phpmin-php-minifier

PHPMin is an inline PHP minifier for web resources. It lets you minify HTML4, HTML5, XHTML, CSS and JavaScript files in a single line of code.

The best bit is its free and open source under the BSD license.

Installing PHPMin

Installing PHPMin should only take a minute. Here are your choices:

• Install via composer composer require -dev dbx123/php-minifier
• Hit the 'Download Zip' button on GitHub. https://github.com/dbx123/php-minifier

You can include all the necessary classes by simply including the php-minifier/phpmin.php file.

require_once ("php-minifier/phpmin.php");

Using PHPMin

How to compress HTML:

$minified_html = PHPMin\Minify::html($any_html);

This automatically compresses all inline scripts and stylesheets within the HTML document. Apply a 'data-no-min' attribute to a script or style in your HTML markup to exclude it from minification.

How to compress CSS:

$minified_css = PHPMin\Minify::css($any_css);

How to compress JS:

$minified_js = PHPMin\Minify::js($any_js);

Spelling out out:

require_once ("php-minifier/phpmin.php");

$html = file_get_contents("http://en.wikipedia.org/wiki/Minification_%28programming%29");
$minified_html = PHPMin\Minify::html($html);
// a 9.38% performance boost - in 3 lines of code!!

There are working examples in the /examples folder of the package.

PHPMin Performance

• The compression ratio are typically 5-20% for HTML
• The compression ratio are typically 5-30% for CSS
• The compression ratio are typically 5-30% for JavaScript

Even highly optimized sites such as wikipedia.com, github.com and W3Schools.com could reduce the size of their HTML payload using PHPMin html compression.

PHPMin Improvements

• We are relatively new to Composer - and welcome input on package improvements.
• Removing default values from html tags should reduce HTML file size
• Allowing HTML fragments rather than whole documents would be ideal.
