Hi friends,is Pug-HTML helping you?
I need your HELP!!! I am surprised that last year I received only $3 from a good man to support. It is not enough, and I need you help to pay domain, hosting, and maintain fees of this service.


Pug, PHP
Feb 28, 2018
Pug-php adds inline PHP scripting support to the Pug template compiler. Since the version 3, it uses Phug, a very customizable Pug template engine made by Tale-pug and Pug-php developpers as the new PHP Pug engine reference.

First you need composer if you have'nt yet: https://getcomposer.org/download/

Then run:

composer require pug-php/pug

include 'vendor/autoload.php';

$pug = new Pug([
    // here you can set options


Since Pug-php 3.1.2, you no longer need to import the class with use Pug\Pug; as we provide an alias.

Main methods are render, renderFile, compile, compileFile, display, displayFile and setOption, see the complete documentation here: phug-lang.com.

You can also use the facade to call methods statically:


use Pug\Facade as PugFacade;

include 'vendor/autoload.php';

$html = PugFacade::renderFile('my-pug-template.pug');

Pug options

Pug options should be passed to the constructor

$pug = new Pug(array(
    'pretty' => true,
    'cache' => 'pathto/writable/cachefolder/'

Supports for local variables

$pug = new Pug();
$output = $pug->render('file', array(
    'title' => 'Hello World'

New in pug-php 3

pug-php 3 is now aligned on pugjs 2, it aims to be a perfect port of the JS project. That's why there are breaking changes in this new version.

See the changelog to know what's new

See the migration guide if you want to upgrade from pug-php 2 to 3

Supports for custom filters

Filters must be callable: It can be a class that implements the __invoke() method, or an anonymous function.

$pug->filter('escaped', 'My\Callable\Class');

// or

$pug->filter('escaped', function($node, $compiler){
    foreach ($node->block->nodes as $line) {
        $output[] = $compiler->interpolate($line->value);
    return htmlentities(implode("\n", $output));

Built-in filters

  • :css
  • :php
  • :javascript
  • :escaped
  • :cdata

Install other filters with composer


Publish your own filter


Supports for custom keywords

You can add custom keywords, here are some examples:

Anonymous function:

$pug->addKeyword('range', function ($args) {
    list($from, $to) = explode(' ', trim($args));

    return array(
        'beginPhp' => 'for ($i = ' . $from . '; $i <= ' . $to . '; $i++) {',
        'endPhp' => '}',

range 1 3
    p= i

This will render:


Note that the existing for..in operator will have the precedence on this custom for keyword.

Invokable class:

class UserKeyword
    public function __invoke($arguments, $block, $keyWord)
        $badges = array();
        foreach ($block->nodes as $index => $tag) {
            if ($tag->name === 'badge') {
                $href = $tag->getAttribute('color');
                $badges[] = $href['value'];

        return array(
            'begin' => '<div class="' . $keyWord . '" data-name="' . $arguments . '" data-badges="[' . implode(',', $badges) . ']">',
            'end' => '</div>',

$pug->addKeyword('user', new UserKeyword());

user Bob
    em Registered yesterday

This will render:

<div class="user" data-name="Bob" data-badges="['blue', 'red']">
    <em>Registered yesterday</em>

A keyword must return an array (containing begin and/or end entires) or a string (used as a begin entry).

The begin and end are rendered as raw HTML, but you can also use beginPhp and endPhp as in the first example to render PHP codes that will wrap the rendered block if there is one.

PHP Helpers functions

If you want to make a php function available in a template or in all of them for convenience, use closures ans pass them like any other variables:

$myClosure = function ($string) {
    return 'Hey you ' . $string . ', out there on your own, can you hear me?';

$pug->render('p=$myClosure("Pink")', array('myClosure' => $myClosure));

This will render:

<p>Hey you Pink, out there on your own, can you hear me?</p>

You can make that closure available to all templates without passing it in render params by using the share method:

// ... $pug instantiation
$pug->share('myClosure', $myClosure);

This will render the same HTML than the previous example. Also note that share allow you to pass any type of value.


Important: to improve performance in production, enable the Pug cache by setting the cache option to a writable directory, you can first cache all your template at once (during deployment):

$pug = new Pug(array(
    'cache' => 'var/cache/pug',
list($success, $errors) = $pug->cacheDirectory('path/to/pug/templates');
echo "$success files have been cached\n";
echo "$errors errors occurred\n";

Be sure any unexpected error occurred and that all your templates in your template directory have been cached.

Then use the same cache directory and template directory in production with the option upToDateCheck to false to bypass the cache check and automatically use the cache version:

$pug = new Pug(array(
    'cache' => 'var/cache/pug',
    'basedir' => 'path/to/pug/templates',
    'upToDateCheck' => false,

Templates from pug-js

First remember pug-php is a PHP template engine. Pug-js and Pug-php provide both a HAML-like syntax for markup, but for expression and raw code, pug-js use JS, and pug-php use PHP. By default, we did some magic tricks to transform simple JS syntaxes into PHP. This should help you to migrate smoother from pug-js if you already have some template but benefit of PHP advantages.

If you start a new project, we highly recommend you to use the following option:

$pug = new Pug(array(
    'expressionLanguage' => 'php'

It will disable all translations, so you have to use always explicit PHP syntaxes such as:

- $concat = $foo . $bar

If you want expressions closest to JS, you can use:

$pug = new Pug(array(
    'expressionLanguage' => 'js'

It will allow both PHP stuff and JS stuff in a JS-style syntax. But you must stick to it, you will not be able to mix PHP and JS styles in this mode.

Finally, you can use the native pug-js engine with:

$pug = new Pug(array(
    'pugjs' => true

This mode require node and npm installed as it will install pug-cli and directly call it. This mode will flat you local vars (it means complex object like DateTime, or classes with magic methods will be striginfied in JSON as simple objects) and you will not benefit some features like mixed indent, pre/post render hooks but in this mode you will get exact same output as in pug-js.

Write locals object to json file with pugjs

If your locals object is large it may cause a RuntimeException error. This is because locals object passed directly to pug-cli as argument. To fix this problem you can use localsJsonFile option:

$pug = new Pug(array(
    'pugjs' => true,
    'localsJsonFile' => true

Then your locals will be written to json file and path to file will be passed to compiler.


Pug also provide a CLI tool:

./vendor/bin/pug render-file dir/my-template.pug --output-file 

See the complete CLI documentation here

Check requirements

To check if all requirements are ready to use Pug, use the requirements method:

$pug = new Pug(array(
    'cache' => 'pathto/writable/cachefolder/'
$missingRequirements = array_keys(array_filter($pug->requirements(), function ($valid) {
    return $valid === false;
$missings = count($missingRequirements);
if ($missings) {
    echo $missings . ' requirements are missing.<br />';
    foreach ($missingRequirements as $requirement) {
        switch($requirement) {
            case 'streamWhiteListed':
                echo 'Suhosin is enabled and ' . $pug->getOption('stream') . ' is not in suhosin.executor.include.whitelist, please add it to your php.ini file.<br />';
            case 'cacheFolderExists':
                echo 'The cache folder does not exists, please enter in a command line : <code>mkdir -p ' . $pug->getOption('cache') . '</code>.<br />';
            case 'cacheFolderIsWritable':
                echo 'The cache folder is not writable, please enter in a command line : <code>chmod -R +w ' . $pug->getOption('cache') . '</code>.<br />';
                echo $requirement . ' is false.<br />';
