How To Convert PHP Array To JSON Object

In this article, we will explore the process of converting a PHP array into a JSON object. We'll achieve this transformation by using the json_encode() function, an integral part of PHP that facilitates the conversion of a PHP array or object into a JSON representation.

The need to convert a PHP array into a JSON array is a common requirement in PHP or Laravel applications, particularly when working with AJAX requests. JSON responses are a practical choice for transmitting data due to their ease of use.

Throughout this article, we will present three distinct examples of how to perform this conversion from a PHP array to a JSON object, complete with accompanying output. Additionally, we will discuss how you can forcibly convert the output into a JSON object using the "JSON_FORCE_OBJECT" parameter.

In this example, we will use json_encode() function.

<?php
  
  $colors = ['Red', 'Blue', 'Green', 'Yellow', 'Pink'];
  
  $colorsJSON = json_encode($colors);
  
  echo $colorsJSON;
  
?>

Output:

["Red","Blue","Green","Yellow","Pink"]

In this example, we will use JSON_FORCE_OBJECT to encode the array object.

<?php
  
  $colors = ['Red', 'Blue', 'Green', 'Yellow', 'Pink'];
  
  $colorsJSONObject = json_encode($colors, JSON_FORCE_OBJECT);
  
  echo $colorsJSONObject;
  
?>

Output:

{"0":"Red","1":"Blue","2":"Green","3":"Yellow","4":"Pink"}

In this example, we will encode the array key and value.

<?php
  
  $address = ['city'=>'Mumbai', 'place'=>'Taj Hotel'];
  
  $jsonData = json_encode($address);
  
  echo $jsonData;
     
?>

Output:

{"city":"Mumbai","place":"Taj Hotel"}
