Data send from android application to PHP page is null

PHP

Hi all,

I have an android application which communicates with a php page to insert data into mysql table. it was functioning well on an windows server. Recently we were forced to move the application to a linux sever for some other reason. After that some error is returned. When I cross checked every thing, no data is received from the android application to the php page.
Android send data using post method. Content type is "application/x-www-form-urlencoded". Data is encoded using UTF-8 format.

I can see the variables values correctly in android app. But when we fetch it in Php page "null" is returned. When we assign a value in php page it works

The same code was working finely on windows server. So I have concluded that problem was with the server settings.
Default charset of server was not UTF-8 and I asked server team to set it so and they did the same adding the following code .htaccess file

// .htaccess code

suPHP_ConfigPath /home/mydom/php.ini

Is there any other setting to be changed or added in .htacess to get it working


Android code

String pdts=jsonobj.toString();
String citms=citm.toString();

url = new URL("http://www.mydom.in/myphppage.php");

String pdtsenc=URLEncoder.encode(pdts, "UTF-8");
String citmsenc=URLEncoder.encode(citms, "UTF-8");
String param = "cdt=" + pdtsenc +
"&idt=" + citmsenc;
conn=(HttpURLConnection)url.openConnection();
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setFixedLengthStreamingMode(param.getBytes().length);
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
PrintWriter out = new PrintWriter(conn.getOutputStream());
out.print(param);
out.close();

Php code

$cdt = urldecode($_POST['cdt']);
 
//the above code  returns null
 
$cdt = json_decode($cdt , true); 
 
$idt = urldecode($_POST['idt']);
 
// the above code returns null
 
$idt = json_decode($idt , true);

Please suggest a solution for this

Thanks in Advance!!!
