The xml file was used in the process of writing a questionnaire. If you want to know more, you can simply learn through the following link: http://www.php.cn/course/28.html

Tools used: phpstudy notepad (using utf-8 encoding without BOM)

The problems that arise are as follows: The initial code is as follows: I want to ask how many people are going to go out to Changsha to play,

<?php
header(&#39;Content-Type: text/xml&#39;);
$xmlstr="<?xml version=\"1.0\" encoding=\"utf-8\"?> 
<movies>
<movie>
<title>旅游的人数</title>
<id>1</id>
<count>350</count>
<content>长沙</content>
</movie>
<movie>
<title>旅游的人数</title>
<id>2</id>

<content>张家界</content>
</movie>
<movie>
<title>旅游的人数</title>

<count>118</count>
<content>上海</content>
</movie>
<movie>
<title>旅游的人数</title>
<id>4</id>
<count>80</count>
<content>南京</content>
</movie>
</movies>
";
$xml = simplexml_load_string($xmlstr);
$count0 = $xml->movie[0]->count;
echo $count0;
?>

Firefox On browser:

XML parsing error: Syntax error
Location: http://localhost:8080/diaocha/2.php
Line 1, Column 1: 350

Error on 360 browser:

This page contains the following errors:

error on line 1 at column 1: Document is empty

Below is a rendering of the page up to the first error

What needs to be corrected is:

Remove the first sentence: header('Content-Type: text/xml');. Get 350

2. If you need to view the xml format

The code is as follows:

<?php
header(&#39;Content-Type: text/xml&#39;);
$xmlstr="<?xml version=\"1.0\" encoding=\"utf-8\"?> 
<movies>
<movie>
<title>旅游的人数</title>
<id>1</id>
<count>350</count>
<content>长沙</content>
</movie>
<movie>
<title>旅游的人数</title>
<id>2</id>
<count>47</count>
<content>张家界</content>
</movie>
<movie>
<title>旅游的人数</title>
<id>3</id>
<count>118</count>
<content>上海</content>
</movie>
<movie>
<title>旅游的人数</title>
<id>4</id>
<count>80</count>
<content>南京</content>
</movie>
</movies>
";

The result can be obtained:
