title: Adding a dollar sign inside php
body: <p>I'm getting data from a database and inserting it into this table. 
   
  
  <pre><code>while (($result_row = $result-&gt;fetch_assoc()) !== NULL) {
      echo "&lt;tr&gt;";
      echo "&lt;td&gt;", $result_row['title'], "&lt;/td&gt;";
      echo "&lt;td&gt;", $result_row['author'], "&lt;/td&gt;";
      echo "&lt;td&gt;", $result_row['isbn'], "&lt;/td&gt;";
  
      echo  "&lt;td&gt;", $result_row['price'], "&lt;/td&gt;";
  
      echo "&lt;/tr&gt;";
  }
  </code></pre>
  
  <p>I can't seem to figure out how to print an actual $ for the price.  Any suggestions?</p>
