PHP: JSON Encode and Decode

PHP have two built-in functions, json_encode() and json_decode().

Encoding and Decoding 

Encoding is used to bundle data with respect to a particular format. This process will be required to preserve data consistency. Decoding is a reverse process which reverts encoded data back to its original form.


The json_encode() function is used to encode a value to JSON format.

The json_decode() function is used to decode or convert a JSON object to a PHP object.
