在foreach循环中调用require_once(），代码在每次迭代中都不可用

我有一个电子邮件数组，想为数组中的每个条目发送一封电子邮件，但目前它只将其发送到第一个地址。我环顾四周，看不出我做错了什么。

//This is the array
$emails = array($teamleademail, $coleademail, $sponsoremail, $facilitatoremail, $cisupportemail);
//Now the foreach statment    
foreach ($emails as $value) {
    //pulls in email sending code
    require_once ("Mail.php");
    //variables required to send the email 
     $from = "Scope Sheet Process Database (no reply)<scopesheetprocess@goodrich.com>";
     //Make the $to variable that of the email in the array
     $to = "$value";
     $subject = "Scope Sheet $scopesheetid Closed";
     $body = "Scope Sheet $scopesheetid has been closed and can no longer be edited.";
     //send email code
     require_once ("sendemail.php");
}  

由于IT问题，我使用pear-php发送电子邮件，但这并不重要，因为它每次都应该运行脚本并发送单独的电子邮件。
