php怎么将二维数组键名相同的元素转为新的数组?不用for,foreach循环

enlend_443 发布于 2022-11-20 22:04

数组

如图所示是一个二维数组[别纠结,为了方便我将其转为了json], 其中type只有两个值1和2,
现在需要将type=1的元素转到$new数组中,type=2的转到$old数组中。

除了用循环还有什么方法没?

附上json:

$gang = array(
    array('id'=>1,'term_id'=>2,'name'=>'哈哈'),
    array('id'=>2,'term_id'=>1,'name'=>'嘻嘻'),
    array('id'=>1,'term_id'=>2,'name'=>'哈哈'),
    array('id'=>1,'term_id'=>3,'name'=>'哈哈'),
    array('id'=>1,'term_id'=>1,'name'=>'哈哈'),
    array('id'=>1,'term_id'=>4,'name'=>'哈哈'),
    array('id'=>1,'term_id'=>3,'name'=>'哈哈'),
    array('id'=>1,'term_id'=>2,'name'=>'哈哈'),
);
foreach ($gang as $vo) {
    $haha[$vo['term_id']][] = $vo;
}
var_dump($haha);
$data = array();
$a = array_map(function($v){ $GLOBALS['data'][$v['term_id']][] = $v;return $v;},$gang);
var_dump($GLOBALS['data']);

闭包中使用GLOBALS即可

$arr = [];//给的数组
$result = array_map(function($v){
    if($v['type'] == 1) return $v;
},$arr);
var_dump($result);

array_map(function($v){
    if($v['type'] == 1){
        $GLOBALS['new'][] = $v;
    }else if($v['type'] == 2){
        $GLOBALS['old'][] = $v;
    } 
}, json_decode($json, true));

除了不循环，我想不到别的法子，关注一下，等高人回答。

array_column — 返回数组中指定的一列 (注意版本要求。PHP 5 >= 5.5.0)

<?php
 $records  = array(
    array(
         'id'  =>  2135 ,
         'first_name'  =>  'John' ,
         'last_name'  =>  'Doe' ,
    ),
    array(
         'id'  =>  3245 ,
         'first_name'  =>  'Sally' ,
         'last_name'  =>  'Smith' ,
    ),
    array(
         'id'  =>  5342 ,
         'first_name'  =>  'Jane' ,
         'last_name'  =>  'Jones' ,
    ),
    array(
         'id'  =>  5623 ,
         'first_name'  =>  'Peter' ,
         'last_name'  =>  'Doe' ,
    )
);
 
 $first_names  =  array_column ( $records ,  'first_name' );
 print_r ( $first_names );
 ?>   

以上例程会输出：

Array
(
    [0] => John
    [1] => Sally
    [2] => Jane
    [3] => Peter
)

$b =

$newArray = array();

print_r(array_filter($b,'filtertypetwo'));

function filtertype($var)
