RFC-8785 - https://tools.ietf.org/html/rfc8785

Inspired by https://github.com/aywan/php-json-canonicalization & https://github.com/cyberphone

Installation

composer require root23/php-json-canonicalizator

Usage

$canonicalizator = JsonCanonicalizatorFactory::getInstance();
$canonicalizedJsonString = $canonicalizator->canonicalize($input, false);
$canonicalizedJsonString = $canonicalizator->canonicalize($input, true); // hex

Example input:

{
  "numbers": [333333333.33333329, 1E30, 4.50, 2e-3, 0.000000000000000000000000001],
  "string": "\u20ac$\u000F\u000aA'\u0042\u0022\u005c\\\"\/",
  "literals": [null, true, false]
}

Output:

{"literals":[null,true,false],"numbers":[333333333.3333333,1e+30,4.5,0.002,1e-27],"string":"€$\u000f\nA'B\"\\\\\"/"}
