Php 将post表单值存储在隐藏的输入数组中

php html

Php 将post表单值存储在隐藏的输入数组中,php,html,Php,Html,我是php新手，下面是我的数字猜测游戏代码。因为我不知道如何定义一个随机数，所以我自己选择了80。我试图在正确猜测之前存储所有猜测，在正确猜测之后，在屏幕上打印出来。但我似乎不能把它弄对，因为它只打印出正确猜测之前的最后一个猜测感谢您的帮助 <html> <head> </head> <body> <?php $allguesses = array(); if($_SERVER["REQUEST_METHOD"] == "POST"){

我是php新手，下面是我的数字猜测游戏代码。因为我不知道如何定义一个随机数，所以我自己选择了80。我试图在正确猜测之前存储所有猜测，在正确猜测之后，在屏幕上打印出来。但我似乎不能把它弄对，因为它只打印出正确猜测之前的最后一个猜测

感谢您的帮助

<?php 
$allguesses = array();
if($_SERVER["REQUEST_METHOD"] == "POST"){
    $t = $_POST["guess"];
    $sayi = 80;

    if($sayi >$t){
        echo 'Guess higher';
    }elseif($sayi == $t){
        echo "You've guessed it right!<br>";
        echo 'Guessed numbers: <br>';

课程似乎最适合你的学习曲线
会话允许正常的无状态http协议在每次提交表单之间记住内容。因此，我们将在会话中将每个猜测保存在一个猜测数组中，在PHP中也是一个数组
<?php 
session_start();  // create a session, or reconnect to an existing one

if( $_SERVER["REQUEST_METHOD"] == "POST" && isset($_POST["guess"]) ) {
    $_SESSION['guesses'][] = $_POST["guess"];   // keep an array of guesses

    // $t = $_POST["guess"]; no need for extra variables on the stack
    $sayi = 80;

    if($sayi > $_POST["guess"]){
        echo 'Guess higher';
    }elseif($sayi == $_POST["guess"]){
        echo "You've guessed it right!<br>";
        echo 'Guessed numbers: <br>';
        foreach($_SESSION['guesses'] as $guess){
            echo $guess . ',';
        }
        $_SESSION['guesses'] = array();  // clear the old guesses out
    }else{
        echo 'Guess lower';
    }
}
?>
<html>
<head>
</head>
<body>
<form method="post">
    Guess the number:
    <input type="number" name="guess" min ="1" max = "100"><br>
    <input type="submit" name="submit">
</form>
</body>
</html>

删除了未编入的代码
用下面的代码更改了显示先前猜测的方法
echo implode( ", ", $_POST["tmn"] ); // cleaner 

此块处理将以前的猜测存储到用于显示以前猜测的数组中
if( isset( $_POST ) ) {
        $_POST["tmn"][] = $t;
    }

修正了先前版本的代码块，以便正确输出先前猜测的隐藏

<?php
    if( isset( $_POST["tmn"] ) ) {
        foreach($_POST["tmn"] as $x){
            echo "\n<input type ='hidden' name = 'tmn[]' value='$x'>";
        }
    }
?>

对于随机数，您可以使用。要存储猜测，可以使用全局变量$\u SESSION

<html>
    <head>
    </head>
    <body>
        <?php 
        //start session (needed to use the $_SESSION variable)
        start_session();
        if($_SERVER["REQUEST_METHOD"] == "POST"){

            //if empty -> initalize array
            if (empty ($_SESSION['allguesses']){
                $_SESSION['allguesses'] = array ()
            }

            $t = $_POST["guess"];
            $sayi = 80;

            if($sayi >$t){
                echo 'Guess higher';
            }elseif($sayi == $t){
                echo "You've guessed it right!<br>";
                echo 'Guessed numbers: <br>';

                //echo all guesses from $_SESSION variable
                foreach($_SESSION['allguesses'] as $y){
                    echo $y . ',';
                }

            }else{
                echo 'Guess lower';
            }

            //push in $_SESSION variable
            array_push($_SESSION['allguesses'],$t);
        }
        ?>
        <form method="post">
            Guess the number:
            <input type="number" name="guess" min ="1" max = "100"><br>
            <input type="submit" name="submit">
        </form>

使用$\u会话或一些服务器端存储-数据库、文件等。非常感谢！非常感谢你@不客气。你介意接受我的回答吗？谢谢，这就是我一直在寻找的！
