title: How to multiply $variable that includes € with a value
body: <p>since I'm new to PHP I have a quite simple question. After Googling and searching here on stackoverflow I still can't get it to work.</p>
  
  <pre><code>&lt;?php 
      $payinfront = $product-&gt;get_price_html();
      $totalprice = $payinfront * 2;
  ?&gt;
  
  &lt;p class="price"&gt;Total price: &lt;?php echo $totalprice ?&gt;&lt;/p&gt;
  &lt;p class="price"&gt;Amount to pay in front: &lt;?php echo $payinfront ?&gt;&lt;/p&gt;
  &lt;p class="price"&gt;Amount to pay after: &lt;?php echo $totalprice - $payinfront ?&gt;&lt;/p&gt;
  </code></pre>
  
  <p>The $payinfront value does get it's value from another part of my template. Let's say it's €10,-. This is the amount people have to pay in front. When we have done the service they have to pay the other half wich is the last rule.</p>
  
  <p>Thanks for helping me out!</p>
