php - 在不同的文件中拆分开关案例

Question

我有一个 php 文件，我在其中使用了一个非常长的开关盒。我想将案例拆分到不同的文件中(将逻辑上相关的案例保存在 1 个文件中)。

编辑:对不起大家，是我的代码导致了问题。开关盒按预期工作。

文件 -> a.php

echo "<br>RES = ".test(1);

function test($value) {
    switch($value) {
        case (1 || 2):
                include("b.php");
                            **return $temp;**
                break;

        default: echo "error";
                return 3;
                break;
    }
}

文件 -> b.php

switch($value) {

    case 1: echo "value is 1";
                    **$temp = 1;**
            return 1;
            break;

    case 2: echo "value is 2";
                    **$temp = 2;**
                    return 2;
                    break;
}

如何获得正确的结果？如果 b.php 的开关盒在 a.php 文件中，那么一切正常。关于如何执行此操作的任何想法/建议？

如果我添加 $temp(粗线)那么它就可以工作...

提前感谢您的帮助。

更新问题的更新回复: 修改“a.php”并在“b.php”前面添加一个返回前缀包括:

return include("b.php");

http://www.php.net/manual/en/function.include.php

Handling Returns: It is possible to execute a return() statement inside an included file in order to terminate processing in that file and return to the script which called it. Also, it's possible to return values from included files. You can take the value of the include call as you would a normal function. This is not, however, possible when including remote files unless the output of the remote file has valid PHP start and end tags (as with any local file). You can declare the needed variables within those tags and they will be introduced at whichever point the file was included.

在您的 case/break 部分中使用简单的 include()？

switch($var)
{
 case 1:
   include('case_1.php');
   break;
 case 2:
   include('case_2.php');
   break;
 default:
   include('case_default.php');
  break;
}
