Question

我正在尝试将PHP文件格式设置为由我的网站生成的XML文件，然后删除所有冗余信息并输出CSV文件。我有一切正常工作，除非有多个项目，只有第一个项目正在提交。这是我正在使用的XML和PHP，我无法弄清楚为什么它没有使用foreach命令循环。

XML

<line-items type="array">
<line-item>
    <fulfillment-service>manual</fulfillment-service>
    <fulfillment-status nil="true"/>
    <gift-card type="boolean">false</gift-card>
    <grams type="integer">5000</grams>
    <id type="integer">56789</id>
    <price type="decimal">199.99</price>
    <product-id type="integer">123456</product-id>
    <quantity type="integer">1</quantity>
    <requires-shipping type="boolean">true</requires-shipping>
    <sku>SKU2006-001</sku>
    <taxable type="boolean">true</taxable>
    <title>Sledgehammer</title>
    <variant-id type="integer">654321</variant-id>
    <variant-title nil="true"/>
    <vendor nil="true"/>
    <name>Sledgehammer</name>
    <variant-inventory-management nil="true"/>
    <properties type="array">
    </properties>
    <product-exists type="boolean">true</product-exists>
    <fulfillable-quantity type="integer">1</fulfillable-quantity>
    <tax-lines type="array"/>
</line-item>
<line-item>
    <fulfillment-service>manual</fulfillment-service>
    <fulfillment-status nil="true"/>
    <gift-card type="boolean">false</gift-card>
    <grams type="integer">500</grams>
    <id type="integer">98765</id>
    <price type="decimal">29.95</price>
    <product-id type="integer">12345</product-id>
    <quantity type="integer">1</quantity>
    <requires-shipping type="boolean">true</requires-shipping>
    <sku>SKU2006-020</sku>
    <taxable type="boolean">true</taxable>
    <title>Wire Cutter</title>
    <variant-id type="integer">54321</variant-id>
    <variant-title nil="true"/>
    <vendor nil="true"/>
    <name>Wire Cutter</name>
    <variant-inventory-management nil="true"/>
    <properties type="array">
    </properties>
    <product-exists type="boolean">true</product-exists>
    <fulfillable-quantity type="integer">1</fulfillable-quantity>
    <tax-lines type="array"/>
</line-item>

用PHP格式化它;

    $line_items = $order->{'line-items'};
$line_item = $order->{'line-items'}->{'line-item'};
$count_line_item = count($line_item);
    $item_sku = $order->{'line-items'}->{'line-item'}->{'sku'};
    $item_qty = $order->{'line-items'}->{'line-item'}->{'quantity'};
    $ship_to_email = $order->{'email'};
    $item_price = $order->{'line-items'}->{'line-item'}->{'price'};

    $item_array = array($line_item);

    foreach($item_array as $line_item) {

        $csv =
            $order_number.','.
            /*$order_contact_id.','.*/
            $first_name.','.
            $last_name.','.
            $order_date.','.
            $shipping_address1.','.
            $shipping_address2.','.
            $shipping_city.','.
            $shipping_province.','.
            $shipping_country.','.
            $shipping_zip.','.
            $shipping_phone.','.
            $item_sku.','.
            $item_qty.','.
            $ship_to_email.','.
            $item_price;

    };

我希望输出类似 1234，Steve，Shipper，2015-01-09 08：40：30,123 Shipping Street ,, Shippington，KY，US，K2P0S0,555-555- SHIP，SKU2006-001,1，jon @ doe.ca，199.99 但如果有多个项目则连续。

思想？

根据您需要/想要的转换次数，它可以像

一样简单

<?php
$fp = fopen('php://stdout', 'wb');

$items = new SimpleXMLElement( data() );
foreach( $items->{'line-item'} as $item ) {
    fputcsv($fp, iterator_to_array($item));
}


function data() {
    return <<< eox
<line-items type="array">
<line-item>
    <fulfillment-service>manual</fulfillment-service>
    <fulfillment-status nil="true"/>
    <gift-card type="boolean">false</gift-card>
    <grams type="integer">5000</grams>
    <id type="integer">56789</id>
    <price type="decimal">199.99</price>
    <product-id type="integer">123456</product-id>

</line-item>
</line-items>
eox;
}
