A simple wrapper for json_encode and json_decode with exception based error handling

By Simon Hampel

Note: as of PHP v7.3 there is now a JSON_THROW_ON_ERROR option for both native commands which should effectively render this package obsolete.

Installation

To install using composer, run the following command:

composer require hampel/json

Note that there are three versions of this package, depending on the version of PHP you use:

• v2.1 supports PHP >= v5.3.3
• v2.2 supports PHP >= v5.4.0
• v2.3 supports PHP >= v5.5.0

The three versions will be maintained in parallel

Usage

All parameters are the same as specified for the PHP functions json_encode and json_decode respectively.

The main difference that this class provides is that it throws exceptions when there are errors and translates the error codes into meaningful text for you automatically.

<?php

use Hampel\Json\Json;
use Hampel\Json\JsonException;

$data = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5);

// Encode a variable as JSON:
echo Json::encode($data);

// Encode options
$options = JSON_HEX_TAG | JSON_HEX_APOS | JSON_HEX_QUOT | JSON_HEX_AMP;
echo Json::encode($data, $options);

// Decode JSON:
print_r(Json::decode('{"a":1,"b":2,"c":3,"d":4,"e":5}'));

// Error handling
try {
    Json::decode('{"a":1,"b":2,"c":3,"d":4,"e":5'); // missing }
} catch (JsonException $e) {
    echo "Oops: " . $e->getMessage();
}
