Try-Catch沒有捕捉到自定義的異常類型

Question

這是一個非常簡單的問題，它公然是我自己的newb狀態，阻止我回來。道歉。

爲什麼這段代碼不工作？

try 
    { 
     create_account($accountXML); 
     echo "<p>Successfully created your account.</p>"; 
     try 
     { 
      create_page($pageXML,$base64_credentials); 
      echo "<p>Successfully created your page!</p>"; 
     } 
     catch (exception $e){ echo "<p>$e</p>"; } 
    } 
    catch(exception $e) 
    { 
     echo "<p>$e</p>";   
    } 
    catch(emailInUseException $e) 
    { 
     echo "<p>Error: Email already in use. Could not create account.</p>"; 
    } 

內create_account功能...

if ((!substr_count($response, "200 Account created successfully") > 0)) // If failed 
{ 
    if ((substr_count($response, "400 EmailAddressInUse") > 0)) // If email address already in use 
     { 
      throw new emailInUseException($response); 
     } 
     throw new exception("Error: Could not create account. Reason: $response"); 
} 

的emailInUse捕捉似乎並不奏效:(

更新：調試啓用我收到以下錯誤： Fatal error: Class 'emailInUseException' not found

我確定這真的很明顯。謝謝你任何幫助。

Answer 1

catch(emailInUse $e) 
    { 
     echo "<p>Error: Email already in use. Could not create account.</p>"; 
    } 
    catch(exception $e) 
    { 
     echo "<p>$e</p>";   
    } 

您需要更改訂單。更一般的異常需要到底，否則你的代碼只會捕獲它並在發現特定異常之前拋出異常。
