title: How to check a css file is minified or not using php
body: <p>I am creating an SEO analyzer that will check whether a CSS and js file is minified or not. An HTML parser will extract URL's of CSS and js files from a website. </p>
  
  <p>How can I check whether that CSS/js file is minified or not using PHP?</p>
  
  <p>CSS file's URL can be like this:</p>
  
  <pre><code>http://fonts.googleapis.com/css?family=Dosis:200,300,400,500,600,700,800
  http://www.inforge.in/css/style.css
  </code></pre>
