How do I loop through JSON array

Question

How do I traverse and display the names in the following JSON using CodeIgniter?

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');  class Search extends CI_Controller {     public function index()     {                 $json = '[{"name": "John Doe",                  "address": "115 Dell Avenue, Somewhere",                  "tel": "999-3000",                  "occupation" : "Clerk"},                  {"name": "Jane Doe",                  "address": "19 Some Road, Somecity",                  "tel": "332-3449",                  "occupation": "Student"}]';           for (int $i = 0; $i < $json.length; $i++){             ???         }         //$obj = json_decode($json);                 //$this->load->view('search_page');     } }  /* End of file search.php */ /* Location: ./application/controllers/search.php */ 

Answer 1

1) $json is a string you need to decode it first.

$json = json_decode($json); 

2) you need to loop through the object and get its members

foreach($json as $obj){    echo $obj->name;    .....  } 

Answer 2

another example:

  <?php    //lets make up some data:   $udata['user'] = "mitch";   $udata['date'] = "2006-10-19";   $udata['accnt'] = "EDGERS";   $udata['data'] = $udata; //array inside   var_dump($udata); //show what we made    //lets put that in a file   $json = file_get_contents('file.json');   $data = json_decode($json);   $data[] = $udata;   file_put_contents('file.json', json_encode($data));    //lets get our json data   $json = file_get_contents('file.json');   $data = json_decode($json);   foreach ($data as $obj) {         var_dump($obj->user);   }
