Introduction

Laravel, Symfony, and other modern PHP frameworks use environment variables to store security credentials and configuration that changes from one machine to the next.

The latest Laravel release made a small change to the way environment variables are loaded. This change ended up breaking third-party libraries and Laravel itself.

Resetting OpenCFP

If you've used OpenCFP for a conference and want to use it next year you have to reset all talks. It is a good idea to keep users though.

That's how to do it:

Backup your current database.
Adjust dates in config/production.yml.
Clean up database:

	<?php

	// see https://gist.github.com/Nex-Otaku/622ce7f2f336f27b4953e85efffa7c45

	class Timestamp
	{
	private int $intTimestamp;

	private function __construct(int $intTimestamp)
	{

	public static function assertArrayStructure($keys, $array)
	{
	$arrayKeys = array_keys($array);

	$missing = array_diff($keys, $arrayKeys);
	$unexpected = array_diff($arrayKeys, $keys);

	$message = 'Keys are wrong.';
	if ($missing !== []) {
	$message .= ' Missing: ' . implode(', ', $missing) . '.';
