Does it make sense to have a PHP class just for cleaning/escaping user input?
<p>My application persists a large amount of data into a MySql database, and I'm wondering if I should handle the cleaning/escaping with a separate class, or if this is overkill? Also, I'm using prepared statements with PDO, so I'm not exactly sure how much cleaning or escaping data I should be doing in combination with binding parameters.</p>

<p>I'm aware of the old Perl adage, "There's more than one way to do it," so I'm not asking for an actual solution. I'm just trying to weigh the benefits of calling in another class to handle the escaping, or if the simplicity of this process would better be handled locally.</p>
