Error after callApi (result of buildPaymentPageUrl)

[bicibg]

Pull request: #3

The sent request does either not contain the request parameter 'id' or it is invalid (e.g. wrong format).

The call from API returns this error. Upon further inspection, I found that this is caused by the buildRequestUrl method which uses http_build_query function which by default uses '&' as a separator. Normally if posting to another php5.3 machine this will not be a problem.

But if you post to a server with a newer PHP version or tomcat java server or something else the & might not be handled properly.

To overcome this specify:

http_build_query($array, '', '&');

and NOT

http_build_query($array);

in buildRequestUrl method. More specifically, change buildRequestUrl method in ApiClient.php to the following:

        /**
	 * Returns the request url.
	 *
	 * @param string $path the request path
	 * @param array $queryParams an array of query parameters
	 * @return string
	 */
	private function buildRequestUrl($path, $queryParams) {
		$url = $this->getBasePath() . $path;
		if (!empty($queryParams)) {
			$url = ($url . '?' . http_build_query($queryParams, '', '&'));
		}
		return $url;
	}

I have created a new release which fixes the issue. However the underlying problem is actually that you can override the arg-separator.output via the PHP ini. So the solution remains the same but it is not happening randomly and it has actually not that much to do with the remote server.
