使用PHP创建一个xml文件
[英]Create a xml file using PHP
问题描述
I'm trying to create a XML file using PHP which would contain the following format: 
我正在尝试使用PHP创建一个XML文件，其中包含以下格式：
<outfits>
<outfit>
<head url="xxx" c="000" c2="000" z="1" />
</outfit>
</outfits>
But im confused about how i would add multiple values to a string line such as url, c, c2, z. 但我很困惑如何将多个值添加到字符串行，如url，c，c2，z。
// Function to create the outfit xml file
function create_outfit_xml(){
$xml = new DomDocument('1.0', 'UTF-8');
$outfits = $xml->createElement('outfits');
$outfits = $xml->appenChild($outfits);
$outfit = $xml->createElement('outfit');
$outfit = $xml->appenChild($outfit);
}
How would i manage to create this? 我将如何创建这个？

While using DOM is the "proper" way of doing it, DOM is also a complete pain in the rump and is an incredibly bloated way to produce XML. 虽然使用DOM是“正确”的方式，但DOM也是一个彻头彻尾的痛苦，并且是一种令人难以置信的生成XML的方式。 If you have simple XML, and you're aware of how to produce it safely, just treat it as a string to make your life easier: 如果你有简单的XML，并且你知道如何安全地生成它，那么只需将其视为一个字符串，让你的生活更轻松：
$url = htmlspecialchars($url);
$c = htmlspecialchars($c);
$xml = <<<EOL
<outfits><outfit><head url="$url" c="$c" etc... /></outfit></outfits>
EOL;

You can create an attribute. 您可以创建一个属性。
$domAttribute = $xml->createAttribute('c');
$domAttribute->value = '200';
$domElement->appendChild($element);

Using the SimpleXMLElement Class would be much ideal in this case. 在这种情况下，使用SimpleXMLElement类将非常理想。 Below is an example: 以下是一个例子：
<?php
function createOutfitXML(){
$xml = new SimpleXMLElement('<outfits></outfits>');
$head = $xml->addChild("head");
$head->addAttribute("uri", "xxx");
$head->addAttribute("c1", "000");
$head->addAttribute("c2", "2");
$head->addAttribute("z", "1");
$outfit = $xml->addChild("outfit", "jeans");
$outfit->addAttribute("color", "red");
$outfit->addAttribute("size", "32");
$xml->asXML(__DIR__ . "/xml.xml");
}
createOutfitXML();
Now, imagine you have an array containing a list of Outfits that you want to convert to an XML Document using the Function above.
THE OUTFITS ARRAY: 服装阵营：
<?php
$outfitsArray = [
"jeans" => [
[
"size" => '32',
"color" => 'Dark Blue',
"price" => 120.00,
"brand" => 'Lee',
],
[
"size" => '34',
"color" => 'Black',
"price" => 100.00,
"brand" => 'Sean Jean',
],
[
"size" => '30',
"color" => 'White',
"price" => 150.00,
"brand" => 'Pepe',
],
],
"shoes" => [
[
"size" => '40',
"color" => 'Black',
"price" => 180.00,
"brand" => 'Lee',
],
[
"size" => '44',
"color" => 'Brown',
"price" => 200.00,
"brand" => 'Sean Jean',
],
[
"size" => '42',
"color" => 'Dark Red',
"price" => 240.00,
"brand" => 'Versace',
],
]
];
THE ALGORITHM: 算法：
<?php
function createOutfitXML($outfitsArray){
$xml = new SimpleXMLElement('<outfits></outfits>');
$head = $xml->addChild("head");
$head->addAttribute("uri", "xxx");
$head->addAttribute("c1", "000");
$head->addAttribute("c2", "2");
$head->addAttribute("z", "1");
foreach($outfitsArray as $groupName=>$itemData){
foreach($itemData as $k=>$v){
$outfit = $xml->addChild("outfit");
$outfit->addAttribute("group", $groupName);
foreach($v as $key=>$value){
$outfit->addAttribute($key, $value);
}
}
}
$xml->asXML(__DIR__ . "/xml.xml");
}
createOutfitXML($outfitsArray);
The code above would create an XML Document similar in content to this:
<?xml version="1.0"?>
<outfits>
<head uri="xxx" c1="000" c2="2" z="1"/>
<outfit group="jeans" size="32" color="Dark Blue" price="120" brand="Lee"/>
<outfit group="jeans" size="34" color="Black" price="100" brand="Sean Jean"/>
<outfit group="jeans" size="30" color="White" price="150" brand="Pepe"/>
<outfit group="shoes" size="40" color="Black" price="180" brand="Lee"/>
<outfit group="shoes" size="44" color="Brown" price="200" brand="Sean Jean"/>
<outfit group="shoes" size="42" color="Dark Red" price="240" brand="Versace"/>
</outfits>
