将 MVC PHP 视图捕获到变量中以作为正文邮件传递到 PHPMailer

Question

我正在使用 MVC 框架，我想将视图传递到 PHPMailer 正文中，但我无法将视图捕获到变量中。

控制器处理视图如下所示：

// Load View
public function view($view, $data = []){
    // Check for view file
    if(file_exists('../app/views/'.$view.'.php')){
        require_once '../app/views/'.$view.'.php';
    }else{
        // View does not exist
        die('View does not exist');
    }
}

在控制器中，我将视图传递给函数 sendMail，但它首先加载它，然后我得到一个错误 file_get_contents()：文件名不能为空：

$bodyMail = file_get_contents($this->view('booking/mailbody'));

sendEmail($bookingNumber, $id, $mailAddress, $bodyMail);

处理PHPMailer函数的辅助函数：

function sendEmail($bookingNumber, $id, $mailAddress, $bodyMail){

$mail = new PHPMailer(true);

//Enable SMTP debugging.
$mail->SMTPDebug = 3;
//Set PHPMailer to use SMTP.
$mail->isSMTP();
//Set SMTP host name
$mail->Host = "*********";
//Set this to true if SMTP host requires authentication to send email
$mail->SMTPAuth = true;
//Provide username and password
$mail->Username = "**********";
$mail->Password = "********";
//If SMTP requires TLS encryption then set it
$mail->SMTPSecure = "tls";
//Set TCP port to connect to
$mail->Port = 587;

$mail->From = "********";
$mail->FromName = "*******";

$mail->addAddress($mailAddress);
$mail->addAddress('*********');

$mail->isHTML(true);

$mail->Subject = "Reservation confirmed: ".$bookingNumber.$id."";
$mail->Body = $bodyMail;
$mail->AltBody = "This is plain text of mail";

try {
    $mail->send();
    echo "Message has been sent successfully";
} catch (Exception $e) {
    echo "Mailer Error: " . $mail->ErrorInfo;
}

我的问题是有没有办法将视图捕获到变量中？你会以不同的方式处理这个问题吗？如果是这样，你们能告诉我正确的方向吗？

根据我的评论，我建议使用输出缓冲来捕获视图的输出

https://www.php.net/manual/en/function.ob-get-clean.php

并且正如@synchro 所建议的那样，检查您对 require_once()

的使用情况

// Load View, but capture it with output buffering
public function viewBuffered($view, $data = []){
    // Check for view file
    if(file_exists('../app/views/'.$view.'.php')){
        ob_start();
        require_once '../app/views/'.$view.'.php';
        return ob_get_clean();
    }else{
        // View does not exist
        die('View does not exist');
    }
}

-或-

// Load View, but capture it with output buffering
public function viewBuffered($view, $data = []){
    ob_start();
    $this->view($view,$data);
    return ob_get_clean();
}
