title: How could I make this PHP $_POST more secure? -Or is it secure already?
body: <p>On most my $_post data inputted on my site I use the following php:</p>
  
  <pre><code>$example = $_POST['textfield'];
  $example = strip_tags($example);
  $example = mysql_real_escape_string($example);
  </code></pre>
  
  <p>And then I would interact with the MySQL database...</p>
  
  <p>Is this 'secure' / 'safe'?</p>
  
  <p>Any major exploits to the above code?</p>
  
  <p>-How could I make it secure?</p>
