从另一个数组的键和值创建数组

I have an array like this $items():

我有一个类似$items()的数组:

Array
    (
    [0] => Array
    (
        [id] => 1
        [first_name] => fname1
        [laste_name] => lname1
        [Age] => 20
     )
    [1] => Array
   (
        [id] => 2
        [first_name] => fname2
        [laste_name] => lname2
        [Age] => 22
    )
  )

And I want to create another array only with [id] and [Age]

我想要创建另一个数组只使用[id]和[Age]

Array
    (
    [0] => Array
    (
        [id] => 1
        [Age] => 20
     )
    [1] => Array
   (
        [id] => 2
        [Age] => 22
    )
  )

So I have tried looping like this :

我试过这样循环

$array = array();
foreach($items as $item) {
     $array['id']= $item['id'];
     $array['age']= $item['age'];

 }

But It gives only values of the last item

但它只给出最后一项的值

3 个解决方案

#1

Try with -

试一试,

$array = array();
foreach($items as $item) {
   $temp['id']= $item['id'];
   $temp['age']= $item['age'];
   $array[] = $temp;
}

#2

Try with .It'll work for you.

试试，你会有用的。

$array = array();
foreach($items as $key => $item) {
     $array[$key]['id']= $item['id'];
     $array[$key]['age']= $item['age'];

 }

#3

use this

使用这个

$array = array();

$new_array = array();

foreach($items as $item) {
     $array['id']= $item['id'];
     $array['age']= $item['age'];
     $new_array[] = $array;
 }

print_r($new_array);

Your result is :

你的结果是:

  Array
    (
    [0] => Array
    (
        [id] => 1
        [Age] => 20
     )
    [1] => Array
   (
        [id] => 2
        [Age] => 22
    )
  )
