switch case語句是否靈活？

Question

我創建了以下代碼，因此當用戶選擇一個部門（銷售部門，帳單，市場營銷部門，財務部門等）並使用我創建的聯繫人表單時，電子郵件將發送給公司中的適當人員。

<?php 

$ip = $_POST['ip']; 
$httpref = $_POST['httpref']; 
$httpagent = $_POST['httpagent']; 
$visitor = $_POST['visitor']; 
$visitormail = $_POST['visitormail']; 
$notes = $_POST['notes']; 
$attn = $_POST['attention']; 
$prefphone = $_POST['phone']; 
$contact_pref = $_POST['contact']; 
$subject = $_POST['subject']; 



if (eregi('http:', $notes)) { 
    die ("Do NOT try that! ! "); 
} 
if(!$visitormail == "" && (!strstr($visitormail,"@") || !strstr($visitormail,"."))) 
{ 
    echo "<h2>Use Back - Enter valid e-mail</h2>\n"; 
    $badinput = "<h2>Feedback was NOT submitted</h2>\n"; 
    echo $badinput; 
    die ("Go back! ! "); 
} 

if(empty($visitor) || empty($visitormail) || empty($notes)) { 
    echo "<h2>Use Back - fill in all fields</h2>\n"; 
    die ("Use back! ! "); 
} 

$todayis = date("l, F j, Y, g:i a") ; 

$attention = $attention ; 
$subject = $attention; 

$notes = stripcslashes($notes); 

$message = " $todayis [EST] \n 
Attention: $attn \n 
From: $visitor ($visitormail)\n 
Please contact me by: $contact \n 
Phone Number: $phone \n 
Subject: $subject \n 
Message: $notes \n 
Additional Info : IP = $ip \n 
Browser Info: $httpagent \n 
Referral : $httpref \n 
"; 

$from = "From: $visitormail\r\n"; 



switch ($attention) { 
    case "Residential": 
     mail("mike@company.com", $subject, $message, $from); 
     break; 
    case "Billing": 
     mail("mike@company.com", $subject, $message, $from); 
     break; 
    case "Service": 
     mail("service@company.com", $subject, $message, $from); 
     break; 
    case "Technical": 
     mail("service@company.com", $subject, $message, $from); 
     break; 
} 

?> 

當客戶端接收電子郵件的發件人：字段狀態發件人的電子郵件，這是罰款，除了技術支持部門的所有部門。該部門需要事先知道發件人的電子郵件，因此我需要對其進行編碼，因此，當選擇技術選項並收到電子郵件時，該地址是默認地址（即technical@company.com）。

不知道如何做到這一點，如果這可以使用switch/case語句來完成？

我可能只是在這裏失去了一些東西，但你能不能只替換：

case "Technical": 
     mail("service@company.com", $subject, $message, $from); 
     break; 

與

case "Technical": 
     mail("service@company.com", $subject, $message, $technical_emailaddress); 
     break; 

開關罩內？
