Parse XML to Array with SimpleXML - php

Question

I've that xml structure retrieving from device
<packet>
<info action="fiscalmemory" fiscalmemorysize="1048576" recordsize="464" fiscal="1" uniqueno="ABC12345678" nip="123-456-78-90" maxrecordscount="2144" recordscount="7" maxreportscount="1830" reportscount="4" resetmaxcount="200" resetcount="0" taxratesprglimit="30" taxratesprg="1" currencychangeprglimit="4" currencychangeprg="0" fiscalstartdate="dd-mm-yyyy hh:dd:ss" fiscalstopdate="dd-mm-yyyy hh:dd:ss" currencyname="PLN" />
<ptu name="A" bres="Nobi">123.23</ptu>
<ptu name="B">123.23</ptu>
<ptu name="D">8</ptu>
<sale>999.23</sale>
</packet>
simpleXml does't see ptu's attributes
$array = simplexml_load_string($xml);
print_r($array);
It prints
SimpleXMLElement Object
(
[info] => SimpleXMLElement Object
(
[#attributes] => Array
(
[action] => fiscalmemory
[fiscalmemorysize] => 1048576
[recordsize] => 464
[fiscal] => 1
[uniqueno] => ABC12345678
[nip] => 123-456-78-90
[maxrecordscount] => 2144
[recordscount] => 7
[maxreportscount] => 1830
[reportscount] => 4
[resetmaxcount] => 200
[resetcount] => 0
[taxratesprglimit] => 30
[taxratesprg] => 1
[currencychangeprglimit] => 4
[currencychangeprg] => 0
[fiscalstartdate] => dd-mm-yyyy hh:dd:ss
[fiscalstopdate] => dd-mm-yyyy hh:dd:ss
[currencyname] => PLN
)
)
[ptu] => Array
(
[0] => 123.23
[1] => 123.23
[2] => 8
)
[sale] => 999.23
)
As we can see ptu doesn't contain attributes :/
I also tried parse it with recursive function because children also may contain chilren but without success :/
Could anybody point to me why SimpleXML doesn't take ptu's attributes and also share any parsing function?
Thanks in advance.

As regards Nigel Ren I made that function
function parseXMLtoArray($xml){
$x = simplexml_load_string($xml);
$result = [];
function parse($xml, &$res){
$res['name'] = $xml->getName();
$res['value'] = $xml->__toString();
foreach ($xml->attributes() as $k => $v){
$res['attr'][$k] = $v->__toString();
}
foreach($xml->children() as $child){
parse($child, $res['children'][]);
}
}
parse($x, $result);
return $result;
}
$resArray = parseXMLtoArray($rawXml);
print_r($resArray);
this returns such array
Array
(
[name] => packet
[value] =>
[attr] => Array
(
[crc] => BKJFKHKD54
)
[children] => Array
(
[0] => Array
(
[name] => info
[value] =>
[attr] => Array
(
[action] => fiscalmemory
[fiscalmemorysize] => 1048576
[recordsize] => 464
[fiscal] => 1
[uniqueno] => ABC12345678
[nip] => 123-456-78-90
[maxrecordscount] => 2144
[recordscount] => 7
[maxreportscount] => 1830
[reportscount] => 4
[resetmaxcount] => 200
[resetcount] => 0
[taxratesprglimit] => 30
[taxratesprg] => 1
[currencychangeprglimit] => 4
[currencychangeprg] => 0
[fiscalstartdate] => dd-mm-yyyy hh:dd:ss
[fiscalstopdate] => dd-mm-yyyy hh:dd:ss
[currencyname] => PLN
)
)
[1] => Array
(
[name] => ptu
[value] => 123.23
[attr] => Array
(
[name] => A
)
)
[2] => Array
(
[name] => ptu
[value] => 123.23
[attr] => Array
(
[name] => B
)
)
[3] => Array
(
[name] => ptu
[value] => 8
[attr] => Array
(
[name] => D
)
)
[4] => Array
(
[name] => sale
[value] => 999.23
)
)
)
Is this correct?
Thanks again Nigel

When loading with SimpleXML, using print_r() gives only an idea of the content and doesn't have the full content. If you want to see the full content then use ->asXML()...
$array = simplexml_load_string($xml);
echo $array->asXML();
To check the attributes of <ptu> element, (this just gives the first one)...
echo $array->ptu[0]['name'];
This uses ->ptu to get the <ptu> element and takes the first one [0] and then takes the name attribute using ['name'].
