PHP library to handle truncate action on HTML strings

Features

• Truncates an HTML string keeping consistency on open/close tags
• No external dependencies.
• PSR-4 compatible.
• Compatible with PHP >= 5.3.3 and
• Integrations for Symfony2 and Twig.

Installation

You can install urodoz/truncateHTML through Composer:

$ composer require urodoz/truncate-html:@stable

Usage

Truncate an HTML string:

use Urodoz\Truncate\TruncateService;

$truncateService = new TruncateService();
echo $truncateService->truncate($htmlString, 100); //Truncating to 100 characters

Integrations

Symfony2

TruncateHTML contains a Symfony2 bundle and service definition that allow you to use it as a service in your Symfony2 application. The code resides in the Urodoz\Truncate\Bridge\Symfony namespace and you only need to add the bundle class to your AppKernel.php:

# app/AppKernel.php

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            // ...
            new Urodoz\Truncate\Bridge\Symfony\UrodozTruncateBundle(),
        );
        // ...
    }

    // ...
}

You can now use the urodoz_truncate service everywhere in your application, for example, in your controller:

$truncatedString = $this->get('urodoz_truncate')->truncate($htmlString, 100);

Twig

If you use the Symfony2 framework with Twig you can use the Twig filter truncateHTML in your templates after you have setup Symfony2 integrations (see above).

{{ truncateHTML(content, 250) }}

If you use Twig outside of the Symfony2 framework you first need to add the extension to your environment:

use Urodoz\Truncate\Bridge\Twig\TruncateExtension;
use Urodoz\Truncate\TruncateService;

$twig = new Twig_Environment($loader);
$twig->addFunction(new TruncateExtension(TruncateService::create()));

You can find more information about registering extensions in the Twig documentation.
