Introduction about JSON

JSON stands for JavaScript Object Notation.
JSON is used for data exchanging between browser and server.
JSON basically is text and written in JS object Notation

When we sending or exchanging the data between server and browser the data must be in text format.

And JSON is text and we can be converting it into JS array, PHP array, and PHP object. In vise versa, we convert PHP array to JSON format and send it into the server.

JSON Syntax

{
  "first_name" : "Bikash",
  "last_name" : "Panda",
  "location" : "LKO"
}

{

"first_name" : "Bikash",

"last_name" : "Panda",

"location" : "LKO"

}

Introduction to PHP Array

I know you all know about PHP array. The array is also a special type of variable that can store one or more values at a time.

In PHP there are 3 types of array ,

Indexed arrays – Arrays with a numeric index
Associative arrays – Arrays with named keys
Multidimensional arrays – Arrays containing one or more arrays

PHP Array Syntax

$names = array("John", "DOE", "Hakuna");

1	$names = array("John", "DOE", "Hakuna");

Convert JSON to Array PHP [ JSON decode ]

Now we check how we Convert JSON string to Array with example. From the above words, you all know about what is an array and JSON and how we declare JSON and array in PHP.

For converting JSON to array in PHP we use JSON decode json_decode() function. So we check with a working example below,

Example JSON to Array PHP

<?php
  // JSON string
  $someJSON = '[{"first_name":"Bikash","gender":"male"},{"first_name":"Dev","gender":"male"},{"first_name":"John Doe","gender":"female"}]';

  // Convert JSON string to Array
  $someArray = json_decode($someJSON, true);
  echo "<pre>";
  print_r($someArray); // Dump all data of the Array
  echo $someArray[0]["first_name"]; // Access Array data
?>

<?php

// JSON string

$someJSON = '[{"first_name":"Bikash","gender":"male"},{"first_name":"Dev","gender":"male"},{"first_name":"John Doe","gender":"female"}]';

// Convert JSON string to Array

$someArray = json_decode($someJSON, true);

echo "<pre>";

print_r($someArray); // Dump all data of the Array

echo $someArray[0]["first_name"]; // Access Array data

Example JSON to PHP Object

<?php
  // JSON string
  $someJSON = '[{"first_name":"Bikash","gender":"male"},{"first_name":"Dev","gender":"male"},{"first_name":"John Doe","gender":"female"}]';

  // Convert JSON string to Object
  $someObject = json_decode($someJSON);
  echo "<pre>";
  print_r($someObject);      // Dump all data of the Object
  echo $someObject[0]->first_name; // Access Object data
?>

<?php

// JSON string

$someJSON = '[{"first_name":"Bikash","gender":"male"},{"first_name":"Dev","gender":"male"},{"first_name":"John Doe","gender":"female"}]';

// Convert JSON string to Object

$someObject = json_decode($someJSON);

echo "<pre>";

print_r($someObject); // Dump all data of the Object

echo $someObject[0]->first_name; // Access Object data

You can copy that code and paste it with PHP tag here for live view,
