如何通过价值观和分裂关联数组过滤成两个变量？ [英] How to filter associative array by values and split into two variables?

问题描述

我想筛选关联数组，这样一个特定的键中的某些值将进入一个特定的变量。为了使这个意义上说，这里是什么，我试图做一个例子：

输入（从DB）：

 阵列
（
    [0] =＆GT;排列
           （
                [ID] =＆GT; '12'，
                [现状] =＆GT; '0'
           ）
    [1] =＆GT;排列
           （
                [ID] =＆GT; '13'，
                [现状] =＆GT; '1'
           ）
    [2] =＆GT;排列
           （
                [ID] =＆GT; '14'，
                [现状] =＆GT; '1'
           ）
）
 

输出（在PHP）：

  $ status_one =
排列
（
    [0] =＆GT;排列
           （
                [ID] =＆GT; '13'，
                [现状] =＆GT; '1'
           ）
    [1] =＆GT;排列
           （
                [ID] =＆GT; '14'，
                [现状] =＆GT; '1'
           ）
）;$ status_zero =
排列
（
    [0] =＆GT;排列
           （
                [ID] =＆GT; '12'，
                [现状] =＆GT; '0'
           ）
）
 

我知道，数组是没有语法正确，但是这是想法。我想基于在一个特定的键的值阵列之一变量分成两个独立的变量

下面是我有权。我知道这是部分错误。我试着array_filter的东西为好。

 的foreach（$作为重点=＆GT $地位; $行）{
    如果（$行['状态'] =='1'）
    {
        $ status_one [] = $键[$行]
    }
    如果（$行['状态'] =='2'）
    {
        $ status_two [] = $键[$行]
    }
}
 

解决方案

您已经接近..

  $ status_one =阵列（）;
$ status_zero =阵列（）;的foreach（$作为重点=＆GT $地位; $行）{
    如果（$行['状态'] =='1'）$ status_one [$关键] = $行;
    否则status_zero $ [$关键] = $行;
}后续代码var_dump（$ status_one，$ status_zero）;
 

I am trying to filter an associative array so that certain values within a specific key will go into a specific variable. To make sense of this, here is an example of what I'm trying to do:

Input (from DB):

Array
(
    [0] => Array
           (
                [id] => '12',
                [status] => '0'
           )
    [1] => Array
           (
                [id] => '13',
                [status] => '1'
           )
    [2] => Array
           (
                [id] => '14',
                [status] => '1'
           )
)

Output (in PHP):

$status_one = 
Array
(
    [0] => Array
           (
                [id] => '13',
                [status] => '1'
           )
    [1] => Array
           (
                [id] => '14',
                [status] => '1'
           )
);

$status_zero = 
Array
(
    [0] => Array
           (
                [id] => '12',
                [status] => '0'
           )
)

I know that the arrays are not syntactically correct, but that's the idea. I want to split one variable of arrays into two separate variables based on the value in a specific key.

Here's what I have right. I know it's partly wrong. I've tried something with array_filter as well.

foreach ($status as $key => $row) {
    if($row['status'] == '1')
    {
        $status_one[] = $key[$row];
    }
    if($row['status'] == '2')
    {
        $status_two[] = $key[$row];
    }
}

解决方案

You're close..

$status_one = array();
$status_zero = array();

foreach ($status as $key => $row) {
    if($row['status'] == '1') $status_one[$key] = $row;
    else $status_zero[$key] = $row;
}

var_dump($status_one, $status_zero);
