如果不存在會傳回警告
但不會中斷
會直接嵌入form.php
介面檔的使用
<?php
include("form.php");
?>如果不存在會傳回警告
但“會”中斷
這行後面的程式就不再執行了
設定檔的使用
<?php
require("form.php");
?><?php
session_start();
?>
<!doctype html>
<html>
<head>
<meta charset="UTF-8">

<div style="border:1px solid #000000;min-height:500px;">

<?php
include_once($_GET["action"].".php");
include_once($_GET["action"].".php");
?>如果是以下的程式碼仍會出現兩次
<?php
include_once($_GET["action"].".php");
include($_GET["action"].".php");
