function - PHP Laravel use helper class in all views

I would like to create a helper (function) to avoid repeating code between all views in Laravel 5. The function should be using data from the database (Eloquent), so it cannot be just a simple function or a generic view composer.

Ideally it should be something like:

{!! Helper::addLinks($text) !!}

Where the Helper class uses Eloquent to validate the $value. I would like to avoid changing all Controllers. What is the best practice for this?

Update; I have the following working prototype. This function searches the text and replaces words found from the dictionary with hyperlinks:

function addLinks($text) {
    //retrieve words from database

    $words = Words::all();

    //build dictionary with values that needs replacement
    $patterns = array();
    foreach ($words as $word) {
        $patterns[$word->id] = $word->word_name;
    }

    //build dictionary with values the replacements
    $replacements = array();

    foreach ($words as $word) {
        $replacements[$word->id] = "id . "\">" . $patterns[$word->id] . "";
    }

    //return text, replace words from dictionary with hyperlinks
    return str_replace($patterns, $replacements, $text);
}

I want to use this function in several text blocks and paragraphs in the views. What approach is best?
