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?
