如何自动更新网页的URI？

Question

我有一个名为files的表，其中有id、名称、网页、访问者等列。表中已有文件列表。现在，我已经创建了名为webpage和visitors的新列。网页是文件的URI，访问者是文件的计数器视图。问题是我想用session自动更新网页和访客，但我不能。你能帮我吗？

<?php

session_start();

include_once"config.php";

$webpage=htmlspecialchars($_SERVER["REQUEST_URI"]);


$result=mysql_query("SELECT * FROM files WHERE webpage='$webpage'");
$num_rows = mysql_num_rows($result);
if ($num_rows == 0){
mysql_query("How to update the URI ($webpage) automatically? in the files table inside the column webpage");

}else{

if (!isset($_SESSION['webpage'])){$_SESSION['webpage'] = 0;
mysql_query("UPDATE files SET visitors=visitors+1 WHERE webpage='$webpage'");}}

?>

尝试此解决方案：

<?php

session_start();

include_once"config.php";

$webpage=htmlspecialchars($_SERVER["REQUEST_URI"]);


$result=mysql_query("SELECT * FROM files WHERE webpage='$webpage'");
$num_rows = mysql_num_rows($result);
if ($num_rows == 0)
{
    $_SESSION['webpage'][] = $webpage;
    mysql_query("INSERT INTO files (`id`,`name`,`webpage`,`visitors`) VALUES (null,'$name','$webpage','1')");
}
else
{
    if(is_array($_SESSION['webpage'])) && !in_array($webpage, $_SESSION['webpage'])))
    {
        $_SESSION['webpage'][] = $webpage;
        mysql_query("UPDATE files SET visitors=visitors+1 WHERE webpage='$webpage'");
    }
}
?>
