HTML minifier and indenter that works on the DOM tree

README 文档

README

HTML Pretty-Min is a PHP library for minifying and prettyprinting (indenting) HTML documents that works directly on the DOM tree of an HTML document.

Currently, it has the following features:

Prettyprint:
- Indent Block-level elements, do not indent inline elements
Minify:
- Remove whitespace and newlines
- Compress embedded Javascript using mrclay/jsmin-php
- Compress embedded CSS using tubalmartin/cssmin
- Remove some attributes when their value is empty (by default "style" and "class" attributes)
- Remove comments, except those matching some given regular expressions (by default, IE conditional comments are kept)

Installation

HTML Pretty-Min is listed on Packagist.

composer require wa72/html-pretty-min

Usage

<?php
use Wa72\HtmlPrettymin\PrettyMin;

$pm = new PrettyMin();

$output = $pm
    ->load($html)   // $html may be a \DOMDocument, a string containing an HTML code, 
                    // or an \SplFileInfo pointing to an HTML document
    ->minify()
    ->saveHtml();

For prettyprinting, call the indent() method instead of minify().

The PrettyMin() constructor can be given an associative options array. Here are the possible option keys and their default values:

    'minify_js' => true,
    'minify_css' => true,
    'remove_comments' => true,
    'remove_comments_exeptions' => ['/^\[if /'],
    'keep_whitespace_around' => [
        // keep whitespace around all inline elements
        'b', 'big', 'i', 'small', 'tt',
        'abbr', 'acronym', 'cite', 'code', 'dfn', 'em', 'kbd', 'strong', 'samp', 'var',
        'a', 'bdo', 'br', 'img', 'map', 'object', 'q', 'span', 'sub', 'sup',
        'button', 'input', 'label', 'select', 'textarea'
    ],
    'keep_whitespace_in' => ['script', 'style', 'pre'],
    'remove_empty_attributes' => ['style', 'class'],
    'indent_characters' => "\t"

Attention: Because the formatting is done directly on the DOM tree, a DOMDocument object given to the load() method will be modified:

$dom_document = new \DOMDocument('1.0', 'UTF-8');
$dom_document->loadHTML('<html>...some html code...</html>');

$pm->load($dom_document)->minify();

echo $dom_document->saveHTML(); // Will output the minified, not the original, document
