Question

这是我的view

我的代码：

$xml = new DOMDocument("1.0", "UTF-8");

$dateAdded = $xml->createElement("DATE_ADDED", date('Y-m-d H:i:s'));
$dateAdded = $xml->appendChild($dateAdded);

$shop = $xml->createElement("SHOP");
$shop = $xml->appendChild($shop);

foreach ($post as $key => $value) {
    foreach ($products as $product) {
        $shopproduct = $xml->createElement("SHOPPRODUCT");
        $test = $xml->createElement($key, $product[$key]);
        $test = $shopproduct->appendChild($test);
        $shopproduct = $shop->appendChild($shopproduct);
    }
}

$xml->save('test.xml');

变量$post如下所示：

array(2) {
  ["product_id"]=>
  string(1) "1"
  ["name"]=>
  string(1) "1"
}

变量$products如下所示：

array(2 {
    [0] =>
    array(2) {
        ["product_id"] =>
        string(2) "30"
        ["name"] =>
        string(12) "Canon EOS 5D"
    }
    [1] =>
    array(2) {
            ["product_id"] =>
            string(2) "47"
            ["name"]=>
            string(9) "HP LP3065"
        }
}

代码（XML文件）的结果如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<DATE_ADDED>2017-06-26 11:52:59</DATE_ADDED>
<SHOP>
    <SHOPPRODUCT>
        <product_id>30</product_id>
    </SHOPPRODUCT>
    <SHOPPRODUCT>
        <product_id>47</product_id>
    </SHOPPRODUCT>
    <SHOPPRODUCT>
        <name>Canon EOS 5D</name>
    </SHOPPRODUCT>
    <SHOPPRODUCT>
        <name>HP LP3065</name>
    </SHOPPRODUCT>
</SHOP>

如何让它看起来像这样？

<?xml version="1.0" encoding="UTF-8"?>
<DATE_ADDED>2017-06-26 11:52:59</DATE_ADDED>
<SHOP>
    <SHOPPRODUCT>
        <product_id>30</product_id>
        <name>Canon EOS 5D</name>
    </SHOPPRODUCT>
    <SHOPPRODUCT>
        <product_id>47</product_id>
        <name>HP LP3065</name>
    </SHOPPRODUCT>
</SHOP>

根据您的变量，您应首先迭代$products并在$post秒后迭代：

foreach ($products as $product) {
    $shopproduct = $xml->createElement("SHOPPRODUCT");
    foreach ($post as $key => $value) {
        $test = $xml->createElement($key, $product[$key]);
        $test = $shopproduct->appendChild($test);
        $shopproduct = $shop->appendChild($shopproduct);
    }
}

无法为每个产品导出XML
