// 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. |
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().
