🗜️ 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"

composer require voku/html-min

Quick Start

use voku\helper\HtmlMin;

$html = "
<html>
  \r\n\t
  <body>
    <ul style=''>
      <li style='display: inline;' class='foo'>
        \xc3\xa0
      </li>
      <li class='foo' style='display: inline;'>
        \xc3\xa1
      </li>
    </ul>
  </body>
  \r\n\t
</html>
";
$htmlMin = new HtmlMin();

echo $htmlMin->minify($html); 
// '<html><body><ul><li class=foo style="display: inline;"> à <li class=foo style="display: inline;"> á </ul>'

Options

use voku\helper\HtmlMin;

$htmlMin = new HtmlMin();

/* 
 * Protected HTML (inline css / inline js / conditional comments) are still protected,
 *    no matter what settings you use.
 */

$htmlMin->doOptimizeViaHtmlDomParser();               // optimize html via "HtmlDomParser()"
$htmlMin->doRemoveComments();                         // remove default HTML comments (depends on "doOptimizeViaHtmlDomParser(true)")
$htmlMin->doSumUpWhitespace();                        // sum-up extra whitespace from the Dom (depends on "doOptimizeViaHtmlDomParser(true)")
$htmlMin->doRemoveWhitespaceAroundTags();             // remove whitespace around tags (depends on "doOptimizeViaHtmlDomParser(true)")
$htmlMin->doOptimizeAttributes();                     // optimize html attributes (depends on "doOptimizeViaHtmlDomParser(true)")
$htmlMin->doRemoveHttpPrefixFromAttributes();         // remove optional "http:"-prefix from attributes (depends on "doOptimizeAttributes(true)")
$htmlMin->doRemoveHttpsPrefixFromAttributes();        // remove optional "https:"-prefix from attributes (depends on "doOptimizeAttributes(true)")
$htmlMin->doKeepHttpAndHttpsPrefixOnExternalAttributes(); // keep "http:"- and "https:"-prefix for all external links 
$htmlMin->doMakeSameDomainsLinksRelative(['example.com']); // make some links relative, by removing the domain from attributes
$htmlMin->doRemoveDefaultAttributes();                // remove defaults (depends on "doOptimizeAttributes(true)" | disabled by default)
$htmlMin->doRemoveDeprecatedAnchorName();             // remove deprecated anchor-jump (depends on "doOptimizeAttributes(true)")
$htmlMin->doRemoveDeprecatedScriptCharsetAttribute(); // remove deprecated charset-attribute - the browser will use the charset from the HTTP-Header, anyway (depends on "doOptimizeAttributes(true)")
$htmlMin->doRemoveDeprecatedTypeFromScriptTag();      // remove deprecated script-mime-types (depends on "doOptimizeAttributes(true)")
$htmlMin->doRemoveDeprecatedTypeFromStylesheetLink(); // remove "type=text/css" for css links (depends on "doOptimizeAttributes(true)")
$htmlMin->doRemoveDeprecatedTypeFromStyleAndLinkTag(); // remove "type=text/css" from all links and styles
$htmlMin->doRemoveDefaultMediaTypeFromStyleAndLinkTag(); // remove "media="all" from all links and styles
$htmlMin->doRemoveDefaultTypeFromButton();            // remove type="submit" from button tags 
$htmlMin->doRemoveEmptyAttributes();                  // remove some empty attributes (depends on "doOptimizeAttributes(true)")
$htmlMin->doRemoveValueFromEmptyInput();              // remove 'value=""' from empty <input> (depends on "doOptimizeAttributes(true)")
$htmlMin->doSortCssClassNames();                      // sort css-class-names, for better gzip results (depends on "doOptimizeAttributes(true)")
$htmlMin->doSortHtmlAttributes();                     // sort html-attributes, for better gzip results (depends on "doOptimizeAttributes(true)")
$htmlMin->doRemoveSpacesBetweenTags();                // remove more (aggressive) spaces in the dom (disabled by default)
$htmlMin->doRemoveOmittedQuotes();                    // remove quotes e.g. class="lall" => class=lall
$htmlMin->doRemoveOmittedHtmlTags();                  // remove ommitted html tags e.g. <p>lall</p> => <p>lall

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