How to Convert HTML to Plain Text in PHP

The Hypertext PHP package converts HTML to pure text and beautifully handles various and malformed HTML. It works by taking an HTML string as input and removing all the markup, leaving the plain text:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>My Blog</title>
</head>
<body>
    <h1>Welcome to My Blog</h1>
    <p>This is a paragraph of text on my webpage.</p>
    <a href="https://blog.com/posts">Click here</a> to view my posts.
</body>
</html>

Using Hypertext's Transformer class, you can convert the HTML to pure text like so:

use Stevebauman\Hypertext\Transformer;
 
// Pure text output
echo (new Transformer)->toText($input);
 
// Welcome to My Blog This is a paragraph of text on my webpage. Click here to view my posts.

Let's say that you want to convert everything to text but also preserve newlines and links:

echo (new Transformer)
    ->keepLinks()
    ->keepNewLines()
    ->toText($input);
 
/*
Welcome to My Blog
This is a paragraph of text on my webpage.
<a href="https://blog.com/posts">Click Here</a> to view my posts.
