HTTP Response string from PHP to Android

Question

I am verifying a user (email address and password) in database and and echo the result.

if($num_rows == 1)
{
    $usertypeid = mysql_fetch_array($query_result);
    echo $usertypeid[0];
}
else
{
    echo "invalid_user";
}

When i test it on a normal browser it prints exactly what i want. When I do http request from android, it returns the string correct. But it has something garbage value at first byte I guess which is not visible though.

HttpResponse httpResponse = httpClient.execute(httpGet);
HttpEntity httpEntity = httpResponse.getEntity();
strResult = EntityUtils.toString(httpEntity);

Then I am comparing strResult with a final string and check if it is not a failure.

if (!strResult.equals(Konstant.HTTP_RESULT_SIGNIN_FAILURE))

So, when strResult is actually "invalid_user" the condition should not pass. But it passes.

String value of HTTP Response

Final String value

If i use "endsWith()" instead of "equals()", it works fine. or If i use substring() to eliminate first byte and then use equals, it works fine.

Can anyone please help me what's happening here?

Have you tried to encode you PHP script file with UTF-8 without BOM? — tato.rodrigo

What editor are you using? I use Notepad++ and it has a option to convert the file encoding under the "Format" menu. It worth give a try. — tato.rodrigo

You should encode the file as UTF-8 without BOM.

On Notepad++ you can do it by clicking the "Encoding" menu and then click the "Convert to UTF-8 (without BOM)" option.
