Automated E-mail with PHP and MySQL?

Question

How can I send an automated e-mail to a users entered e-mail address?

I have Xampp, which is a local web server equipped with Apache, and Mercury for mail.

Ideas?

Answer 1

To send email: Look up the mail function .

To schedule a task in linux look up crontab.

To schedule a task in Windows look up task scheduling in the control panel.

And don't use Xampp for production. It's insecure.

Answer 2

Instead of php's mail() function you should use something like http://swiftmailer.org
You can easily do smtp-authentication, encryption, mime-mail, character encoding, batch mailing...
And you get much more reliable error reporting.

Answer 3

This is not an answer to your question, but could be relevant anyway:

My experience with a local web-server is that the mail will not get to its destination. It depends on your isp, but if you have a changing ip address every time you connect to your isp (dial-up, adsl, cable), your outgoing mail will most likely be rejected by the recipients mail server.

A lot of those ip ranges that isp give their clients are blocked by spam filters.

At least the range I am in is:)

Answer 4

Be careful though, because bad people will write scripts to submit your form with a zillion email addresses and try to send spam. They will also (try) to embed \r\n in the submitted address to write out other content and headers. I do something like this:

function sanitize($s) {
  $badheaders = array("/to\:/i", "/from\:/i", "/bcc\:/i", "/cc\:/i");
  $s = preg_replace($badheaders, '(spam)', $s);
    if (strlen($s) > 2048) {
       $s = substr($s, 0, 2048);
       $s = $s." (TRUNCATED)";
    }
    return $s;
}

then I run user inputted strings through sanitize() before calling mail(). YMMV of course.

Answer 5

You can use phpmailer to send mail via SMTP protocol, this library is pretty good ! ( Wordpress CMS use it ! )

Answer 6

php.net/mail :

mail($to, $subject, $messge);
