PHP body param of name "body" gets nullified

[who]

When using a parameter of name "body", the PHP generator nullifies it.

This is caused by variable name collision in the default PHP mustache template.

This Swagger 2.0 schema snippet will repro the bug:

{
...
        "parameters": [
          {
            "in": "body",
            "name": "body",
            "description": "Body object",
            "required": true,
            "schema": {
              "$ref": "#/definitions/Body"
            }
          }
...
}

Resulting generated code:

public function createBody($body) {
    // parse inputs
    $resourcePath = "/bodies";
    $resourcePath = str_replace("{format}", "json", $resourcePath);
    $method = "POST";
    $httpBody = '';
    $queryParams = array();
    $headerParams = array();
    $formParams = array();
    $_header_accept = 'application/json';
    if ($_header_accept !== '') {
        $headerParams['Accept'] = $_header_accept;
    }
    $_header_content_type = array('application/json',);
    $headerParams['Content-Type'] = count($_header_content_type) > 0 ? $_header_content_type[0] : 'application/json';

    // body params
    $body = null;
    if (isset($body)) {
        $body = $body;
    }

    // for model (json/xml)
    if (isset($body)) {
        $httpBody = $body; // $body is the method argument, if present
    }

    // for HTTP post (form)
    if (strpos($headerParams['Content-Type'], "application/x-www-form-urlencoded") > -1) {
        $httpBody = http_build_query($formParams);
    }

    // make the API Call
    $response = $this->apiClient->callAPI($resourcePath, $method,
        $queryParams, $httpBody,
        $headerParams);

    if(! $response) {
        return null;
    }

    $responseObject = $this->apiClient->deserialize($response, 'Body');
    return $responseObject;
}

As you can see, $body = null will wipe out the passed-in value.

Closing this, as it's fixed now.
