PHP XML Creation

Create one .xml named as ofi.xml

<Productxxxxxxxxxxx>
    <ID></ID>
    <orderExternalReferenceID/>
    <submissionDate></submissionDate>
    <shopperPassword/>   
    <shopperInfo>
       
    </shopperInfo>
    <orderExtendedAttributes>
       
    </orderExtendedAttributes>
    <lineItemLevelRequest>
   
    </lineItemLevelRequest>
   
</Productxxxxxxxxxxx>


Then create php file abc.php
