Quest to send email from PHP
Singapore PHP User Group Meetup - May 2016
Kai Hendry
The problem
How to best send "transactional" emails from a PHP application?
- Accountable / Reliably
- Asynchronously / Non-blocking
Once upon a time, things were simple
- LAMP stack
- Postfix
But were they?
Then things got REAL
- SPAM
- _Transactional email_ not allowed from typical hosters
Third party services
How do we integrate?
SMTP or... Web services?
- AWS
- Sendgrid
Now how do we make PHP non-blocking whilst sending an email?
- register_shutdown_function
- fastcgi_finish_request
- PHPMailer
- Swift
- Pthreads
- exec
- beanstalk
My current solution
SMTP is > 3s
# php index.php

)Wish: this could be integrated into mail()
And on the browser!
fetch("https://feedback.dabase.com/feedback/feedback.php", { method: "POST", body: formData }).then(function (res) {
if (res.ok) {
console.log(res);
} else {
console.log("error", res);
}AWS SES setup
How to action on the data?
- How to monitor?
- What to do when things go wrong?
