Hello,
PHP filters are used to validate and sanitize external input.

The PHP filter extension has many of the functions needed for checking user input, and is designed to make data validation easier and quicker.

<table>
  <tr>
    <td>Filter Name</td>
    <td>Filter ID</td>
  </tr>
  <?php
  foreach (filter_list() as $id =>$filter) {
      echo '<tr><td>' . $filter . '</td><td>' . filter_id($filter) . '</td></tr>';
  }
  ?>
</table>

Many web applications receive external input. External input/data can be:

User input from a form
Cookies
Web services data
Server variables
Database query results

I have a question about using a php user class and session variables. Let's say that I have managed to create a user class that finds a particular person from the database query.

As I move about the site from page to page it would be nice to be able to use the current user inside the user class without needing to re – look them up in the database multiple times

Q: so is there a way to combine the current active user in the class with session variables so that they can be used multiple times? If so, how would this work?
