不允許在控制器文件中使用「 - 」字符

Question

我通過作者包下載的名稱中包含字符「 - 」。然後我得到的錯誤，當我嘗試使用它

use Marekweb\Opaque-id\OpaqueEncode; 

錯誤：

syntax error, unexpected '-', expecting ',' or ';' 

Answer 1

我不知道該怎麼你這個命名空間來了，但OpaqueEncoder類簡單地doesn't have one（因此居住在根命名空間），只需編寫use OpaqueEncoder將其導入非根名稱空間。

更新。 它沒有在所有

任何命名空間

namespace Xyz\Anything; 

use OpaqueEncoder; 

class ABC 
{ 
    public function dunno($key) 
    { 
     $encoder = new OpaqueEncoder($key); 
    } 
} 

Answer 2

I don't know the syntax, but the following guesses might help: 
    - the backward slashes, should they be forward slashes? 
    - maybe a missing semi-colon on the previous line. 
    - the '-' might not be the right '-' but rather some other dash. 
    you could try deleting and retyping it. 
    - character encoding mismatch, utf-8 vs Cp???? (or whatever) 
    - character encoding not declared at top of document or in whatever 
    meta placeholder or pragma the language provides. 
    - check the actual encoding of your document. 
You might get lucky. :)
