解析JSON时出错

Question

I am new to Android development. I'm sending JSON data from Android to my PHP server. But I'm getting an error:

Error parsing data org.json.JSONException: Value `<br` of type java.lang.String cannot be converted to JSONObject".

This is my PHP code:

<?php

$con = mysql_connect("localhost","custome234r","reswtdf123");
if (!$con)
    die('Could not connect: ' . mysql_error());
mysql_select_db("customer_dd_test", $con);

$jsonFeedbackResult = $_REQUEST['results'];

$flagToOpenTicket = false;            

$arrResult = json_decode(stripslashes_deep($jsonFeedbackResult));

$feedbackname = $arrResult[0]['feedbackname'];
$email = $arrResult[0]['email'];

unset($arrResult[0]);
$finalArray = array_values($arrResult);
foreach($finalArray as $key => $arrQuestionWithAnswer)
{
    if($arrQuestionWithAnswer['answer'] == 'bad' || $arrQuestionWithAnswer['answer'] == 'worst')
    {
        $flagToOpenTicket = true;
        break;
    }
}

if($flagToOpenTicket)
{
    $insertQuery = 'INSERT INTO dev_ticket(email, feedbackname) VALUES'; 
    $insertQuery .= '("'.$email.'", "'.$feedbackname.'"),';
    $executeQuery = trim($insertQuery,',');
    mysql_query($executeQuery);

}
mysql_close($con);
print(json_encode(array('response'=>$feedbackname)));

?>

Sounds like you've got some HTML embedded, probably a PHP error/warning string. The response from the server must consist of ONLY the json data. Anything else will become part of the string and cause parse errors.

Take the exact url you're hitting in android and see what it brings up in a browser.
