How to convert this XML request into array in php?

Question

I am new to SOAP. I am unable to convert this request into an array. This xml array should be in string type.

Xml request:

Put this class for converting xml to array make a file named as "xmlParser.class.php" copy paste below code to it.

After that make a file named as "test.php" that contains below code:

<?php

$ssString = '<OTA_HotelAvailRQ Version="1.0"><POS><Source><UniqueId Id="20000704abcde:105ABCDE" /></Source></POS><AvailRequestSegments><AvailRequestSegment><StayDateRange End="2011-08-15" Start="2011-08-14" />
            <RoomStayCandidates><RoomStayCandidate Quantity="1"><GuestCounts><GuestCount AgeQualifyingCode="10" Count="1" /></GuestCounts></RoomStayCandidate></RoomStayCandidates>
            <HotelSearchCriteria><Criterion><HotelRef Destination="East London, South Africa" CityCode="" CountryCode="" HotelName="" MinHotelRating="1"/><SearchCurrency>EUR</SearchCurrency>
            <AdditionalInfo Value="1" /><Language>EN</Language></Criterion></HotelSearchCriteria></AvailRequestSegment></AvailRequestSegments></OTA_HotelAvailRQ>';

include 'xmlParser.class.php';

$oXmlParser = new xmlParser();
$asArray = $oXmlParser->xml2array($ssString);
$asArray1 = $oXmlParser->xml2array($ssString,'');
$asArray2 = $oXmlParser->xml2array($ssString,1,'');
echo "<pre>";
print_r($asArray);
exit;
?>

Try this if any inconvenience please inform me if i can help you more.

Here is three different kind array you got by changing parameters like below use whatever satisfy your demand.

$asArray = $oXmlParser->xml2array($ssString);

$asArray1 = $oXmlParser->xml2array($ssString,'');

$asArray2 = $oXmlParser->xml2array($ssString,1,'');

Answer 2

You might want to try this. Create object, encode object to json, and decode json string as array.

$content = ...some xml content...

$content = json_decode(json_encode(simplexml_load_string($content)), true);
