このエラーが発生しています

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

このエラーがどこから来ているのか判断できません.phpだと思っていましたが、別のページからjsonを取得すると正常に動作するので、エラーがどこから来ているのかわかりません.

これはphpページです

include("database.php");

$state = $_GET['state'];
$response["county"] = array();
switch ($state){
case "Select A State":

    break;
default:
    $squery = $con->prepare("SELECT * FROM states WHERE fullName = :state");
    $squery->bindParam(':state', $state, PDO::PARAM_STR);
    $squery->execute();
    $srow = $squery->fetch(PDO::FETCH_ASSOC);

    $tb = trim($srow['tbName']);
    $query = $con->prepare("SELECT DISTINCT(County) FROM `$tb` ORDER BY County ASC");
    $query->execute();

    while ($row = $query->fetch(PDO::FETCH_ASSOC)){
        $temp = array("display"=>$row['County']);
        array_push($response["county"], $temp);
        unset($temp);
    }
    break;
}
print json_encode($response);

これは私のJavaコードです

空のパラメータを使用してクエリを実行しているため、http://www.photosbychristian.com/ems/countys.php?state=Pennsylvania実際にはURLが次のURLに変換さhttp://www.photosbychristian.com/ems/countys.php?state=Pennsylvania?れます。

<br />
<b>Fatal error</b>:  Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1103 Incorrect table name ''' in /home/content/03/8587103/html/ems/countys.php:18
Stack trace:
#0 /home/content/03/8587103/html/ems/countys.php(18): PDOStatement-&gt;execute()
#1 {main}
  thrown in <b>/home/content/03/8587103/html/ems/countys.php</b> on line <b>18</b><br     />

修正するには、次の手順を実行します。

protected String doInBackground(String... args) {
    // Building Parameters
    List<NameValuePair> params = new ArrayList<NameValuePair>();
    params.add( new BasicNameValuePair( "state", "Pennsylvania" ) );
    // getting JSON string from URL
    String url = "http://www.photosbychristian.com/ems/countys.php";
    JSONObject json = stateParser.makeHttpRequest(url, "GET",
            params);

<brjson文字列をHTMLでマングリングしているようです。生のjson文字列をダンプすると、おそらくそこにPHPエラーが埋め込まれていることがわかり、json構文エラーが発生します. 例えば、あなたは受け取っています

<br />Warning: blah blah blah
[your json object here]
