convert data to json(jquery select2 plugin)

Question

I have a table users . in this table i have a field and in that field data is something like this test,test1,test2 . I am using ajax to fetch the data from this table and show it on php file.

I am able to fetch the data but due to select2 plugin. i need to make proper formatting of this data.

fetch.php

   $data = array();
    while ($result->fetch()) {
    $data['title'] = $title;
    $data['opening'] = $opening;
    $data['description'] = $description;
    $data['keywords'] = $keywords;
}
 echo json_encode($data);

keywords field have data something like this test,test1,test2

i need to make it in proper json format like this.

id:test text:test
id:test1 text:test1

so on.

Is it possible to make it like.

Answer 1

是的你可以在空数组和$ arrays =（'a'=>'b'）之内制作和二维数组然后json_encode（$ arrays）现在你得到json对象

Answer 2

Is this what are you looking for:

    while ($result->fetch()) {
    $data['title'] = $title;
    $data['opening'] = $opening;
    $data['description'] = $description;
    $data['keywords'] = $keywords;

    $data = array(
          "id" => $data['keywords'],
          "text" => $data['keywords']
    );
}
 echo json_encode($data);

Add this code in your code (new code have comment):-

<?php
    $data = array();
    while ($result->fetch()) {
        $data['title'] = $title;
        $data['opening'] = $opening;
        $data['description'] = $description;
        $data['keywords'] = $keywords;
    }
    // code need to add
    $new_data = explode(',',$data['keywords']);
    $final_data = array();
    foreach($new_data as $new_dat){
        $final_data[] = array('id'=>$new_dat,'text'=>$new_dat);
    }
    echo "<pre/>";print_r( $final_data);
    $data['keywords'] = $final_data; // assingnment
   // print json encoded data in last
    echo json_encode($data);
 ?>
