Reading JSON in PHP

Opposite to the previous recipe, this recipe will explain how JSON strings can be read in PHP and converted to objects or arrays. Decoding JSON strings is very easy in PHP with its JSON functions.

Getting ready

Create a new folder named Recipe2 in the Chapter4 directory.

How to do it...

1. Create a file named index.php in Recipe2 folder.

2. Now try to convert a JSON string to object using json_decode() method. After that, print the resulting object on screen. For json_decode(), you can use the output from previous recipe which is a valid JSON string.

   <?php
   $json = <<<JSON
   {
     "origin":"Delhi",
     "destination":"London",
     "passengers":
     [
       {
         "name":"Mr. Perry Mason",
         "type":"Adult",
         "age":28
       },
       {
         "name":"Miss Irene Adler",
         "type":"Adult",
         "age":25
       }
     ],
     "travelDate":"17-Dec-2010"
   }
   JSON;
   echo '<pre>';
   $objJson = json_decode($json);
   print_r ($objJson);
   echo '</pre>';
   ?>

3. Run the index.php file in the browser...
