title: Getting input values into php variables
body: <p>Is there any method to take value of the input to a php variable.</p>
  
  <pre><code>&lt;input type="text" name="s_amount" style='width:20%;' required&gt;
  </code></pre>
  
  <p>I want value of this s_amount to take into a php variable $s_amount.  This code is already inside a form. I want this conversion happen before submitting the form.</p>
