Question

我的阵列正在咆哮

Array
(
    [1] => Array
        (
            [9] => 6
            [11] => 6
            [12] => 6
            [13] => 6
            [14] => 12
        )
[2] => Array
    (
        [4] => 8
        [8] => 8
        [13] => 13
    )
)

我想要输出如下，有人可以帮助我这样做我希望我总是将阵列分为两部分。

Array
(
    [1] => Array
        (
           [1] => Array( [9] => 6
                         [11] => 6 
                       )
            [2] => Array( [12] => 6
                          [13] => 6
                          [14] => 12
                       )
        )

[2] => Array
        (
             [1] => Array( [4] => 8
                           [8] => 8
                           )
             [2] => Array( [13] => 13
                           )
        )
)

Answer 1

你可以试试这个 -

$new= array_map(function($v) {
    $temp = array_chunk($v, 2); // break in chunks of 2
    $final[]= array_shift($temp); // Take the first chunk out
    $second= array();
    foreach($temp as $t) {
        $second = array_merge($second, $t); // merge the rest chunks
    }
    if(!empty($second)) {
        $final[]= $second;
    }
    return $final;
}, $array);

Fiddle

Answer 2

使用array_chunk和array_slice。

$res = [];
foreach($arr as $k => $v){

  $lastdata = array_slice($v, 2,NULL,true);
  $firstdata = array_chunk($v,2,true);

  $res[$k]['1'] = $firstdata[0];
  $res[$k]['2'] = $lastdata;

}

echo '<pre>'; print_r($res);

<强>输出： -

Array
(
    [1] => Array
        (
            [1] => Array
                (
                    [9] => 6
                    [11] => 6
                )

            [2] => Array
                (
                    [12] => 6
                    [13] => 6
                    [14] => 12
                )

        )

    [2] => Array
        (
            [1] => Array
                (
                    [4] => 8
                    [8] => 8
                )

            [2] => Array
                (
                    [13] => 13
                )

        )

)

希望它会对你有所帮助:)。

Answer 3

    $a=array('1'=>array('9'=>'6','11'=>'6','12'=>'6','13'=>'6','14'=>'12'),'2'=>array('4'=>'8','8'=>'8','13'=>'13'));
    $res = array();
    foreach($a as $k => $v){

      $lastdata = array_slice($v, 2);
      $firstdata = array_chunk($v,2,true);

      $res[$k]['1'] = $firstdata[0];
      $res[$k]['2'] = $lastdata;

    }

echo '<pre>'; print_r($res);

Answer 4

您可以使用array_slice

$res = [];
foreach($arr as $key => $value){

  $res[$key][1] = array_slice($value, 0, 2, true);
  $res[$key][2] = array_slice($value,2, null, true);    
}

var_dump($res);

输出：

Array
(
    [1] => Array
        (
            [1] => Array
                (
                    [9] => 6
                    [11] => 6
                )
            [2] => Array
                (
                    [12] => 6
                    [13] => 6
                    [14] => 12
                )
        )
    [2] => Array
        (
            [1] => Array
                (
                    [4] => 8
                    [8] => 8
                )
            [2] => Array
                (
                    [13] => 13
                )
        )
)

仅限PHP＆gt; 5.2.4：changelog说：length参数的默认值更改为NULL。 NULL长度现在告诉函数使用数组的长度。在此版本之前，NULL长度表示零长度（不会返回任何内容）。
