How to create an HTTPS certificate for localhost domains

How to create an HTTPS certificate for localhost domains

This focuses on generating the certificates for loading local virtual hosts hosted on your computer, for development only.

Do not use self-signed certificates in production ! For online certificates, use Let's Encrypt instead (tutorial).

A list of free email provider domains. Some of these are probably not around anymore. I've combined a dozen lists from around the web. Current "major providers" should all be in here as of the date this is created.

Functions for querying directly into map[string]interface{}
// Package sqlmap provides functions for querying directly into
// map[string]interface{}.
//
// In developing really simple api endpoints, I found the boilerplate needed
// to take the results of a database query and output them as JSON to be
// really fucking annoying; make a custom struct, scan into that struct, if
// there are multiple rows do the whole rows.Next() song and dance, and if
// anything changes update the three spots each column of the result is now
// dependent on. Even when using libraries like sqlx, there's still a lot of
// extraneous code that needs to be written.

Complete overview of the PHP SessionHandler life-cycle

This page provides a full overview of PHP's SessionHandler life-cycle - this was generated by a set of test-scripts, in order to provide an exact overview of when and what you can expect will be called in your custom SessionHandler implementation.

Each example is a separate script being run by a client with cookies enabled.

To the left, you can see the function being called in your script, and to the right, you can see the resulting calls being made to a custom session-handler registed using session_set_save_handler().
