将php中的一个数组对象分离为两个新的基于php的数组对象偶数索引和奇数索引

Question

我在php:上有一个这样的数组

echo "<pre>";
print_r($header_item);

结果是：

Array
(
  [0] => stdClass Object
   (
     [NO_INSPECTION] => 47
     [ID_CONDITION] => 1
     [NAMA_CONDITION] => DIRTY
   )
  [1] => stdClass Object
   (
     [NO_INSPECTION] => 47
     [ID_CONDITION] => 2
     [NAMA_CONDITION] => DAMAGE
    )
  [2] => stdClass Object
   (
    [NO_INSPECTION] => 
    [ID_CONDITION] => 
    [NAMA_CONDITION] => CLEAN
   )
  [3] => stdClass Object
   (
    [NO_INSPECTION] => 
    [ID_CONDITION] => 
    [NAMA_CONDITION] => OFF HIRE
 )
)

我有这样的情况，这个数组将被分离为两个新的数组对象，基于偶数和赔率索引。所以我这样写：

<?php
    $odd = array();
    $even = array();
    $breakrow = 0;
       foreach ($header_item as $v) {
             if ($breakrow % 2 == 0) {
                array_push($even, $v->NO_INSPECTION);
                array_push($even, $v->ID_CONDITION);
                array_push($even, $v->NAMA_CONDITION);
             } else {
                array_push($odd, $v->NO_INSPECTION);
                array_push($odd, $v->ID_CONDITION);
                array_push($odd, $v->NAMA_CONDITION);
             }
        $breakrow++;
       }
  ?>

但我得到了这样的新阵列：

echo "<pre>";
print_r($even);
echo "<br>";
echo "<pre>";
print_r($odd);
Array
(
 [0] => 47
 [1] => 1
 [2] => DIRTY
 [3] => 
 [4] => 
 [5] => CLEAN
)
Array
(
 [0] => 47
 [1] => 2
 [2] => DAMAGE
 [3] => 
 [4] => 
 [5] => OFF HIRE
)

我怎么能这样做：

  Array
  (
    [0] => stdClass Object
      (
       [NO_INSPECTION] => 47
       [ID_CONDITION] => 1
       [NAMA_CONDITION] => DIRTY
      )
    [1] => stdClass Object
      (
       [NO_INSPECTION] => 
       [ID_CONDITION] => 
       [NAMA_CONDITION] => CLEAN
      )

和：

  Array
  (
    [0] => stdClass Object
      (
       [NO_INSPECTION] => 47
       [ID_CONDITION] => 2
       [NAMA_CONDITION] => DAMAGE
      )
    [1] => stdClass Object
      (
       [NO_INSPECTION] => 
       [ID_CONDITION] => 
       [NAMA_CONDITION] => OFF HIRE
      )

Answer 1

您可以使用array_walk和一个简单的密钥奇偶测试来实现这一点。

$header_item = [
    0   =>  'zero',
    1   =>  'one',
    2   =>  'two',
    3   =>  'three',
    4   =>  'four',
    5   =>  'five',
    6   =>  'six',
    7   =>  'seven'
];
$odd = array();$even = array();
array_walk($header_item,function($value,$key) use(&$odd,&$even){
    if ($key%2==0) {
        $even[]=$value;
    }
    else{
        $odd[]=$value;
    }
});
print_r($even);
print_r($odd);

将输出

Array
(
    [0] => zero
    [1] => two
    [2] => four
    [3] => six
)
Array
(
    [0] => one
    [1] => three
    [2] => five
    [3] => seven
)

Answer 2

试试这个：-

 $odd = array();
    $even = array();
    $breakrow = 0;
       foreach ($header_item as $v) {
             if ($breakrow % 2 == 0) {
               $even[] = $v;
             } else {
               $odd[] = $v;
             }
        $breakrow++;
       }
  echo '<pre>'; print_r($even).'<br>';
  echo '<pre>'; print_r($odd).'<br>';

输出：-

Array
(
    [0] => Array
        (
            [NO_INSPECTION] => 47
            [ID_CONDITION] => 1
            [NAMA_CONDITION] => DIRTY
        )
    [1] => Array
        (
            [NO_INSPECTION] => 
            [ID_CONDITION] => 
            [NAMA_CONDITION] => CLEAN
        )
)
Array
(
    [0] => Array
        (
            [NO_INSPECTION] => 47
            [ID_CONDITION] => 2
            [NAMA_CONDITION] => DAMAGE
        )
    [1] => Array
        (
            [NO_INSPECTION] => 
            [ID_CONDITION] => 
            [NAMA_CONDITION] => OFF HIRE
        )
)
