 * For what it’s worth, WordPress requires PHP 5.2.4 as of WP 3.2 (released in July
   2011). `filter_var` has been available since PHP 5.2.0 so there’s really no need
   to check if it exists 🙂

 * Hey Spinal– thanks for the feedback. We added it in after receiving support requests–
   in the interest of backwards compatibility, we decided to put it in.
 * Best,
    Sam
