💡 Hint

Common Mistakes

Using the variable name without the env function.

Using PHP's getenv instead of Laravel's env.

To get the database host value from the environment in Laravel, use env('DB_HOST'). The other options are either incorrect syntax or not Laravel standard.

💡 Hint

Common Mistakes

Not quoting the variable name in code.

Using unquoted values with spaces in .env.

In the .env file, values are assigned without quotes unless spaces exist, so quotes are optional but recommended for clarity. In code, the variable name must be a string in quotes.

5fill in blank

💡 Hint

Common Mistakes

Not quoting the environment variable name or default value.

Using single quotes inconsistently.

The environment variable name must be a string in quotes. The default fallback should be a string in quotes. The comment shows the default value as a plain string for clarity.
