PHP wrapper to execute less node package or fallback to a PHP alternative.

Usage

First you need composer if you have not already. Then get the package with composer require nodejs-php-fallback/less then require the composer autload in your PHP file if it's not already:

<?php

use NodejsPhpFallback\Less;

// Require the composer autoload in your PHP file if it's not already.
// You do not need to if you use a framework with composer like Symfony, Laravel, etc.
require 'vendor/autoload.php';

$less = new Less('path/to/my-less-file.less');

// Output to a file:
$less->write('path/to/my-css-file.css');

// Get CSS contents:
$cssContents = $less->getResult();

// Output to the browser:
header('Content-type: text/css');
echo $less;

// You can also get less code from a string:
$less = new Less('
a {
 color: blue;
 &:hover {
 color: navy;
 }
}
');
// Then write CSS with:
$less->write('path/to/my-css-file.css');
// or get it with:
$cssContents = $less->getResult();

// Pass true to the less constructor to minify the rendered CSS:
$less = new Less('path/to/my-less-file.styl', true);
