JSON Lint

Usage

use Seld\JsonLint\JsonParser;

$parser = new JsonParser();
    
// returns null if it's valid json, or a ParsingException object.
$parser->lint($json);

// Call getMessage() on the exception object to get
// a well formatted error message error like this

// Parse error on line 2:
// ... "key": "value"    "numbers": [1, 2, 3]
// ----------------------^
// Expected one of: 'EOF', '}', ':', ',', ']'

// Call getDetails() on the exception to get more info.

// returns parsed json, like json_decode() does, but slower, throws
// exceptions on failure.
$parser->parse($json);

Installation

For a quick install with Composer use:

$ composer require seld/jsonlint

JSON Lint can easily be used within another app if you have a PSR-4 autoloader, or it can be installed through Composer for use as a CLI util. Once installed via Composer you can run the following command to lint a json file or URL:

$ bin/jsonlint file.json
