, $result, $num, $num, count($arr));</code>

以上代码可生成array(‘a1′,’b2′,’c3′,’d4′,’e5′,’x1′,’y1′,’z1’);这个数组中某三个元素的不同组合，你可以通过laravel（用这个框架写的）或php执行（可能需要小改一下），看一下显示结果，结果应该如下：

(‘a1′,’b2′,’c3′,’d4′,’e5′,’x1′,’y1′,’z1’)
