If you want some internal linking optimization, you can obfuscate links with this library.

📦 How to install this project ?

composer require fantassin/shadow
npm install @fantassin/shadow

⚡ How it works ?

To generate obfuscate links you can use standalone Shadow class like this in your PHP file :

<?php

use Fantassin\Shadow\Shadow;

$shadow = new Shadow();
// Get encoded version of link.
$shadow->encode( 'https://www.fantassin.fr' ); // dWdnY2Y6Ly9qamouc25hZ25mZnZhLnNl

// Or you can get attributes generated automatically
echo '<span ' . $shadow->get_attributes( 'https://www.fantassin.fr' ) . '>Your anchor link</span>';

// And you will get :
// <span data-shdw="dWdnY2Y6Ly9qamouc25hZ25mZnZhLnNl">Your anchor link</span>

🎯 Advanced usage

1. Customize attributes

<?php

use Fantassin\Shadow\Shadow;

$shadow = new Shadow( 'your-attribute' );
// Get customize attributes
echo '<span ' . $shadow->get_attributes( 'https://www.fantassin.fr' ) . '>Your anchor link</span>';

// And you will get :
// <span your-attribute="dWdnY2Y6Ly9qamouc25hZ25mZnZhLnNl">Your anchor link</span>

2. Use target attribute

<?php

use Fantassin\Shadow\Shadow;

$shadow = new Shadow();
// Or you can get attributes generated automatically
echo '<span ' . $shadow->get_attributes( 'https://www.fantassin.fr', '_blank' ) . '>Your anchor link</span>';

// And you will get :
// <span data-shdw="dWdnY2Y6Ly9qamouc25hZ25mZnZhLnNl" data-shadow-target="_blank">Your anchor link</span>

$shadow = new Shadow( 'your-attribute' );
// Get customize attributes
echo '<span ' . $shadow->get_attributes( 'https://www.fantassin.fr', '_blank' ) . '>Your anchor link</span>';

// And you will get :
// <span your-attribute="dWdnY2Y6Ly9qamouc25hZ25mZnZhLnNl" your-attribute-target="_blank">Your anchor link</span>
