Question

我的代码可以正常工作，但看起来很凌乱，尤其是我需要将foreach循环重复6次，然后将每个循环的输出数组合并到一个多维数组中，下面的代码展示了如何编写循环2次。

$prodo = array();
$uk_array = array();
$de_array = array();
// set counter you want to iterate over.
$j =0;
$step = 5; // set the step value (in your case it will 50.) 
$n = count($asins_array)/$step;

$associate_id = "xxxxxxxxxxx";
$access_key = "xxxxxxxxxx";
$secret_key = "xxxxxxxxxx";

for($i = 0 ;$i<$n;$i++)
{

    $asin = implode(',',array_slice($asins_array,$j,$step));
    $j = $j+$step; // increment counter by to step position. 
    echo "<pre>";
    print_r($asin); // this is the collection you want. save it or use directly   
echo "</pre>";


//////////////////// How to put that code from this point to the point idicated below in a function wth arguments///// 


    $amazon = new AmazonAPI($associate_id , $access_key, $secret_key , "amazon.co.uk");
    $item = $amazon->item_lookup($asin);

    $url = $amazon->build_url();
    echo $url;



    foreach($amazon->xml->Items->Item as $item)
    {
        $amz_asin =   (string)$item->ASIN;
        $amz_price = number_format($item->OfferSummary->LowestNewPrice->Amount/100, 2);
        $amz_title =   (string)$item->ItemAttributes->Title;
        //$amz_desc =   (string)$item->EditorialReviews->EditorialReview->Content;
        $amz_feature =   (string)$item->ItemAttributes->Feature;

        $product_array =  array ("UK" => array ("Title" => $amz_title , "Price" => $amz_price));

        $uk_array [$amz_asin] = $product_array;

    }

/////////////////

    $amazon = new AmazonAPI($associate_id , $access_key, $secret_key , "amazon.de");
    $item = $amazon->item_lookup($asin);

    $url = $amazon->build_url();
    echo $url;


    foreach($amazon->xml->Items->Item as $item)
    {
        $amz_asin =   (string)$item->ASIN;
        $amz_price = number_format($item->OfferSummary->LowestNewPrice->Amount/100, 2);
        $amz_title =   (string)$item->ItemAttributes->Title;
        //$amz_desc =   (string)$item->EditorialReviews->EditorialReview->Content;
        $amz_feature =   (string)$item->ItemAttributes->Feature;

        $product_array =  array ("DE" => array ("Title" => $amz_title , "Price" => $amz_price));

        $de_array [$amz_asin] = $product_array;

        ///////////////


    }


}


$prodo = array_merge_recursive($de_array , $uk_array );

print_r ($prodo);

我试图这样做，但没有成功，当我仅添加以下行

$uk_array [$amz_asin] = amz_xml_array('amazon.co.uk','UK',$asin);

并打印该变量，我会正确地获得英国数组

当我用下面的行替换上面的uk行时，我得到了正确的de数组 $ de_array [$ amz_asin] = amz_xml_array（'amazon.de'，'DE'，$ asin）;

但是当我添加两行并尝试在循环外使用array_merge_recursive合并它们时，我得到部分合并好的数组数组，并且部分看上去很乱，我试图通过保留uk和de变量来测试它，只打印一个他们中的一些没有合并，我得到了来自de数组的UK数组！

$product_details = array();
function amz_xml_array ($amazon_domain,$arr_country_code,$asin) {
    global $product_details;

    $associate_id = "xxxxxxxxxx";
    $access_key = "xxxxxxxxxx";
    $secret_key = "xxxxxxxxxx";

    $amazon = new AmazonAPI($associate_id , $access_key, $secret_key , $amazon_domain);
    $item = $amazon->item_lookup($asin);

    $url = $amazon->build_url();
    echo $url;

    foreach($amazon->xml->Items->Item as $item)
    {
        $amz_asin =   (string)$item->ASIN;
        $amz_price = number_format($item->OfferSummary->LowestNewPrice->Amount/100, 2);
        $amz_title =   (string)$item->ItemAttributes->Title;
        $product_array =  array ($arr_country_code => array ("Title" => $amz_title , "Price" => $amz_price)); //Build array from Amazon API XML
        $product_details [$amz_asin] = $product_array;      //get the array outside the loop
    }

    return $product_details;
}




$uk_array = array();
$de_array = array();

// set counter you want to iterate over.
$j =0;
$step = 5; // set the step value (in your case it will 50.) 
$n = count($asins_array)/$step;

for($i = 0 ;$i<$n;$i++) {
    $asin = implode(',',array_slice($asins_array,$j,$step));
    $j = $j+$step; // increment counter by to step position. 
    echo "<pre>";
    print_r($asin); // this is the collection you want. save it or use directly   
echo "</pre>";

$uk_array [$amz_asin] = amz_xml_array('amazon.co.uk','UK',$asin);
$de_array [$amz_asin] = amz_xml_array('amazon.de','DE',$asin);

}

//$prodo = array_merge_recursive($de_array , $uk_array );
echo "<pre>";
print_r ($uk_array);
echo "</pre>";

所以我想知道我是否做错了什么？！

由于您没有重新初始化linux数组，因此您可能会混淆细节。您应该尽量避免一般使用$product_details，这是为什么一个例子。

而是在每个循环中创建一个新数组...

global

如何将该代码放入可重用的函数中？
