我的数字游戏就差一点就成功了，但出于某种原因我被卡住了。我将变量存储在一个隐藏的表单中，但是每次页面被发送时，它都会重置数字，然后就永远无法得到正确的数字。有什么想法吗？我的代码在下面：
<?php
// generate a random number for user to guess
$number = rand(1,100);
if($_POST["guess"]){
// grab the user input guess
$guess = $_POST['guess'];
$numbe = $_POST['number'];
if ($guess < $number){
echo "Guess Higher";
}elseif($guess > $number){
echo "Guess Lower";
}elseif($guess == $number){
echo "You got it!";
}
echo "<br />Random Number:".$number."<br />";
echo $guess;
}
?>
