title: php if statement html option value
body: <p>Suppose you have the following html select statement</p>
  
  <pre><code>&lt;select&gt;
  &lt;option value="Newest"&gt;Newest&lt;/option&gt;
  &lt;option value="Best Sellers"&gt;Best Sellers&lt;/option&gt;
  &lt;option value="Alphabetical"&gt;Alphabetical&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>Now I want to run a php if elseif statement that says,</p>
  
  <pre><code>if (option value = newest) {
  // Run this
  }
  elseif ( option value = best sellers ) {
  // Run this
  }
  </code></pre>
  
  <p>etc.  But I don't know what to put inside the if elseif statement.  In other words instead of 'option value = newest' (which I know is incorrect), what can I put there so that if newest is selected it will execute the if statement, or if best sellers is selected it will execute the elseif statement?</p>
