Build XML file from class in PHP - php

Question

I'm wondering if anyone knows how to build an XML file, dynamically from a list of classes?
The classes contains public variables, and look like this.
class node {
public $elementname;
}
I do note that some of the classes are named the same as variables, and in this case, the node would be a subnode element of a node:
class data {
public $dataaset;
}
class dataset {
public $datasetint;
}
would be:
<data>
<dataset>datasetint</dataset>
</data>
Maybe something in SimpleXML or something?

Answer 1

The only solution i can think of linking 2 or more unrelated class is using Annotations.
Annotations is not supported by default in PHP but currently in RFC (Request for Comments: Class Metadata) but bending the time is supported or rejected you can create yours using ReflectionClass & Comments functionality
Example If you have 3 classes like this
class Data {
/**
*
* #var Cleaner
*/
public $a;
/**
*
* #var Extraset
*/
public $b;
public $runMe;
function __construct() {
$this->runMe = new stdClass();
$this->runMe->action = "RUN";
$this->runMe->name = "ME";
}
}
class Cleaner {
public $varInt = 2;
public $varWelcome = "Hello World";
/**
*
* #var Extraset
*/
public $extra;
}
class Extraset {
public $boo = "This is Crazy";
public $far = array(1,2,3);
}
Then you can run a code like this
$class = "Data";
$xml = new SimpleXMLElement("<$class />");
getVariablesXML($class, $xml);
header("Content-Type: text/xml");
$xml->asXML('data.xml');
echo $xml->asXML();
Output
<?xml version="1.0"?>
<Data>
<Cleaner name="a">
<varInt type="integer">2</varInt>
<varWelcome type="string">Hello World</varWelcome>
<Extraset name="extra">
<boo type="string">This is Crazy</boo>
<far type="serialized">a:3:{i:0;i:1;i:1;i:2;i:2;i:3;}</far>
</Extraset>
</Cleaner>
<Extraset name="b">
<boo type="string">This is Crazy</boo>
<far type="serialized">a:3:{i:0;i:1;i:1;i:2;i:2;i:3;}</far>
</Extraset>
<runMe type="serialized">O:8:"stdClass":2:{s:6:"action";s:3:"RUN";s:4:"name";s:2:"ME";}</runMe>
</Data>
Function Used
function getVariablesXML($class, SimpleXMLElement $xml) {
$reflect = new ReflectionClass($class);
foreach ( $reflect->getProperties(ReflectionProperty::IS_PUBLIC) as $property ) {
$propertyReflect = $reflect->getProperty($property->getName());
preg_match("/\#var (.*)/", $propertyReflect->getDocComment(), $match);
$match and $match = trim($match[1]);
if (empty($match)) {
$value = $property->getValue(new $class());
if (is_object($value) || is_array($value)) {
$type = "serialized";
$value = serialize($value);
} else {
$type = gettype($value);
}
$child = $xml->addChild($property->getName(), $value);
$child->addAttribute("type", $type);
} else {
$child = $xml->addChild($match);
$child->addAttribute("name", $property->getName());
if (class_exists($match)) {
getVariablesXML($match, $child);
}
}
}
}
