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.
Bear in mind that not every LaTeX command is recognized or implemented. If you happen to need a command that's not supported you can either define it manually (see description below), or file a feature request.
To use php-latex, you install it just as any other php package - with Composer.
composer require xemlock/php-latex:dev-master
Basic usage is as follows:
$parser = new PhpLatex_Parser();
$parsedTree = $parser->parse($input);
// $parsedTree contains object representation of the LaTeX documentOnce 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 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,
)
);Additionally, this library provides a wrapper for pdflatex to make rendering and compiling .tex files
from PHP scripts easier.
$pdflatex = new PhpLatex_PdfLatex();
// to generate a PDF from .tex file
$pathToGeneratedPdf = $pdflatex->compile('/path/to/document.tex',
array(/* optional paths to files included by .tex file (images) */])
);You can access the build log of the last compile call via:
echo $pdflatex->getLog();You can even compile on the fly a LaTeX string:
$pathToGeneratedPdf = $pdflatex->compileString('
\documentclass{article}
\begin{document}
Hello from \LaTeX!
\end{document}
');By default, a system temp dir is used for generating PDF from string. You can however customize it:
$pdflatex->setBuildDir('/path/to/temp'); The MIT License (MIT). See the LICENSE file.
