<?php

if($_COOKIE["user"]["xm"] <> "")
$visnum = intval($_COOKIE["user"]["num"])+1;
setcookie("user[num]" , $visnum , time()+3600);
setcookie("user[dt]" , date("Y-m-d h:i:s") ,time()+3600);
echo "welcome " . $_COOKIE["user"]["xm"];
echo "<br />This is your " . $visnum . " th" . " visit my website";
echo "<br />The latest visit time is " .$_COOKIE["user"]["dt"] ;
else
echo
'<html><body><form method="post" action="check.php">
user: <input type="text" name="xm" size="12"><br />
password: <input type="password" name="Pwd" size="12"><br />
<input type="submit" value="login"><br />
</form></body></html>';
?>
The check.php is as below.

session_start();
if(!isset($_SESSION["visit"]))
$_SESSION["visit"] = date("Y-m-d h:i:s");
else
echo "Your first visit was $_SESSION["visit"]";
Try using Sessions
isset will check if it has a value, if not then it will set the time. However, if it is set then it will show the time.
Method1:use cookie.
Rewrite welcome.php as below.
welcome.php
<?php
session_start();
if($_COOKIE["user"]["xm"] <> "")
$visnum = intval($_COOKIE["user"]["num"])+1;
setcookie("user[num]" , $visnum , time()+3600);
echo "welcome " . $_COOKIE["user"]["xm"];
echo "<br />This is your " . $visnum . " th" . " visit my website";
echo "<br />The latest visit time is " .$_COOKIE["user"]["dt"] ;
setcookie("user[dt]" , date("Y-m-d h:i:s") ,time()+3600);
else
echo
'<html><body><form method="post" action="check.php">
user: <input type="text" name="xm" size="12"><br />
password: <input type="password" name="Pwd" size="12"><br />
<input type="submit" value="login"><br />
</form></body></html>';
?>
Method2: use session.
