Need to write XML using PHP - how?
提问by GaxZE
I've got this basic code.
我有这个基本代码。
<chart lowerLimit='0' upperLimit='100' caption='Revenue' subcaption='US $ (1,000s)' numberPrefix='$' numberSuffix='K' showValue='1' >
<colorRange>
<color minValue='0' maxValue='50' color='A6A6A6'/>
<color minValue='50' maxValue='75' color='CCCCCC'/>
<color minValue='75' maxValue='100' color='E1E1E1'/>
</colorRange>
<value>78.9</value>
<target>80</target>
</chart>
it's used from fusionwidgets and there's no documentation on how to write this in PHP.
它是从 fusionwidgets 中使用的，并且没有关于如何在 PHP 中编写它的文档。

There is complete example with php.net/XMLWriterto produce exactly the same XML output like you posted.
php.net/XMLWriter有一个完整的示例，可以生成与您发布的完全相同的 XML 输出。
<?php
$writer = new XMLWriter();
$writer->openURI('php://output');
$writer->startDocument('1.0','UTF-8');
$writer->setIndent(4);
$writer->startElement('chart');
$writer->writeAttribute('lowerLimit', '0');
$writer->writeAttribute('upperLimit', '100');
$writer->writeAttribute('caption', 'Revenue');
$writer->writeAttribute('subcaption', 'US $ (1,000s)');
$writer->writeAttribute('numberPrefix', '$');
$writer->writeAttribute('numberSuffix', 'K');
$writer->writeAttribute('showValue', '1');
$writer->startElement('colorRange');
$writer->startElement('color');
$writer->writeAttribute('minValue', '0');
$writer->writeAttribute('maxValue', '50');
$writer->writeAttribute('color', 'A6A6A6');
$writer->endElement();
$writer->startElement('color');
$writer->writeAttribute('minValue', '50');
$writer->writeAttribute('maxValue', '75');
$writer->writeAttribute('color', 'CCCCCC');
$writer->endElement();
$writer->startElement('color');
$writer->writeAttribute('minValue', '75');
$writer->writeAttribute('maxValue', '100');
$writer->writeAttribute('color', 'E1E1E1');
$writer->endElement();
$writer->endElement();
$writer->writeElement('value','78.9');
$writer->writeElement('target','78.9');
$writer->endElement();
$writer->endDocument();
$writer->flush();
?>

My favorite way to write XML files is XMLWriter - http://php.net/xmlwriter. It's very powerfull and simple to use.
我最喜欢的编写 XML 文件的方法是 XMLWriter - http://php.net/xmlwriter。它非常强大且易于使用。
<?php
$writer = new XMLWriter();
$writer->openURI('php://output');
$writer->startDocument('1.0','UTF-8');
$writer->setIndent(4);
$writer->startElement('items');
$writer->startElement("main");
$writer->writeElement('user_id', 3);
$writer->writeElement('msg_count', 11);
$writer->endElement();
$writer->startElement("msg");
$writer->writeAttribute('category', 'test');
$writer->endElement();
$writer->endElement();
$writer->endDocument();
$writer->flush();
?>
And that piece of code will produce the following XML:
这段代码将生成以下 XML：
<?xml version="1.0" encoding="UTF-8"?>
<items>
<main>
<user_id>3</user_id>
<msg_count>11</msg_count>
</main>
<msg category="test"/>
</items>

With FluidXMLyou can generate your XML in this way.
使用FluidXML，您可以通过这种方式生成 XML。
$chart = fluidxml('chart');
$chart->attr('lowerLimit', 0)
->attr('upperLimit', 100)
->attr(...)
->add('colorRange')
->add('value', 78.9)
->add('target', 80)
->query('//colorRange')
->add('color', ['minValue' => 0, 'maxValue' => 50, ...])
->add('color', ['minValue' => 50, 'maxValue' => 75, ...])
->add('color', ['minValue' => 75, 'maxValue' => 100, ...]);

As mentioned before, setIndent sets indentation on and should be used like this:
如前所述， setIndent 设置缩进并且应该像这样使用：
$writer->setIndent(true);
if you want to set the indentation size to a different one than the default (2 spaces), you can use setIndentString:
如果要将缩进大小设置为与默认值不同的大小（2 个空格），可以使用 setIndentString：
$writer->setIndentString(" ");

SimpleXML, wich is built into PHP is the most simple solution for writing (and parsing) XML. http://php.net/manual/en/book.simplexml.php
内置于 PHP 中的 SimpleXML 是编写（和解析）XML 的最简单的解决方案。http://php.net/manual/en/book.simplexml.php
