PHP-Textile is a modern Textile markup language parser for PHP. Textile is a humane web text generator that takes lightweight, readable, plaintext-like markup language and converts it into well formed HTML.

Install

Using Composer:

$ composer require netcarver/textile

Usage

The Textile parser can be accessed through the Netcarver\Textile\Parser class. The class is highly configurable, and actual parsing happens with the parse method:

require './vendor/autoload.php';
$parser = new \Netcarver\Textile\Parser();
echo $parser->parse('h1. Hello World!');

Parsing untrusted input

If you are using PHP-Textile to format user-supplied input, blog comments for instance, remember to enable restricted parser mode:

$parser = new \Netcarver\Textile\Parser();
echo $parser
    ->setRestricted(true)
    ->parse('!bad/image/not/allowed.svg!');

In restricted mode PHP-Textile doesn’t allow more powerful formatting options such as inline styles, and removes any raw HTML.

Parsing single-line fields

If you are using PHP-Textile as a field-level formatter to parse just inline spans and glyphs, use the setBlockTags method to disable block tags:

$parser = new \Netcarving\Textile\Parser();
echo $parser
    ->setBlockTags(false)
    ->parse('Hello *strong* world!');

The above outputs:

Hello <strong>strong</strong> world!

Doctypes

Currently, PHP-Textile can target either XHTML or HTML5 output with XHTML being the default for backward compatibility. The targeted doctype can be changed via the setDocumentType method:

$parser = new \Netcarver\Textile\Parser();
echo $parser
    ->setDocumentType('html5')
    ->parse('HTML(HyperText Markup Language)');

Setting alternate glyphs

Textile’s typographic substitutions can be overridden with the setSymbol method. If you need to setup Textile to do non-standard substitutions, call setSymbol before you parse the input with parse.

$parser = new \Netcarver\Textile\Parser();
$parser
    ->setSymbol('half', '1⁄2')
    ->parse('Hello [1/2] World!');

The symbol names you can pass to setSymbol can be found here.

Prefixing relative image and link paths

Setting prefix might be useful if you want to point relative paths to certain consistent location:

$parser = new \Netcarver\Textile\Parser();
$parser
    ->setImagePrefix('/user/uploads')
    ->setLinkPrefix('/')
    ->parse('!image.jpg! "link":page');
