【问题描述】：

我的网站上有一个联系表格，它会将其内容邮寄到一个电子邮件 ID。 我已经使用 phpMailer 完成任务，但密码是直接存储的 在一个变量中。我想从 .env 文件中加载密码。我怎么做？ 代码如下：

<?php
  use PHPMailer\PHPMailer\PHPMailer;
  use PHPMailer\PHPMailer\SMTP;
  use PHPMailer\PHPMailer\Exception;

    require '../vendor/autoload.php';

    $mail = new PHPMailer(true);

    $firstName = $_POST['firstName'];
    $lastName = $_POST['lastName'];
    $email = $_POST['email'];
    $message = $_POST['message'];

    if (!filter_var($email, FILTER_VALIDATE_EMAIL)) 
      header("location: ../index.php?error=invalidemail");
     else if(filter_var($email, FILTER_VALIDATE_EMAIL)) 
      try 
        //Server settings
        $mail->SMTPDebug = SMTP::DEBUG_SERVER;                      //Enable verbose debug output
        $mail->isSMTP();                                            //Send using SMTP
        $mail->Host       = 'smtp.gmail.com';                     //Set the SMTP server to send through
        $mail->SMTPAuth   = true;                                   //Enable SMTP authentication
        $mail->Username   = '[e-mail]';                     //SMTP username
        $mail->Password   = 'PASSWORD';                               //SMTP password
        $mail->SMTPSecure = PHPMailer::ENCRYPTION_SMTPS;            //Enable implicit TLS encryption
        $mail->Port       = 465;                                    //TCP port to connect to; use 587 if you have set `SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS`
    
        //Recipients
        // $mail->setFrom('[e-mail]', 'Name');
        $mail->addAddress('[e-mail]');     //Add a recipient
        // $mail->addAddress('[e-mail]');               //Name is optional
        // $mail->addReplyTo('[e-mail]', 'Information');
        // $mail->addCC('[e-mail]');
        // $mail->addBCC('[e-mail]');
    
        //Attachments
        // $mail->addAttachment('/var/tmp/file.tar.gz');         //Add attachments
        // $mail->addAttachment('/tmp/image.jpg', 'new.jpg');    //Optional name
    // .'<br>'
        //Content
        $mail->ishtml(true);                                  //Set email format to HTML
        $mail->Subject = 'New Form Submission in Website';
        $mail->Body    = '<h1>There is a new form submission in the website, here are the details:</h1> <br>' . 'Name: '.$firstName .' '.$lastName .'<br>' .'Email: ' .$email.'<br>' . 'Message:'.'<br>'. $message;
        // $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
    
        $mail->send();
        echo 'Message has been sent';
        header("location: ../index.php?error=none");
     catch (Exception $e) 
      header("location: ../index.php?error=stmtfailed");
    
   

这是我的 .env 文件的样子：

PASSWORD="PASSWORD"

如何从 env 文件中获取密码？

【参考方案1】：

你可以试试这个。

$_ENV["PASSWORD"]

【参考方案2】：

您可以使用symfony/dotenv。先用composer安装，然后这样：

use Symfony\Component\Dotenv\Dotenv;

$dotenv = new Dotenv();
$dotenv->load(__DIR__.'/../.env'); // please update this path for your case

// You will get the variable both in
// $_ENV['PASSWORD'] and $_SERVER['PASSWORD'].
$password = $_ENV['PASSWORD'] ?? '';
