php 數組處理

$a:
array (size=16)
0 => string '1' (length=1)
1 => string '3' (length=1)
2 => string '5' (length=1)
3 => string '7' (length=1)
4 => string '10' (length=2)
5 => string '12' (length=2)
6 => string '14' (length=2)
7 => string '16' (length=2)
8 => string '17' (length=2)
9 => string '19' (length=2)
10 => string '21' (length=2)
11 => string '23' (length=2)
12 => string '26' (length=2)
13 => string '28' (length=2)
14 => string '30' (length=2)
15 => string '32' (length=2)

$b:
array (size=16)
0 => string '2' (length=1)
1 => string '4' (length=1)
2 => string '6' (length=1)
3 => string '8' (length=1)
4 => string '9' (length=1)
5 => string '11' (length=2)
6 => string '13' (length=2)
7 => string '15' (length=2)
8 => string '18' (length=2)
9 => string '20' (length=2)
10 => string '22' (length=2)
11 => string '24' (length=2)
12 => string '25' (length=2)
13 => string '27' (length=2)
14 => string '29' (length=2)
15 => string '31' (length=2)

如上數組。我要得到 [16, 1, 13, 4] [14, 3, 15, 2] [12, 5, 9, 8] [10,7, 9 , 8]
[32,17,29,20] [30,19,31,18] [28,21,25,24] [26,23,27,22]

回複討論(解決方案)

看不出有什麼組裝規律

/*規律$a = array(1,3,5,7,  10,12,14,16,  17,19,21,23,  26,28,30,32); a1           a2                    a3        a4$b = array(2,4,6,8,  9,11,13,15,  18,20,22,24,  25,27,29,31); b1           b2                   b3                   b4[16, 1,13, 4][14, 3,15, 2][12, 5, 9, 8][10, 7, 9 ,8]a2 + a1 = b2 + b1 = 17[32,17,29,20][30,19,31,18][28,21,25,24][26,23,27,22]a4 + a3 = b4 + b3 = 49*/t(17);t(49);function t($n){$a = array(1,3,5,7,  10,12,14,16,  17,19,21,23,  26,28,30,32);$b = array(2,4,6,8,  9,11,13,15,  18,20,22,24,  25,27,29,31);$a = array_chunk($a,4);$b = array_chunk($b,4);//15+16 = 31if($n <= 31){$useA = array_slice($a,0,2);$useB = array_slice($b,0,2);}else{$useA = array_slice($a,2,4);$useB = array_slice($b,2,4);}$data = array();arsort($useA[1]);foreach($useA[1] as $v1){foreach($useA[0] as $v2){if($n==$v1+$v2){$tmp = array();$tmp[] = $v1;$tmp[] = $v2;$data['a'][] = $tmp;}}}arsort($useB[1]);foreach($useB[1] as $v1){foreach($useB[0] as $v2){if($n==$v1+$v2){$tmp = array();$tmp[] = $v1;$tmp[] = $v2;$data['b'][] = $tmp;}}}foreach($data['a'] as $k=>$v){echo join(' , ',array_merge($v,$data['b'][$k])).'

是嗎？
[ 12, 5, 9, 8 ]
[ 10, 7, 9, 8 ]
怎麼解釋？

[ 10, 7, 9, 8 ] 應該是[10,7, 11 , 6]
最後結果是兩個數組的組合
a7 a0 b6 b1
a6 a1 b7 b0
a5 a2 b4 b3
a4 a3 b5 b2
a15 a8 b14 b9
a14 a9 b15 b8
a13 a10 b12 b11
a12 a11 b13 b10

[ 12, 5, 9, 8 ]
[ 10, 7, 9, 8 ]
感覺是他寫錯了，不然就沒規律了

好吧，就算他寫錯了
那麼
他要 [ 30, 19, 31, 18 ] 一組
你給 [ 30, 19, 29, 20 ] 一組
也是他寫錯了？

[ 12, 5, 9, 8 ]
[ 10, 7, 9, 8 ]
感覺是他寫錯了，不然就沒規律了

嗯，感覺這樣就不是規律了，有局限性

t(17);t(49);function t($n){$a = array(1,3,5,7,  10,12,14,16,  17,19,21,23,  26,28,30,32);$b = array(2,4,6,8,  9,11,13,15,  18,20,22,24,  25,27,29,31);$a = array_chunk($a,4);$b = array_chunk($b,4);//15+16 = 31if($n <= 31){$useA = array_slice($a,0,2);$useB = array_slice($b,0,2);}else{$useA = array_slice($a,2,4);$useB = array_slice($b,2,4);}$data = array();arsort($useA[1]);foreach($useA[1] as $v1){foreach($useA[0] as $v2){if($n==$v1+$v2){$tmp = array();$tmp[] = $v1;$tmp[] = $v2;$data['a'][] = $tmp;}}}$tmp = array_slice($useB[1],0,2);$useB[1] = array_merge(array_slice($useB[1],2,4),$tmp);foreach($useB[1] as $v1){foreach($useB[0] as $v2){if($n==$v1+$v2){$tmp = array();$tmp[] = $v1;$tmp[] = $v2;$data['b'][] = $tmp;}}}foreach($data['a'] as $k=>$v){echo join(' , ',array_merge($v,$data['b'][$k])).'

我想應該這樣做

$a = array(   1,  3,  5,  7,  10, 12, 14, 16,  17, 19, 21, 23,  26, 28, 30, 32);$b = array(   2,  4,  6,  8,   9, 11, 13, 15,  18, 20, 22, 24,  25, 27, 29, 31);function foo($a) {  $r = array();  foreach(array_chunk($a, 8) as $v) {    $t = array_chunk($v, 4);    $t = array_map(null, array_reverse($t[1]), $t[0]);    $r = array_merge($r, $t);  }  return $r;}$r = foo($a);foreach(foo($b) as $k=>$v) {  $k += $k % 2 ? -1 : 1;  $r[$k] = array_merge($r[$k], $v);}print_r($r);

Array(    [0] => Array        (            [0] => 16            [1] => 1            [2] => 13            [3] => 4        )    [1] => Array        (            [0] => 14            [1] => 3            [2] => 15            [3] => 2        )    [2] => Array        (            [0] => 12            [1] => 5            [2] => 9            [3] => 8        )    [3] => Array        (            [0] => 10            [1] => 7            [2] => 11            [3] => 6        )    [4] => Array        (            [0] => 32            [1] => 17            [2] => 29            [3] => 20        )    [5] => Array        (            [0] => 30            [1] => 19            [2] => 31            [3] => 18        )    [6] => Array        (            [0] => 28            [1] => 21            [2] => 25            [3] => 24        )    [7] => Array        (            [0] => 26            [1] => 23            [2] => 27            [3] => 22        ))

只是調動位置

確實是調換位置，這個有規律些

[12, 5, 9, 8] [10,7, 9 , 8] 是我寫錯，不好意思。宗各位所述已經解決謝謝你們。
