Get font name from Google Fonts URL with regular expression
<p>Please tell me how to <code>preg_match</code> font names from the Google Fonts URL.</p>

<p>For example, I want to extract the font name from:</p>

<pre><code>http://fonts.googleapis.com/css?family=Oswald:400,300
http://fonts.googleapis.com/css?family=Roboto+Slab
</code></pre>

<p>in order to get the font names <code>Oswald</code> and <code>Roboto Slab</code>.</p>
