futape/html-utility

This library offers a set of utilities for working with HTML markup.

Utility functions are implemented as static functions in an abstract class, which is never expected to be instantiated.

Moreover this library offers a HtmlInliner and its subclass SemanticHtmlInliner (see below).

Install

composer require futape/html-utility

Usage

Html

This utility class offers functions for working with HTML markup.

use Futape\Utility\Html\Html;

echo Html::preformatted("PHP is <3\n Foo   Bar\nBaz\tBam ");
// "PHP is &lt;3<br />\n&nbsp;Foo &nbsp; Bar<br />\nBaz&nbsp;&nbsp;&nbsp;&nbsp;Bam&nbsp;"

HtmlInliner

A class for converting HTML markup to plaintext and inlining any text.

The following example is taken from the unit tests.

markup.html

<h1>A markup file</h1>
<p>This is just a file containing HTML markup.</p>
<table>
    <thead>
        <tr>
            <th>First Name</th>
            <th>Last Name</th>
            <th>Age</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>John</td>
            <td>Doe</td>
            <td>42</td>
        </tr>
    </tbody>
</table>
<p>A list of very important stuff:</p>
<ul>
    <li>One</li>
    <li>Two</li>
</ul>
<p>And a list of definitions:</p>
<dl>
    <dt>WWW</dt>
    <dd>World Wide Web</dd>
    
    <dt>HTTP</dt>
    <dd>Hypertext Transfer Protocol</dd>
</dl>
<img src="http://example.com/picture.jpg" alt="An example picture" />

inline.php

use Futape\Utility\Html\HtmlInliner;

echo (new HtmlInliner(file_get_contents('./markup.html')))->render();
// "A markup file This is just a file containing HTML markup. A list of very important stuff: One, Two, And a list of definitions: WWW: World Wide Web, HTTP: Hypertext Transfer Protocol,"

SemanticHtmlInliner

This is a subclass of the HtmlInliner and takes the semantic meaning of HTML elements into account instead of relying mostly on their display.

Testing

The library is tested by unit tests using PHP Unit.

To execute the tests, install the composer dependencies (including the dev-dependencies), switch into the tests directory and run the following command:

../vendor/bin/phpunit
