如何在将文本框中的一系列电子邮件发送到wp_mail() 作用

$emails = \'test@test.com;test2@test2.com
email3@email3.com,email4@email4.com, email5.com\';

$emails = preg_split(\'/[;,\\n]/\', $emails);
$validEmails = array();
$subject = \'Hey Subject\';
$message = \'I am a message\';

foreach($emails as $key=>$value){
  if (is_email($value)) {
    array_push($validEmails, $value);
  }
}

wp_mail($validEmails, $subject, $message, $headers);

上面的示例代码在if (is_email()) 条件在发送到邮件功能之前，如何验证阵列中的每封电子邮件（无论以何种方式）？

// Make sure your email strings only uses comma as a separator
$emails = preg_replace(\'~[,;\\s]+~\', \',\', $emails);
