php 数组处理

$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)

  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)

如上数组。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]

回复讨论(解决方案)

看不出有什么组装规律

/*规律$a = array(1,3,5,7,  10,12,14,16,  17,19,21,23,  26,28,30,32);			 a1	           a2	                    a3	        a4$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 = 31	if($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])).'

是吗？
[ 12, 5, 9, 8 ]
[ 10, 7, 9, 8 ]
怎么解释？

[ 10, 7, 9, 8 ] 应该是[10,7, 11 , 6]
最后结果是两个数组的组合
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 ]
感觉是他写错了，不然就没规律了

好吧，就算他写错了
那么
他要 [ 30, 19, 31, 18 ] 一组
你给 [ 30, 19, 29, 20 ] 一组
也是他写错了？

[ 12, 5, 9, 8 ]
[ 10, 7, 9, 8 ]
感觉是他写错了，不然就没规律了

嗯，感觉这样就不是规律了，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 = 31	if($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])).'

我想应该这样做

$a = array(   1,  3,  5,  7,  10, 12, 14, 16,  17, 19, 21, 23,  26, 28, 30, 32);$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        ))

确实是调换位置，这个有规律些

[12,  5,  9,  8]   [10,7, 9 ,     8] 是我写错，不好意思。宗各位所述已经解决谢谢你们。
