如何将多维数组与magento中的并行行和列索引进行比较？

Question

嗨，请运行我的代码： 请查看我的预期输出。如何根据我的预期结果调整我的代码。

<?php
$arrayA=array(array("id" => 8, "name" => "test1"),  
            array("id" => 4, "name" => "test2"),  
            array("id" => 4, "name" => "test3")  
);
$arrayB=array(array("id" => 3, "domain_name" => "www.test.com","activation_key" =>"ADKLJ"),
            array("id" => 4,  "domain_name" => "www.yahoomail.com","activation_key" =>"LKLJ"),
            array("id" => 4, "domain_name" => "www.gmail.com","activation_key" =>"OLOLJ")           
);

//$places=Array();
$i=0;
foreach($arrayA as $itemA)
{
    $match=0;

    foreach($arrayB as $itemB)
    {
        if($itemA["id"]==$itemB["id"])
        {
            $arrayA[$i]["domain_name"]=$itemB["domain_name"];
            $arrayA[$i]["activation_key"]=$itemB["activation_key"];
            $match=1;
        }
    }
    if($match==0)
    {
            $arrayA[$i]["domain_name"]="";
            $arrayA[$i]["activation_key"]="";
    }
    $i++;
}
echo "<pre>";
print_r($arrayA);
echo "</pre>";

?>

输出

数组 ( [0] => 数组 ( [id] => 8 [名称] => test1 [域名] => [激活键] => )

[1] => Array
    (
        [id] => 4
        [name] => test2
        [domain_name] => www.gmail.com
        [activation_key] => OLOLJ
    )

[2] => Array
    (
        [id] => 4
        [name] => test3
        [domain_name] => www.gmail.com
        [activation_key] => OLOLJ
    )

)

但我的预期输出是

数组 ( [0] => 数组 ( [id] => 8 [名称] => test1 [域名] => [激活键] => )

[1] => Array
    (
        [id] => 4
        [name] => test2
        [domain_name] => www.yahoomail.com
        [activation_key] => LKLJ
    )

[2] => Array
    (
        [id] => 4
        [name] => test3
        [domain_name] => www.gmail.com
        [activation_key] => OLOLJ
    )

)

试试下面的方法

<?php
$arrayA=array(array("id" => 8, "name" => "test1"),  
            array("id" => 4, "name" => "test2"),  
            array("id" => 4, "name" => "test3")  
);
$arrayB=array(array("id" => 3, "domain_name" => "www.test.com","activation_key" =>"ADKLJ"),
            array("id" => 4,  "domain_name" => "www.yahoomail.com","activation_key" =>"LKLJ"),
            array("id" => 4, "domain_name" => "www.gmail.com","activation_key" =>"OLOLJ")           
);

//$places=Array();
$i=0;
foreach($arrayA as $key => $itemA)
{
    $match=0;
    $itemB = $arrayB[$key]; 
        if($itemA["id"]==$itemB["id"])
        {
            $arrayA[$i]["domain_name"]=$itemB["domain_name"];
            $arrayA[$i]["activation_key"]=$itemB["activation_key"];
            $match=1;
        }
    if($match==0)
    {
            $arrayA[$i]["domain_name"]="";
            $arrayA[$i]["activation_key"]="";
    }
    $i++;
}
echo "<pre>";
print_r($arrayA);
echo "</pre>";

?>

// store all activated domains
$activated = array();

foreach($arrayA as $key => $itemA)
{
    $match=0;

    foreach($arrayB as $itemB)
    {
        if($itemA["id"]==$itemB["id"] && !in_array($itemB["domain_name"],$activated))
        {
            $arrayA[$key]["domain_name"]=$itemB["domain_name"];
            $arrayA[$key]["activation_key"]=$itemB["activation_key"];
            $match=1;
            $activated[] = $itemB["domain_name"];
            break;
        }
    }
    if($match==0)
    {
            $arrayA[$key]["domain_name"]="";
            $arrayA[$key]["activation_key"]="";
    }
}
echo "<pre>";
print_r($arrayA);
echo "</pre>";
