php-latex

The main purpose of this library is to provide a valid LaTeX output from, not always valid, user input. You can also render LaTeX code to HTML, with one limitation though - rendering to HTML is done only for the text mode, the math mode needs to be handled by a JavaScript library - in the browser. For this I recommend using MathJax.

Installation

To use php-latex, you install it just as any other php package - with Composer.

composer require xemlock/php-latex:dev-master

Usage

Basic usage is as follows:

Parsing LaTeX source code:

$parser = new PhpLatex_Parser();
$parsedTree = $this->parse($input);
// $parsedTree contains object representation of the LaTeX document

Once you have a parsed source code, you can render it to HTML (or to LaTeX) - please mind that math-mode code is rendered as-is.

// render parsed LaTeX code to HTML
$htmlRenderer = new PhpLatex_Renderer_Html();
$html = $htmlRenderer->render($parsedTree);

// render parsed LaTeX code to sanitized LaTeX code
$latex = PhpLatex_Renderer_Abstract::toLatex($parsedTree);

You can also add custom (or not yet implemented) commands to the parser:

$parser = new PhpLatex_Parser();
$parser->addCommand(
    '\placeholder',
    array(
        // number of arguments
        'numArgs' => 1,
        // number of optional arguments, default 0
        'numOptArgs' => 1,
        // mode this command is valid in, can be: 'both', 'math', 'text'
        'mode' => 'both',
        // whether command arguments should be parsed, or handled as-is
        'parseArgs' => false,
        // whether command allows a starred variant
        'starred' => false,
    )
);
