Try-Catch没有捕捉到自定义的异常类型

Question

这是一个非常简单的问题，它公然是我自己的newb状态，阻止我回来。道歉。

为什么这段代码不工作？

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>"; 
    } 

内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捕捉似乎并不奏效:(

更新：调试启用我收到以下错误： Fatal error: Class 'emailInUseException' not found

我确定这真的很明显。谢谢你任何帮助。

Answer 1

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

您需要更改订单。更一般的异常需要到底，否则你的代码只会捕获它并在发现特定异常之前抛出异常。
