Php 通过include调用函数

如何将一页包含到另一页中

例如，第1页包括第2页。第2页在获得正确的参数之前不会显示任何内容

这是第2页的直接url调用

www.mypage.com/execute.php?cmd=test

输出是hello world

但是当将同一页包含到第1页时

include('execute.php?cmd=test');

或

---

对不起，我想你们不太明白我的意思。我想做的是，第2页有一些内容必须只在需要时显示，因此我在第2页创建了一个函数，这样我就可以调用它。必须通过呼叫在第1页查看的内容。因此，我尝试了执行“execute.php？cmd=test”正常工作的方法，但这次不行了，我想您应该这样做：

$test = $_GET['cmd'];

---

这将在两个页面中都起作用。

我想您应该这样做：

$test = $_GET['cmd'];

---

这将在两个页面中都起作用。

虽然我认为我理解您的意图，但这是错误的方法。使用两个页面都将包含的第三个PHP脚本。这样，您就不必破解

$\u GET

超级全局变量

包括/somescript.php

// do something with $cmd
if ($cmd == 'test') echo 'Hello world';

$cmd = 'test';
include 'includes/somescript.php';

$cmd = $_GET['cmd'];
include 'includes/somescript.php';

function execute($cmd) {
   // ...
}

include `includes/somescript.php';

execute('test');

class CommandHandler {
    public function execute($cmd) {
        //...
    }
}

include `includes/somescript.php';

$h = new CommandHandler();
$h->execute($_GET['cmd']);

page1.php

// do something with $cmd
if ($cmd == 'test') echo 'Hello world';

$cmd = 'test';
include 'includes/somescript.php';

$cmd = $_GET['cmd'];

当然，文件

includes/somescript.php

不应该这样执行，它应该包含一个

函数或一个包含参数的类，然后从页面中调用。这取决于你，如果你要去OO或程序化

第一种语法不会让您走得太远。第二个可以，但是您也可以直接设置一个变量并在execute.php中引用它，而不使用$\u GET public变量。第二个可以，但是您也可以直接设置一个变量，并在execute.php中引用它，而不使用$\u GET public变量。
