我想驗證一些電子郵件地址。 輸入由用戶在一個textarea給出的地址由逗號分隔,這樣的:PHP:驗證數組中的電子郵件地址
[email protected],[email protected]等等,等等
這是我的腳本用它來檢查地址:
$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>';
$i++;
}
}
這是我使用的功能:
function check_email_address($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;
}
當陣列中只包含一個EMAILADDRESS沒有問題和EV一切工作正常。
但是,當我至少有2個電子郵件地址時,每次都會收到FALSE錯誤。 (即使電子郵件地址有效)
我該怎麼做?
