在php中创建一个xml字符串时，我的脚本似乎停止了

I am simply trying to create this string

我只是想创建这个字符串

$post_string ='<?xml version="1.0" ?>
  <AmazonEnvelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xsi:noNamespaceSchemaLocation="amznenvelope.xsd">
  <Header>
  <DocumentVersion>1.01</DocumentVersion>
  <MerchantIdentifier>Outdoor_outlet_seller</MerchantIdentifier>
  </Header>
  <MessageType>Product</MessageType>
  <PurgeAndReplace>true</PurgeAndReplace>
  <Message>
    <MessageID>' . rand(1,1000) . '</MessageID>
    <OperationType>Update</OperationType>
  <Product>
    <SKU>'. $product->getSKU() . error_log("Got sku of product" . $product->getSKU()).'</SKU>

    <ProductTaxCode>A_GEN_TAX</ProductTaxCode>
    <LaunchDate>' . date('Y-m-d') . 'T' . date('H:i:sO') . '</LaunchDate>
  <DescriptionData>
    <Brand>'. $product->getBrand() . error_log($product->getBrand()) . '</Brand>
    <Description>' . $product->getDescription() . '</Description>
    <ItemType>Sports & Outdoors</ItemType>
  </DescriptionData>
    </Message>
  </AmazonEnvelope>';

For some reason, everything just stops when the script reaches the "Brand" line of the xml and I cannot find out why. Has anyone here had a similar problem? It would be fantastic if someone could help me out with this :) Thanks!

出于某种原因，当脚本到达xml的“Brand”行时，一切都会停止，我无法找到原因。这里有没有人有类似的问题？如果有人可以帮我解决这个问题会很棒:)谢谢！

Maybe the node value its not in a valid xml format so go and tell xml not to parse the value ... Use cdata tags <Brand><![CDATA['. $product->getBrand() . error_log($product->getBrand()) . ']]></Brand> ....

也许节点的值不是有效的xml格式，所以去告诉xml不要解析值...使用cdata标签 <！[CDATA ['。 $ product-> getBrand（）。 error_log（$ product-> getBrand（））。 ']]> ....

For reference you may want to read: [w3schools on xml CDATA]

供参考，您可能需要阅读：[x3 CDATA上的w3schools]

Your XML syntax is fine and generates something similar as below.

您的XML语法很好，并生成类似于下面的内容。

1.01 Outdoor_outlet_seller

Product
true

124
Update

prod_sku1

A_GEN_TAX
2012-01-24T23:02:33+0000

prod_brand1
prod_descr
Sports & Outdoors

My guess is that something in the values returned by the $product functions that creates the problem. Try to echo the values alone to see if anything is unexpected

我的猜测是产生问题的$ product函数返回的值。尝试单独回显值，看看是否有任何意外
