自定义键逗号数组分配给一个逗号数组 [英] Custom key comma array allocated to an comma array

问题描述

我有以下数组：

  $ doc_id =（3,5,4,6）
 $ requirements2 =（2,0,0,1）
  

我试着让 $ doc_id 使用以下代码 $ requirements2 的关键元素：

 <？php 
 
包含../includes/auth.php; 
包含../includes/header.php; 
 
 
 $ jat_id = intval（$ _ GET ['id']）; 
 $ div_id = intval（$ _ GET ['div_id']）; 
 
 
 $ order =SELECT * FROM document_assoc WHERE jat_id ='$ jat_id'; 
 $ result = mysql_query（$ order）; 
 $ row = mysql_fetch_array（$ result）; 
 
 $ doc_id3 = $ row ['doc_id']; 
 $ doc_id = explode（，，$ doc_id3）; 
 
 $要求= $行['要求']; 
 $ requirements2 = explode（，，$ requirements）; 
 
 foreach（$ doc_id as $ doc_id4）{
 $ requires3 = array（$ doc_id4 => $ requirement3）; 
 
 foreach（$ requirements2 as $ require3）{
 $ requirements3 = array（$ doc_id4 => $ requirement3）; 
 
 print_r（$ requirement3）; 
 
}} 
包含../includes/footer.php; 
 
？> 
  

不过，我在print_r（）上收到以下内容：
$ b数组（[3] => 2）数组（[3] => 0）数组（[3] => 0）数组（[5] => 2）数组（[5] => 2）数组阵列（[4] => 2）阵列（[4] => 0）阵列（[4] => 0）阵列> 0）Array（[6] => 0）Array（[6] => 1）

到目前为止，这是最接近的。但是显然还是错的。

从我读过的东西看来，我需要它：

1）
/ pre>

所以之后我可以通过 $ require3 [$ doc_id] 来调用它。 （$ doc_id在调用时是一个不同的变量来源，而不是在这个数组键中设置）。

如果有人能帮我解释我在做什么错2 foreach 语句我会非常感激的更好理解。

亲切的问候

$ require3 = array_combine（$ doc_id，$ requirements2）;

I have the following arrays:

$doc_id = (3,5,4,6)
$requirement2 = (2,0,0,1)

I am trying to make $doc_id the key element of $requirement2 using the following code:

<?php

include "../includes/auth.php";
include "../includes/header.php";


$jat_id = intval($_GET['id']);
$div_id = intval($_GET['div_id']);


    $order = "SELECT * FROM document_assoc WHERE jat_id = '$jat_id'";
    $result = mysql_query($order);
    $row = mysql_fetch_array($result);

    $doc_id3 = $row['doc_id'];
    $doc_id = explode(",", $doc_id3);

    $requirement = $row['requirement'];
    $requirement2 = explode(",", $requirement);

    foreach ($doc_id as $doc_id4) {
    $requirement3 = array($doc_id4=>$requirement3);

    foreach ($requirement2 as $requirement3) {
    $requirement3 = array($doc_id4=>$requirement3);

    print_r ($requirement3);

    }}
include "../includes/footer.php";

?>

However I receive the following on the print_r():

Array ( [3] => 2 ) Array ( [3] => 0 ) Array ( [3] => 0 ) Array ( [3] => 1 ) Array ( [5] => 2 ) Array ( [5] => 0 ) Array ( [5] => 0 ) Array ( [5] => 1 ) Array ( [4] => 2 ) Array ( [4] => 0 ) Array ( [4] => 0 ) Array ( [4] => 1 ) Array ( [6] => 2 ) Array ( [6] => 0 ) Array ( [6] => 0 ) Array ( [6] => 1 ) 

Which is the closest I have been so far. But obviously still wrong.

From what I have read I need it to look like this:

Array ( [3] => 2 [5] => 0 [4] => 0 [6] => 1 ) 

So that later on I can call it by $requirement3[$doc_id]. (the $doc_id will be a different variable source when calling it than from setting it within this array key).

If someone could help explain what I am doing wrong with the 2 foreach statements I would greatly appreciate the better understanding.

Kind Regards

解决方案

$requirement3 = array_combine($doc_id,$requirement2);
