How do I update a MySQL table each time a page loads?
<?php include_once $_SERVER['DOCUMENT_ROOT'] . "/incl_func/env_constants.php"; ?>
    <?php
    //check 404 visits
    $ip = $_SERVER['REMOTE_ADDR'];
    $date = date("Y-m-d H:i:s");
    $agent = $_SERVER['HTTP_USER_AGENT'];
    $refer = $_SERVER['HTTP_REFERER'];

    $query = @mysql_query("INSERT INTO 404 (REF_URL, IP, AGENT, DATE) VALUES ('$refer', '$ip', '$agent', '$date')");
    ?>
