This JSON minifier written in PHP is based on the PHP part of JSON.minify script by Kyle Simspon. This project being functional entirely relies on Kyle's work: this project basically wraps Kyle's script in a class, and adds some fancy fashion to that class, such as publication on Packagist for availability with Composer and documentation generated with PhpDocumentor. See original author's blog post if you want to know more.
This minifier also removes comments from JSON. While the authors of php-json-minify and JSON.minify do not encourage the use of comments in JSON, they are glad to provide you a way to remove those comments anyway!
<?php
require_once(dirname(__FILE__) . '/src/t1st3/JSONMin/JSONMin.php');
use t1st3\JSONMin\JSONMin as jsonMin;
// Use static method
$a = jsonMin::minify('{"a": "b"}');
echo $a;
// get the minified JSON in a string
$b = new jsonMin('{"c": "d"}');
echo $b->getMin();
// prints the minifed JSON
$c = new jsonMin('{"e": "f"}');
$b->printMin();
?>
In order to build your generated Composer project from its source, you will need Grunt and PHP on the command line.
So, you must install PHP 5.6 on your system. Test it on your command line:
php --help
Note that the extension ext-dom is required by dev-dependencies. On Debian/Ubuntu, this extension is shipped by default with regular PHP installation. On Fedora/CentOS, you'll have to install the extension separately (yum install php-xml).
To install Grunt globally on the command line (and run the above build task), run:
npm install -g grunt-cli
Then, with Grunt, you can install Composer. Just run once:
grunt init
Then, you can install require-dev dependencies (PhpDocumentor, PhpUnit and PhpCPD) locally. Just run once:
php composer.phar install -v
Finally, you should also install the PHP extension named Xdebug, which will be used by PhpUnit for code coverage.
Once all your dependencies are installed, you can build your project with Grunt:
grunt build
The build process will run the following tasks:
- PhpLint: runs php -l over the "src" folder
- Runs the tests located in the "tests" folder with PHPUnit
- Generates a PhpDocumentor documentation in the "doc" folder from the files of the "src" folder
- Detects copy/paste of code in the files of the "src" folder with PhpCPD
php-json-minify was initiated with generator-composer, a Yeoman generator that builds a PHP Composer project.
