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().

Raw CSV data is made available by Common Data Hub here:

http://www.commondatahub.com/live/geography/state_province_region/iso_3166_2_state_codes

http://www.commondatahub.com/live/geography/country/iso_3166_country_codes

The table cdh_state_codes (see cdh-schema.sql below) is designed to hold the raw data, which should import readily using most common database tools, or directly into MySQL via LOAD DATA, e.g.:

SET FOREIGN_KEY_CHECKS=0;

TRUNCATE TABLE iso3166.cdh_state_codes;

Upgrading PHP

Guidelines for upgrading the minimum PHP version requirements of packages and projects.

This isn't meant to be an exhaustive guide to upgrading, but as a checklist for the most important upgrades.

PHP 5.3

The first version to support namespaces - any relevant PHP packages/projects usually have this version as the minimum requirement, so this document won't concern itself with upgrades prior to that.

Introduction

⚠️ I am no longer actively maintaining this. ⚠️

With the Windows 10 Creators Update comes an awesome new opportunity to run a lighweight Ubuntu Linux environment as a subsystem of Windows. This is officially known as Windows Subsystem for Linux (WSL) or Bash on Windows.

This is great news for PHP developers using Windows - we can now get access to native Linux builds of PHP, PECL extensions, ImageMagick, NGINX and other server components and tools, without having to migrate to a Linux desktop environment!

In this guide, we'll get you set up with WSL itself, a working PHP 8.2 environment with OpCache, XDebug and task/terminal integration with Php Storm, and working NGINX configuration - as well as various tools, including PEAR/PECL, Composer and Node.JS.
