Creating JSON in PHP

This recipe will explain how JSON can be created from PHP arrays and objects.

Getting ready

Create a new folder inside the Chapter4 directory and name it as Recipe1.

How to do it...

1. Create a file and save it by the name index.php in the Recipe1 folder.

2. Write the PHP code that creates a JSON string from an array.

   <?php
     $travelDetails = array(
       'origin' => 'Delhi',
       'destination' => 'London',
       'passengers' => array
         (
           array('name' => 'Mr. Perry Mason', 'type' => 'Adult', 'age'=> 28),
           array('name' => 'Miss Irene Adler', 'type' => 'Adult', 'age'=> 28)
         ),
       'travelDate' => '17-Dec-2010'
     );
     echo json_encode($travelDetails);
   ?>

3. Run the file in your browser. It will show a JSON string as output on screen. After indenting the result will look like the following:

    {
    "origin":"Delhi",
   "destination":"London",
   "passengers":
   [
   
     {
       "name":"Mr. Perry Mason",
       "type":"Adult",
       "age":28
    },
     {
       "name...
