我想验证一些电子邮件地址。输入由用户在文本区域中给出,地址用逗号分隔,如下所示:

email1@domain1.com、email2@domain2.com 等等等等。

这是我用来检查地址的脚本:

    $emailadressen = explode(',', $_POST['uitnodigen']);

        $aantal = count($emailadressen);
        $i = 1;

     foreach($emailadressen as $emails)
       {    
             if(check_email_address($emails) == false)    {
             $Melding['omschrijving'] = '<div class="error">Error in address number '.$i.'</div>';
             $i++;
             }
       }

这是我使用的功能:

   function check_email_address($email) {
    // First, we check that there's one @ symbol, and that the lengths are right
    if (!preg_match("/^[^@]{1,64}@[^@]{1,255}$/", $email)) {
        // Email invalid because wrong number of characters in one section, or wrong number of @ symbols.
        return false;
    }
    // Split it into sections to make life easier
    $email_array = explode("@", $email);
    $local_array = explode(".", $email_array[0]);
    for ($i = 0; $i < sizeof($local_array); $i++) {
        if (!preg_match("/^(([A-Za-z0-9!#$%&'*+\/=?^_`{|}~-][A-Za-z0-9!#$%&'*+\/=?^_`{|}~\.-]{0,63})|(\"[^(\\|\")]{0,62}\"))$/", $local_array[$i])) {
            return false;
        }
    }
    if (!preg_match("/^\[?[0-9\.]+\]?$/", $email_array[1])) { // Check if domain is IP. If not, it should be valid domain name
        $domain_array = explode(".", $email_array[1]);
        if (sizeof($domain_array) < 2) {
            return false; // Not enough parts to domain
        }
        for ($i = 0; $i < sizeof($domain_array); $i++) {
            if (!preg_match("/^(([A-Za-z0-9][A-Za-z0-9-]{0,61}[A-Za-z0-9])|([A-Za-z0-9]+))$/", $domain_array[$i])) {
                return false;
            }
        }
    }

    return true;
}

当数组只包含一个电子邮件地址时,没有问题,一切正常。

但是当我至少有 2 个电子邮件地址时,我每次都会收到 FALSE 错误。(即使电子邮件地址有效)

我做错了什么?

我会用

filter_var($email, FILTER_VALIDATE_EMAIL) 

和:

filter_var($email, FILTER_SANITIZE_EMAIL)

就像

   foreach($emailadressen as $email)
   {    
   if(filter_var($email, FILTER_SANITIZE_EMAIL === FALSE) || 
      filter_var($email, FILTER_VALIDATE_EMAIL) === FALSE)
    {
    $Melding['omschrijving'] = 
    '<div class="error">Error in address number '.$i.'</div>';
    $i++;
   }
   }

使用filter,您应该能够简单地使用:

foreach($emailadressen as $emails)
{    
    if(!filter_var($emails, FILTER_VALIDATE_EMAIL))
    {
        $Melding['omschrijving'] = '<div class="error">Error in address number '.$i.'</div>';
        $i++;
    }
}

不需要任何巨大的功能。

这是假设在您运行此 foreach 时,帖子中的数组仅包含电子邮件。

我认为您的电子邮件地址中添加了空格尝试使用修剪

    foreach($emailadressen as $emails) {
        if(check_email_address(trim($emails)) == false)    {
            echo '<div class="error">Error in address number '.$i.' ' . $emails. '</div>';
        }
        else {
            echo '<div class="noerror">No Error in address number '.$i. ' ' . $emails. '</div>';
        }
        $i++;
    }
