• Install via composer composer require -dev dbx123/php-minifier

Using PHPMin

How to compress HTML:, _(*5)

$minified_html = PHPMin\Minify::html($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., _(*6)

How to compress CSS:, _(*7)

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

How to compress JS:, _(*8)

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

Spelling out out:, _(*9)

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!!
