PHP overview

Overview

Smarty package comes with PHP "micro framework" helping you to get started.
Is written from scratch but kept as simple as possible so you can extract what you need.

If you already use a php framework like Laravel, etc, you definitely don't need it. But there are also some helpers you might need.

An useful class might be php/sow_core/sow.smtp.php - a SMTP class using redundcancy to send emails. You can add to config.inc.php multiple SMTP email providers (your own hosting, Amazon SES, Mailgun, etc) and the SMTP class will try to send the email using the first available provider. If the first one fail, will try the next one and so on.

SOW PHP functions

All functions below are added to php/index.php (all of them are commented by default). You can uncomment one at a time to test/see how it's working on your local webserver. PHP 7.x is recommended but also works with 5.3+
