soap api with betfair - php

Question

It's my first time using the SOAP API by BetFair I have created one XML file and one file that will call that file. I am not understanding how can I call this and get an output. I have created the XML file below:
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<login xmlns="http://www.betfair.com/publicapi/v3/BFGlobalService/">
<request>
<locationId xmlns="">0</locationId>
<username xmlns="">usrname</username>
<password xmlns="">password</password>
<productId xmlns="">18</productId>
<vendorSoftwareId xmlns="">0</vendorSoftwareId>
</request>
</login>
</soap:Body>
</soap:Envelope>
Now to call this file I have also created one php file to do this.
BetFair has given this link for the login api: https://api.betfair.com/global/v3/BFGlobalService.wsdl
<?php
$get_data = file_get_contents("http://pixelonsell.com/dev2/betfair/login.xml");
$b = html_entity_decode($get_data);
$data= urlencode($b);
print_r($data);
$client = new SoapClient("https://api.betfair.com/global/v3/BFGlobalService.wsdl");
$result = $client->LoginReq($data);
print_r($result);
?>
I don't know why it's not working; can you help me out with this? Thank you in advance.

I would avoid using a dedicated SOAP library; in my experience they often don't work because of inconsistencies in the ways different servers implement the SOAP specification. Use a simple HTTP/HTTPS library instead, with the following headers
SOAPAction: urn:login
Content-Length: #{myContentLength}
Content-Type: text/xml
User-Agent: #{myUserAgent}
and the following payload (assuming you're using the Free API):
<SOAP-ENV:Envelope xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<SOAP-ENV:Body>
<m:login xmlns:m="https://api.betfair.com/global/v3/BFGlobalService">
<m:request>
<username>#{myUsername}</username>
<password>#{myPassword}</password>
<locationId>0</locationId>
<vendorSoftwareId>0</vendorSoftwareId>
<productId>82</productId>
</m:request>
</m:login>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
It looks to me like you're using the wrong namespace for the login element; should be 'https://api.betfair.com/..' not 'http://www.betfair.com/..'.
Good luck.
