ThinkPHP6 Configuration and Environment Variable Setup Guide

1. Regular Configuration

The config folder is the default configuration directory for a ThinkPHP6 application. You can modify the existing configuration files or add custom ones, but avoid renaming files or changing unfamiliar settings, as this may render the application unusable.

2. env Environment Variable Definition

When you download ThinkPHP6, the project root contains a .example.env file. Rename this file to .env and edit its contents to define your environment variables.

APP_DEBUG = true
[APP]
DEFAULT_TIMEZONE = Asia/Shanghai
[DATABASE]
TYPE = mysql
HOSTNAME = 127.0.0.1
DATABASE = test
USERNAME = username
PASSWORD = password
HOSTPORT = 3306
CHARSET = utf8
DEBUG = true
[LANG]
default_lang = zh-cn

The APP_DEBUG = true line enables ThinkPHP6's debug mode, allowing you to see detailed error information during development.

To retrieve environment variables in code, import the think\facade\Env facade; variable names are case‑insensitive.

To configure the database, edit the .env file and set the following entries:

DATABASE = tp
USERNAME = root
PASSWORD = root

Correspondingly, update config/database.php to read these values using the env helper:

// Database name
'database' => env('database.database', 'tp'),
// Username
'username' => env('database.username', 'root'),
// Password
'password' => env('database.password', 'root'),
