title: Add X Days To Date, Excluding Weekends
body: <p>I'm currently developing an online subscription application. I'm having some challenges on the part where the user will select the Number of Days to subscribe and then the Start Date. The PHP application should then be able to calculate the End Date excluding weekends.</p>
  
  <pre><code>&lt;form method="post"&gt;
      &lt;input name="startdate" type="text" /&gt;
      &lt;input name="numberofdays" type="text" /&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>Someone can help me with this?</p>
