This is a list of HTML elements and their attributes generated from the HTML Living Standard.

Installation

composer require lnear/html

Usage

The functions are named after the HTML elements, and they take the attributes as named arguments. There are two flavours of functions each with their own namespaces: html and html\\strict.

The html\\strict namespace only allows attributes that are valid for the element according to the HTML Living Standard.

The html namespace is more permissive and allows any attribute to be passed to the function. The custom attribute names should be camelCase when called with the html namespace.

For example:

html\\strict\\a(href: 'https://example.com', dataFoo: 'bar'); // Throws an InvalidArgumentException

html\\a(href: 'https://example.com', dataFoo: 'bar'); // <a href="https://example.com" data-foo="bar"></a>

Other than that, the two namespaces are identical. The following examples use the html namespace, but you can use the html\\strict namespace if you want to enforce the HTML standard.

use html\\a;

echo a(href: 'https://example.com', target: '_blank', rel: 'noopener noreferrer'); // <a href="https://example.com" target="_blank" rel="noopener noreferrer"></a>

All functions return a Stringable class (html\\RenderResult) of the HTML element that it is named after. The only exception is the var function, which is named variable to avoid conflicts with the reserved keyword var.

The body argument is present in all non-self-closing elements. It is used to add text or other elements inside the element.

use html\\div;

echo div(body: 'Hello, World!'); // <div>Hello, World!</div>

It is also the first argument in those functions, so you can omit the argument name.

use html\\div;

echo div('Hello, World!'); // <div>Hello, World!</div>

More complex elements can be created by nesting functions, and the body argument can be an array of elements.

use html\\{div, a, p};

echo div(
    class: 'container',
    body: [
        a('Click me!', href: 'https://example.com', target: '_blank', rel: 'noopener noreferrer'),
        p('This is a paragraph.')
    ]
);

// <div class="container"><a href="https://example.com" target="_blank" rel="noopener noreferrer">Click me!</a><p>This is a paragraph.</p></div>

Encoding

The html\\RenderResult class implements the Stringable interface, so you can use it in any context where a string is expected. You can also use it to bypass the HTML encoding of a string.

use html\\{div, RenderResult};

$unsafe = '<script>alert("XSS")</script>';

echo div(body: $unsafe); // Default encoding: &lt;script&gt;alert(&quot;XSS&quot;)&lt;/script&gt;

$safe = RenderResult::wrap($unsafe); // Explicit encoding

echo div(body: $safe); // No double encoding: <div>&lt;script&gt;alert(&quot;XSS&quot;)&lt;/script&gt;</div>

$byPass = RenderResult::encoded($unsafe); // String already encoded

echo div(body: $byPass); // <div><script>alert("XSS")</script></div>
