how to change xml tag to pascal case in php

Question

<?php
function array_to_xml(array $arr, SimpleXMLElement $xml)
{
    foreach ($arr as $k => $v) {
        is_array($v)
            ? ucwords(array_to_xml($v, $xml->addChild($k)))
            : ucwords($xml->addChild($k, $v));
    }
    return $xml;
}

$test_array = array (
  'blaPo' => '1',
  'Items' => '1',
    'another_array' => array (
        'stack' => 'overflow',
    ),
);

echo array_to_xml($test_array, new SimpleXMLElement('<root/>'))->asXML();

I want to change Tag name to Pascal case i used ucwords too its not working in the server

Answer 1

When you are using ucwords() you are both doing it on a SimpleXMLElement, but also your not storing the value returned...

is_array($v)
    ? ucwords(array_to_xml($v, $xml->addChild($k)))
    : ucwords($xml->addChild($k, $v));

Instead you should just use it when using addChild() , applying it to the name of the element being created

is_array($v)
    ? array_to_xml($v, $xml->addChild(ucwords($k)))
    : $xml->addChild(ucwords($k), $v);

Which with your test data gives...

<?xml version="1.0"?>
<root><BlaPo>1</BlaPo><Items>1</Items><Another_array><Stack>overflow</Stack></Another_array></root>
