:clamp: HtmlMin: HTML Compressor and Minifier for PHP

Description

HtmlMin is a fast and very easy to use PHP library that minifies given HTML5 source by removing extra whitespaces, comments and other unneeded characters without breaking the content structure. As a result pages become smaller in size and load faster. It will also prepare the HTML for better gzip results, by re-ranging (sort alphabetical) attributes and css-class-names.

Install via "composer require"

Quick Start

Options

Current optional tag support from the WHATWG HTML syntax rules:

• <html>: start tag may be omitted when the first child is not a comment; end tag may be omitted when the element is not immediately followed by a comment.
• <head>: start tag may be omitted when the element is empty or starts with an element; end tag may be omitted when it is not immediately followed by ASCII whitespace or a comment.
• <body>: start tag may be omitted when the element is empty or starts with something other than ASCII whitespace / a comment / meta / noscript / link / script / style / template; end tag may be omitted when it is not immediately followed by a comment.
• <p>: end tag may be omitted before address, article, aside, blockquote, details, dialog, div, dl, fieldset, figcaption, figure, footer, form, h1-h6, header, hgroup, hr, main, menu, nav, ol, p, pre, search, section, table, or ul, or at the end of the parent when the parent is not a, audio, del, ins, map, noscript, video, or an autonomous custom element.
• <li>, <dt>, <dd>, <rt>, <rp>, <tr>, <td>, and <th>: the end tag may be omitted in the standard adjacent-sibling / end-of-parent cases from the spec.
• <option>: the end tag may be omitted before another option, optgroup, or hr, or at the end of the parent.
• <optgroup>: the end tag may be omitted before another optgroup or hr, or at the end of the parent.
• <colgroup>: the start tag may be omitted when the first child is col and the previous omitted-tag rule does not block it; the end tag may be omitted when it is not immediately followed by ASCII whitespace or a comment.
• <caption>: the end tag may be omitted when it is not immediately followed by ASCII whitespace or a comment.
• <thead>: the end tag may be omitted before tbody or tfoot.
• <tbody>: the start tag may be omitted when the first child is tr and the previous omitted-tag rule does not block it; the end tag may be omitted before tbody / tfoot or at the end of the parent.
• <tfoot>: the end tag may be omitted at the end of the parent.

Start tags are never omitted when the element has attributes.

PS: you can use the "nocompress"-tag to keep the html e.g.: "\n foobar \n"
