Symfony Dotenv 6.4 loadEnv .env.dist fallback behavior source Dotenv.php
💡 Result:
In Symfony 6.4, the loadEnv method in the Dotenv component implements a specific fallback mechanism for the.env file. According to the source code (Dotenv.php), if the primary.env file is missing, the component will automatically attempt to load the.env.dist file if it exists [1][2][3]. The specific logic within loadEnv is implemented as follows: if (is_file($path) ||!is_file($p = "$path.dist")) { $this->doLoad($overrideExistingVars, [$path]); } else { $this->doLoad($overrideExistingVars, [$p]); } This means that if the provided path (usually.env) is not found (is_file($path) is false) AND a file with a.dist extension exists at that location (.env.dist), the Dotenv component will load the.env.dist file instead [1][2][4]. Key points regarding this behavior: - Fallback Priority: The primary.env file always takes precedence. The.env.dist file is only used as a fallback when the primary.env file is absent [1][3]. - Modern Usage: While this fallback exists for compatibility, modern Symfony best practices emphasize that.env should be committed to the repository containing non-sensitive default values, effectively replacing the historical role of.env.dist [5]. - Overriding: This loading process respects the overrideExistingVars parameter, which determines whether values from these files can override environment variables already set by the system [6][1]. System environment variables generally always have the highest precedence and cannot be overridden by Dotenv files unless explicitly configured [5][7].

Symfony Dotenv load .env.dist if .env missing loadEnv $projectRoot/.env
💡 Result:
In Symfony, the Dotenv component's loadEnv method is designed to handle environment file loading automatically, including a fallback mechanism for the.env.dist file [1][2][3]. When calling $dotenv->loadEnv($projectRoot. '/.env'), the component follows these behaviors: 1. Fallback to.env.dist: If a.env file does not exist, the component will load.env.dist if it is present [1][3]. This was implemented to allow projects to define environment variables in.env.dist when a local.env file is intentionally omitted [1]. 2. Loading Order: The loadEnv method loads files in a specific order, where subsequent files can override variables defined in previously loaded files [2][4][3]. The standard sequence (subject to file existence) is: -.env (or.env.dist if.env is missing) [2][3] -.env.local (skipped for the "test" environment) [2][4][3] -.env.$env (based on the APP_ENV variable) [2][3] -.env.$env.local [2][3] This logic is typically invoked in the project's bootstrap file (e.g., config/bootstrap.php) to ensure environment variables are populated before the application kernel or other components are initialized [5][3]. Note that actual system environment variables always take precedence over values defined in these.env files [6].

raw github symfony dotenv 6.4 src Symfony Component Dotenv Dotenv.php is_file projectRoot .env.dist
💡 Result:
In Symfony's Dotenv component (including version 6.4), the logic regarding .env.dist is implemented within the loadEnv() method of the Dotenv.php class [1][2][3]. The relevant code snippet typically appears as follows: if (is_file($path) ||!is_file($p = "$path.dist")) { $this->doLoad($overrideExistingVars, [$path]); } else { $this->doLoad($overrideExistingVars, [$p]); } This logic performs the following behavior: 1. It checks if the primary environment file (defined by $path, usually .env) exists using is_file($path) [1][2]. 2. If the primary file exists, it loads that file. 3. If the primary file does not exist, it checks if a corresponding .dist file exists (e.g., .env.dist) using is_file($p = "$path.dist") [1][2]. 4. If the .dist file exists (and the primary file does not), it loads the .dist file instead [1][2]. This mechanism is designed to support projects that provide a template file (like .env.dist or .env.example) for developers to copy and populate while ensuring the application can still load configuration if the main file is missing [1][2].

Don’t let .env.dist become the signed secret.
loadEnvironmentVariables() also triggers Dotenv when .env.dist exists, and Symfony Dotenv will load .env.dist if .env is absent. Since PHPLIST_SECRET=%s, anyone missing Composer script output can run with the literal template value as the signing secret. Keep .env.dist strictly template-only and fail fast unless a real generated/supplied secret exists.
