You can use HttpUrlConnection to connect to the php script and BufferedInputStream to get the data

URL url= new URL("http://...yourfile.php");
HttpUrlConnection con= (HttpURLConnection) url.openConnection();
con.setDoInput(true);

InputStream inputStream = new BufferedInputStream(con.getInputStream());
String result = readStream(inputStream); // s now contains the value you need
