将php数据发送到Java桌面应用程序

Question

I would like to send data from a php script to a java desktop application. The php data is retrieved from a database in a SELECT * FROM xxxxx. I would like to pass these values to java for displaying.

I know I can receive data from php in java through the following statement

String buffer;

    in = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));
    while((buffer = in.readLine()) != null){
        System.out.println(buffer);
    }

However what if I want to capture specific values like firstname , lastname, age, occupation etc etc. How can I do that in java not android.

Any help would be much appreciated!

Answer 1

Use JSON as a structure to transport your data. In you PHP script have something like this, if you are using PDO

$pdo=new PDO("mysql:dbname=database;host=127.0.0.1","user","password");
$statement=$pdo->prepare("SELECT * FROM table");
$statement->execute();
$results=$statement->fetchAll(PDO::FETCH_ASSOC);
$json=json_encode($results);
echo $json;

This is the way I do it in my Android apps.

Android has JSON libraries to help you process the JSON.

Use Json to do it , first you need to get data from table

       $dbname  = "dbname";
        $host       = "localhost";
        $user       = "root";
        $pass       = "";
        $con        = new PDO("mysql:host=$host;dbname=$dbname",$user,$pass);
        $select     = $con->prepare("select * from your_tablename");
        $execute    = $select->execute();
        foreach ($select as $selects) {
             $fname[]   = array("fname"=>$selects['fname']);
             $lname[]   = array("lname"=>$selects['lname']);
             $age[]     = array("age"=>$selects['age']);     
        }
        $new_array      = array_merge($fname,$lname);
        echo json_encode($new_array);

and in Java side you need to decode the json and use multi dimenssional array to retrieve the values

  eg : array[0]['fname'].

Hope it will help you
