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
