让这个工作有些麻烦，所以我想我会问你们。我只是想让用户简单地在输入字段中输入他们的电子邮件，然后向他们发送一封带有确认号的电子邮件。电子邮件发送，但无法获得在电子邮件中显示的确认号码。

     $cmd = 'echo "Please copy and paste the following link into your browser to confirm your registration: domain.subdomain.ca/user/confirm/"'.$confirmation_code.' | mail -s "Please confirm your login registration" foo@bar.com';
     $result = 0;

     passthru($cmd, $result);

现在我已经尝试过这种连接方式，但我也尝试过内联，因为它只是回显一个简单的语句，所以我尝试在双引号内使用 $confirmation_code ，仍然没有。还按照 passthru 文档中的建议尝试了 ${confirmation_code} 和 {$confirmation_code}。

电子邮件发送，一切正常，但我无法在电子邮件中显示确认码，所以如果有人有解决方案，将不胜感激！

You are having problem with quotes in command string. Change it to: $cmd = 'echo "Please copy and paste the following link into your browser to confirm your registration: domain.subdomain.ca/user/confirm/'.$confirmation_code.'" | mail -s "Please confirm your login registration" foo@bar.com'; and it should work.
