Html interop

Common interfaces and type-safe enums for HTML tag interoperability
Provides standardized contracts and tag collections for block, inline, list, root, table, and void elements.

Features

Installation

composer require ui-awesome/html-interop:^0.2

Quick start

Using block-level HTML tags

Access standardized block-level tag names through the Block enum.

<?php

declare(strict_types=1);

namespace App;

use UIAwesome\Html\Interop\Block;

echo Block::DIV->value;
// 'div'

echo Block::ARTICLE->value;
// 'article'

echo Block::SECTION->value;
// 'section'

Using inline-level HTML tags

Access standardized inline-level tag names through the Inline enum.

<?php

declare(strict_types=1);

namespace App;

use UIAwesome\Html\Interop\Inline;

echo Inline::SPAN->value;
// 'span'

echo Inline::STRONG->value;
// 'strong'

echo Inline::A->value;
// 'a'

Using void (self-closing) HTML tags

Access standardized void element tag names through the Voids enum.

<?php

declare(strict_types=1);

namespace App;

use UIAwesome\Html\Interop\Voids;

echo Voids::IMG->value;
// 'img'

echo Voids::INPUT->value;
// 'input'

echo Voids::BR->value;
// 'br'

Using specialized HTML tag collections

Use specialized enums for list, root, and table elements.

<?php

declare(strict_types=1);

namespace App;

use UIAwesome\Html\Interop\{Lists, Root, Table};

// List elements
echo Lists::UL->value;
// 'ul'

echo Lists::OL->value;
// 'ol'

echo Lists::LI->value;
// 'li'

// Root elements
echo Root::HTML->value;
// 'html'

echo Root::HEAD->value;
// 'head'

echo Root::BODY->value;
// 'body'

// Table elements
echo Table::TABLE->value;
// 'table'

echo Table::THEAD->value;
// 'thead'

echo Table::TR->value;
// 'tr'

echo Table::TD->value;
// 'td'

Type safety with interfaces

Use the provided interfaces to ensure type safety in your tag rendering implementations.

<?php

declare(strict_types=1);

namespace App;

use UIAwesome\Html\Interop\BlockInterface;

/**
 * Render HTML using any BlockInterface implementation.
 */
function renderBlock(BlockInterface $tag, string $content): string
{
    return sprintf('<%s>%s</%s>', $tag->value, $content, $tag->value);
}

echo renderBlock(Block::DIV, 'Content');
// <div>Content</div>

echo renderBlock(Block::ARTICLE, 'Article content');
// <article>Article content</article>

Filtering and iterating tags

Leverage PHP 8.1+ enum features for filtering and tag operations.

<?php

declare(strict_types=1);

namespace App;

use UIAwesome\Html\Interop\Block;

// Filter heading elements
$headings = array_filter(
    Block::cases(),
    fn (Block $tag) => str_starts_with($tag->name, 'H'),
);

foreach ($headings as $heading) {
    echo $heading->value . PHP_EOL;
}
// h1
// h2
// h3
// h4
// h5
// h6

// Get all block tag names
$tagNames = array_map(fn (Block $tag) => $tag->value, Block::cases());

Extensibility

Create custom tag collections by implementing the core interfaces backed by string enums.

• \UIAwesome\Html\Interop\BlockInterface: For container elements that have content and a closing tag.
• \UIAwesome\Html\Interop\InlineInterface: For text-level elements.
• \UIAwesome\Html\Interop\VoidInterface: For self-closing elements (no closing tag).

You can create custom enums for your specific domain (for example, SVG, MathML, or Web Components) and use them across multiple packages.

<?php

declare(strict_types=1);

namespace App;

use UIAwesome\Html\Interop\BlockInterface;

enum SvgTag: string implements BlockInterface
{
    case SVG = 'svg';
    case G = 'g';
    case PATH = 'path';
    // ... add other SVG block tags as needed
}

// Now you can use it with any BlockInterface-compatible renderer
function renderAnyBlock(BlockInterface $tag, string $content): string
{
    return "<{$tag->value}>$content</{$tag->value}>";
}

echo renderAnyBlock(SvgTag::G, '...');
// <g>...</g>
