PHP JSON

PHP allows us to encode and decode JSON by the help of json_encode() and json_decode functions.

1) PHP json_encode

The json_encode() function returns the JSON representation of a value. In other words, it converts PHP variable (containing array) into JSON.

Syntax:

2) PHP json_decode

The json_decode() function decodes the JSON string. In other words, it converts JSON string into a PHP variable.

    ["d"] => int(4)
    ["e"] => int(5)
}
