HTML Pretty-Min
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().
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
