README

A comprehensive PHP library for programmatically building HTML. Covers essentially all of HTML5.

Installation

composer require joby/html-object-strings

Usage

Tags live in the Joby\HTML\Html5 namespace. Find the tag class you need, instantiate it, and use the fluent setters to configure it. Every attribute and behavior is documented in the class and method docblocks, sourced from MDN.

use Joby\HTML\Html5\InlineTextSemantics\ATag;
use Joby\HTML\Html5\TextContentTags\DivTag;
use Joby\HTML\Nodes\Text;

$div = new DivTag();
$div->addChild(
    (new ATag())
        ->setHref('https://example.com')
        ->addChild(new Text('Click here'))
);

echo $div;

Parsing

HTML can be parsed back into the object model using Html5Parser. This feature is still somewhat experimental.

use Joby\HTML\Html5\Html5Parser;

$parser = new Html5Parser();

// Parse a fragment into a container of nodes
$fragment = $parser->parseFragment('<div id="foo"><p>Hello</p></div>');

// Parse a full document
$document = $parser->parseDocument('<html><head><title>My Page</title></head><body><div>foo</div></body></html>');
echo $document->html()->head()->title()->content(); // "My Page"

Unknown tags and whitespace-only text nodes are silently dropped. Parsed nodes are full objects — attributes, classes, and styles are all accessible and mutable.

The parser is extensible: subclass AbstractParser or Html5Parser and configure $tag_namespaces and $tag_classes to support custom tag sets.

Traversal

Any container — parsed or built programmatically — can be walked recursively using walk(). It yields all descendant nodes depth-first, optionally filtered by class:

use Joby\HTML\Html5\InlineTextSemantics\ATag;

// Find all links in a parsed fragment and rewrite their hrefs
foreach ($fragment->walk(ATag::class) as $link) {
    $link->setHref('https://proxy.example.com?url=' . urlencode($link->href()));
}

// Walk all nodes without filtering
foreach ($fragment->walk() as $node) {
    echo get_class($node) . PHP_EOL;
}

Requirements

Fully tested on PHP 8.3+, static analysis for PHP 8.1.
