json_decode( )

Used to convert JSON String into an object

• Similar to JSON.parse() at client side

• Remember! You can also convert string like array via this method into an array

• turned_in_notjson_decode

  library_books<?php
    $jsonString = '{"name":"Rahul","love":"Music"}';
    //Converting JSON String into an object
    $obj=json_decode($jsonString);
    //To access an object syntax (objectName->keyName)
    echo "My name is ".$obj->name;
  ?>

  OUTPUT
  
  My name is Rahul

/* To access all key and values of an object inside PHP */

library_books<?php
  $jsonString = '{"name":"Rahul","love":"Music"}';
  //Converting JSON String into an object
  $obj=json_decode($jsonString);
  //Accessing all key and values
  foreach($obj as $key => $value) {
    echo "Key=". $key .", Value=". $value ."<br>";
  }
?>

json_encode( )

Used to convert an object into JSON String

• Similar to JSON.stringify() at client side

• Remember! You can also convert an array via this method into a string and send it to the client

• turned_in_notjson_encode

  library_books<?php
    class profile {}
    //Creating an object of class profile
    $obj=new profile();
    $obj->name = "Rahul";
    $obj->age = 23;
    $obj->love = "Music";
    //Converting an object into JSON String
    $myJSON = json_encode($obj);
    echo "My JSON String is ".$myJSON;
  ?>

  OUTPUT
  
  My JSON String is {"name":"Rahul","age":23,"love":"Music"}

• Remember! More like PHP, there are other server scripting languages that also provides similar JSON handling methods
  
  Like in Python 3.X, in library 'json',
  json.loads() used as json_parse() and  json.dumps() used as json_stringify() at server side
