Estimated Reading Time using Laravel Macro

If you are building an information system that shares text-based content, you may need to add an estimated reading time for that content. Some time ago, Marcel Pociot shared a code snippet for the helper using macro in Laravel.

Here's a nice little string helper macro for @laravelphp , that gives you the estimated reading time for the given text(s).

The estimated reading time can help the reader estimate how long the user can read the content to completion.

And here is the code snippet.

Str::macro('readDuration', function(...$body) {
    $totalWords = str_word_count(implode(" ", $body));
    $minutesToRead = round($totalWords / 200);

    return (int)max(1, $minutesToRead);
});

$est = Str::readDuration($post->body). ' min read';
