'CLOSED'从php网页获取HTML代码到android中的字符串

Note ** This is not a duplicate question ,it is unlike getting HTML code from html page

I have tried all the codes posted on this site that are used to get HTML code from a page into a string in android.But from all of the codes I've tried , non worked on a url of PHP webpage, for example (http://www.jonasweb.net/samples.php) . How can I do that ?

A sample code to get HTML source as string:

HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet(url);
HttpResponse response = client.execute(request);

String html = "";
InputStream in = response.getEntity().getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
StringBuilder str = new StringBuilder();
String line = null;
while((line = reader.readLine()) != null)
{
    str.append(line);
}
in.close();
html = str.toString();

You cannot access PHP source code, that would be like giving Jimmy Saville the key to an un-guarded orphanage. There are so many secure things, like database connections that are stored in PHP source, It just isn't happening.
