將 php 的 output 值輸入瀏覽器？
[英]Input and output values for php into the browser?
問題描述
我剛開始在 php 上學習我的模塊，兩個月前完成了 Javascript 我熟悉很多元素，但有點生疏。 基本上，我用 html 設置了一個表格，並添加了一點 css 使它漂亮。 學校讓我們做一些通用的練習。 我現在如何使用 Javascript 來獲取值等
document.getElementById("textBox").value;
並通過我創建的 div 返回 output
document.getElementById("return").innerHTML =... ;
老實說，我不知道如何用 php 做到這一點，我相信這很容易，但我一生都無法在網上找到解決方案，而且學校的視頻也很模糊。
練習者是“創建一個向用戶詢問數字 (1-7) 並返回與輸入的數字相關聯的星期幾的應用程序。您必須驗證數字”
這是我到目前為止的代碼....

如果它有任何區別，這就是瀏覽器的樣子，所以你理解我的問題

下面的代碼應該可以幫助您理解。
<?php
$response = "";
if(isset($_POST) && isset($_POST["mytext"])): /// check if user submitted form
$num = $_POST["mytext"]; //put form mytext variable.. retrieved from html <input name="mytext"....
if(is_numeric($num)):
switch($num):
case "1":
$response = "Monday";
break;
case "2":
$response = "Tuesday";
break;
case "3":
$response = "Wednesday";
break;
case "4":
$response = "Thursday";
break;
case "5":
$response = "Friday";
break;
case "6":
$response = "Saturday";
break;
case "7":
$response = "Sunday";
break;
default:
$response = "Invalid number";
endswitch;
else:
$response = "Invalid number";
endif;
endif;
?>

與 Javascript 不同，php 完全不同，Javascript 的功能可以在 HTML 中通過使用 ZC0BB2196426022E8AEDZFA 來訪問，加載。 等等，屬性。 但是php的功能卻大不相同，只能通過php代碼訪問。 首先，您需要使用一種方法創建一個舞會，然后發送到同一頁面（在您的情況下），然后運行您應用的條件，最后像我在其中所做的那樣回顯結果。

希望您必須在合適的服務器上運行這些 php 代碼！ 好走！
