Convert any php array or object to XML

README.md

Using the XMLSerializer

use App\Helpers\XMLSerializer;

$request = array("conditions" => array(
	"language" => "EN",
	"par_adt" => 1,
	"extraData" => array(
		"_attributes" => array(
			"someRandomAttribute" => "this_is_the_attribute_value"
		),
		"_value" => "This is the value of the extraData"
	),
	"People" => array(
		array("_name" => "person", "name" => "Dave"),
		array("_name" => "person", "_value" => "David")
	),
	"limit_count" => 10
));

return XMLSerializer::generateValidXmlFromArray(self::processRequest($request, $options));

This would output

<conditions>
	<language>EN</language>
	<par_adt>1</par_adt>
	<extraData someRandomAttribute="this_is_the_attribute_value"> This is the value of the extraData </extraData>
	<People>
		<person>
			<name>Dave</name>
		</person>
		<person>David</person>
	</People>
</condition>
