多个文件上的切换语句（例如，用于切换情况语句的插件系统）

Question

I want to create something like a plugin-system for dynamic switch statements like in the following example:

$command = $_POST['cmd'];
switch ($command) {

 include "./Ajax_Includer.php";

}

The File "Ajax_Includer" should now load all files in a specific folder. These files all contain one case-statement.

The advantage of this should be that I can add as many case-statements as my fingers can. And also the removal of the case statements would be easier by just killing or ignoring the file with the specific case-statement.

But I get an Error that I cannot use "Include" directly inside a switch. Does anyone know a workaround or is this not possible?

Answer 1

Break it like:

switch ($command) {
    case 'your_first_case':
        $file = "./Ajax_Includer.php";
        break;

    default:
        $file = null;
        break;
}
if($file){
    include $file
}

Although including files in switch is perfectly valid.

Update: If you want your 'case's in the included file, you'll get yourself a parse error, as switch() is

expecting case (T_CASE) or default (T_DEFAULT) or '}'
