php , How to decode / save a file from SOAP MTOM attachment?

Question

I'm trying to get the content / save a zipfile returned by a webservice . However It seems that the API provides the file encoded in Base64 Binary format and included in the response according to the SOAP MTOM standard. I've tried some workarounds for 2 hours so any help would be highly appreciated . The response looks like this :

--MIMEBoundaryurn_uuid_9ADB5E0C3BD2353F98133706376435374151
Content-Type: application/xop+xml; charset=utf-8; type="text/xml"

here is some messy code   ADASLKDAKDNAKJDNAKDNKJNDSAKDJNAKDJADA which is actually the file content itself

I hope this helps someone ... I simply removed all the markup code/mime type xml etc before the messy characters and saved the content as a .zip file . It's not an ideal solution but it works.
