Question

它有Android应用程序向数据库添加数据，但是当您在阿拉伯人中输入数据时，节目 ”？？？？？” 。我尝试了所有方法。

文件config.inc.php：

<?php 

$username = "*****"; 
$password = "****"; 
$host = "*****"; 
$dbname = "*****"; 

$options = array(PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8'); 

try 
{ 
    $db = new PDO("mysql:host={$host};dbname={$dbname};charset=utf8", $username, $password, $options);
mysql_set_charset('utf8');
} 
catch(PDOException $ex) 
{ 
    die("Failed to connect to the database: " . $ex->getMessage()); 
} 


$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);     
$db->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_ASSOC); 

if(function_exists('get_magic_quotes_gpc') && get_magic_quotes_gpc()) 
{ 
    function undo_magic_quotes_gpc(&$array) 
    { 
        foreach($array as &$value) 
        { 
            if(is_array($value)) 
            { 
                undo_magic_quotes_gpc($value); 
            } 
            else 
            { 
                $value = stripslashes($value); 
            } 
        } 
    } 

    undo_magic_quotes_gpc($_POST); 
    undo_magic_quotes_gpc($_GET); 
    undo_magic_quotes_gpc($_COOKIE); 
} 
?>

加法文件：

<?php

require("config.inc.php");

$query = "INSERT INTO news (  news_date, news_title, news_body ) VALUES ( :news_date, :news_title, :news_body ) ";
$query_params = array(
    ':news_date'  => $_POST['news_date'],
    ':news_title' => $_POST['news_title'],
    ':news_body'  => $_POST['news_body']
);



try 
{
    $stmt   = $db->prepare($query);
    $result = $stmt->execute($query_params);

}
catch (PDOException $ex) 
{
    $response["success"] = 0;
    $response["message"] = "Database Error. Couldn't add News!";
    die(json_encode($response));
}

$response["success"] = 1;
$response["message"] = "News Successfully Added!";
echo json_encode($response);
?>

在Android项目中： Java文件：

public class addnews extends Dialog {

private Activity mActivity;

private EditText mNewsTitleET;
private EditText mNewsET;

private Button mPublishBtn;
public String username;

JSONParser jsonParser = new JSONParser();

private String ADD_URL =
        "http://yazanyazan3.esy.es/newssite/addnews.php";

public addnews(Activity mActivity)
{
    super(mActivity);
    this.mActivity = mActivity;
}

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.activity_addnews);

    mNewsTitleET = (EditText) findViewById(R.id.title_news);
    mNewsET      = (EditText) findViewById(R.id.news_box);
    mPublishBtn  = (Button) findViewById(R.id.publish_btn);

    Bundle use =getIntent().getExtras();
    username = use.getString("name");

    mPublishBtn.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View view)
        {
            attempAdding();
        }
    });
}

private void attempAdding()
{
    if (!mNewsTitleET.getText().toString().equals("") &&
            !mNewsET.getText().toString().equals(""))
    {
        new AddNewsTask().execute();
    }
    else
    {
        Toast.makeText(mActivity.getApplicationContext(),
                "All fields are requires", Toast.LENGTH_LONG).show();
    }
}


public Intent getIntent() {
    return mActivity.getIntent();
}


private class AddNewsTask extends AsyncTask<Void, Void, Boolean>
{
    private ProgressDialog mProgressDialog;

    private JSONObject jsonObjectResult = null;

    private String error;

    @Override
    protected void onPreExecute()
    {
        super.onPreExecute();
        mProgressDialog = ProgressDialog.show(addnews.this.getContext(),
                "Processing...", "Adding new news", false, false);
    }

    @Override
    protected Boolean doInBackground(Void... params)
    {
        DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
        Date date = new Date();


        List<NameValuePair> pairs = new ArrayList<NameValuePair>();
        pairs.add(new BasicNameValuePair("news_user",username));
        pairs.add(new BasicNameValuePair("news_date", dateFormat.format(date).toString()));
        pairs.add(new BasicNameValuePair("news_title", mNewsTitleET.getText().toString()));
        pairs.add(new BasicNameValuePair("news_body", mNewsET.getText().toString()));


        jsonObjectResult = jsonParser.makehttprequest(ADD_URL+"?user="+username+"", pairs);

        if (jsonObjectResult == null)
        {
            error = "Error in the connection";
            return false;
        }

        try
        {
            if (jsonObjectResult.getInt("success") == 1)
            {
                error = jsonObjectResult.getString("message");
                return true;
            }
            else
                error = jsonObjectResult.getString("message");

        }
        catch (Exception ex)
        {

        }

        return false;
    }

    @Override
    protected void onPostExecute(Boolean aBoolean)
    {
        super.onPostExecute(aBoolean);
        mProgressDialog.dismiss();
        Toast.makeText(mActivity.getApplicationContext(), error, Toast.LENGTH_LONG).show();
        dismiss();
    }
} }

在数据库中，我选择utf8。并尝试了所有的解决方案都没有用。请帮忙。

希望这些提示有所帮助：

尝试在添加文件中添加静态文本到数据库中（不要从请求中读取），这样你就可以将问题分成两部分，你可以看到问题是从android客户端到PHP服务器，还是从PHP服务器到数据库如：

<?php

/*
  please type the Arabic string(salam) with your own keyboard and do not 
  copy my version because I used Persian keyboard.
*/
$arabic_string = 'سلام';

file_put_contents("arabic_file", $arabic_string);

$query_params = array(
    ':news_date'  => $_POST['news_date'],
    ':news_title' => $_POST['news_title'],
    ':news_body'  => $arabic_string
);

?>

现在检查＆＃34; arabic_file＆＃34;内容和数据库。

- 如果文件不正确（包含乱码）那么问题来自你的php服务器（也许它不支持阿拉伯语，...）。

- 如果数据库不正常（再次乱码）那么问题可能是您的数据库或PHP的PDO将数据插入数据库的方式，您应该为您的连接指定编码，如：

$connection_str = "mysql:host=$host;dbname=$db;charset=utf8";

- 如果一切正常，那么问题就在于阿拉伯字符串来自你的Android设备。
