PHP Parse stdclass对象

Question

I get the following output (var_dump) from an API call. I need to obtain the data elements or put them into an array so I can use them as individual values. I can't for the life of me work out how to do this. For example, I need the value of <PaymentReference>

Can anyone assist?

Thanks

object(stdClass)#2 (1) {
  ["GetPaymentsResult"]=>
  object(stdClass)#3 (2) {
    ["schema"]=>
    string(1754) "<xs:schema xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata" id="Payments"><xs:element name="Payments" msdata:IsDataSet="true" msdata:UseCurrentLocale="true"><xs:complexType><xs:choice minOccurs="0" maxOccurs="unbounded"><xs:element name="Payment"><xs:complexType><xs:sequence><xs:element name="PaymentID" type="xs:string" minOccurs="0"/><xs:element name="EzidebitCustomerID" type="xs:int" minOccurs="0"/><xs:element name="YourSystemReference" type="xs:string" minOccurs="0"/><xs:element name="YourGeneralReference" type="xs:string" minOccurs="0"/><xs:element name="CustomerName" type="xs:string" minOccurs="0"/><xs:element name="DebitDate" type="xs:string" minOccurs="0"/><xs:element name="PaymentRef(erence" type="xs:string" minOccurs="0"/><xs:element name="PaymentMethod" type="xs:string" minOccurs="0"/><xs:element name="PaymentSource" type="xs:string" minOccurs="0"/><xs:element name="PaymentAmount" type="xs:decimal" minOccurs="0"/><xs:element name="SetupFee" type="xs:decimal" minOccurs="0"/><xs:element name="TransactionFeeClient" type="xs:decimal" minOccurs="0"/><xs:element name="TransactionFeeCustomer" type="xs:decimal" minOccurs="0"/><xs:element name="SettlementDate" type="xs:string" minOccurs="0"/><xs:element name="InvoiceID" type="xs:int" minOccurs="0"/><xs:element name="PaymentStatus" type="xs:string" minOccurs="0"/><xs:element name="BankReturnCode" type="xs:string" minOccurs="0"/><xs:element name="BankFailedReason" type="xs:string" minOccurs="0"/><xs:element name="BankReceiptID" type="xs:string" minOccurs="0"/><xs:element name="TransactionTime" type="xs:string" minOccurs="0"/></xs:sequence></xs:complexType></xs:element></xs:choice></xs:complexType></xs:element></xs:schema>"

Answer 1

Since it is a stdClass object, you can access the values using object notation and you can use SimpleXML to parse the XML. Here is an example:

$schema = $apiResult->GetPaymentsResult->schema;
$any    = $apiResult->GetPaymentsResult->any;

$xml    = new SimpleXmlElement($any);

echo $xml->Payments[0]->Payment->PaymentReference;

I'm not sure the PaymentReference is correct, but if you see the SimpleXml examples you should be able to figure it out pretty easily.

Answer 2

You can use regular expressions. preg_match_all can help you. For example:

function preg_xa($r,$co,$n=1){
    $e=array();
    preg_match_all($r,$co,$m);
    for($i=0;$i<count($m[0]);$i++){
    $e[]=$m[$n][$i];
    }
    return $e;
}

function get_PaymentReference($content){
    return preg_xa( "/<PaymentReference>(.+)<\/PaymentReference>/simU", $content);
}

get_PaymentReference will return array of all values of PaymentReference tag.
