PHP验证电子邮件地址以逗号分隔 [英] PHP validate email addresses separated by a comma

问题描述

在数据库中，电子邮件地址由逗号分隔，当有多个

我尝试使用：

  if（filter_var email_to，FILTER_VALIDATE_EMAIL））
  

但这只适用于一个电子邮件地址，如何验证多个分隔符一个逗号？

喜欢：

  [e-mail]， [e-mail] 
  

这是我的电子邮件功能：

  require_once/usr/local/lib/php/Mail.php; 
 
 $ from = $ email_from; 
 $ to = $ email_to; 
 $ subject = $ email_subject; 
 $ body = $ email_body; 
 
 $ host =mail.domain.co.uk; 
 $ username =[e-mail]; 
 $ password =*********; 
 
 $ headers = array（'From'=> $ from，
'To'=> $ to，
'Cc'=&$ $ cc，
'Subject'=> $ subject，
'Content-type'=>'text / html'）; 
 $ smtp = Mail :: factory（'smtp'，
 array（'host'=> $ host，
'auth'=> true，
'username' => $ username，
'password'=> $ password））; 
 
 $ rec = $ to。'，'。$ cc; 
 
 $ mail = $ smtp-> send（$ rec，$ headers，$ body）; 
  

如何验证$ to和$ cc中的逗号分隔值？

解决方案

尝试这样：

  foreach （'，'，$ sEmailAddresses）AS $ sEmailAddress）{
 $ bValid | = filter_var（$ sEmailAddress，FILTER_VALIDATE_EMAIL）; 
} 
 
 $ sResult =（$ bValid）？ 两个都有效：其中一个不是; 
  

a have a PHP Mail function which sends emails to addresses from a MySQL Database.

In the database, the email addresses are separated by a comma when there are multiple.

i have tried using:

if(filter_var($email_to, FILTER_VALIDATE_EMAIL))

but this only works for one email address, how can i validate multiple separated by a comma?

like:

[e-mail],[e-mail]

here is my email function:

require_once "/usr/local/lib/php/Mail.php";

            $from = $email_from;
            $to = $email_to;
            $subject = $email_subject;
            $body = $email_body;

            $host = "mail.domain.co.uk";
            $username = "[e-mail]";
            $password = "*********";

            $headers = array ('From' => $from,
              'To' => $to,
              'Cc' => $cc,
              'Subject' => $subject,
              'Content-type' => 'text/html');
            $smtp = Mail::factory('smtp',
              array ('host' => $host,
             'auth' => true,
             'username' => $username,
             'password' => $password));

             $rec = $to.', '.$cc;

            $mail = $smtp->send($rec, $headers, $body);

how can i validate the comma separated values in the $to and $cc?

解决方案

Try this:

foreach(explode(',', $sEmailAddresses) AS $sEmailAddress) {
   $bValid |= filter_var($sEmailAddress, FILTER_VALIDATE_EMAIL);
}

$sResult = ($bValid) ? 'Both are valid' : 'One of them are not';
