# How to Call `.env` Variables in Laravel Blade Templates: The Correct Way As a senior developer working with the Laravel ecosystem, you frequently encounter the need to inject configuration values—like application names, API keys, or settings stored in your `.env` file—directly into your Blade templates. It is a common point of confusion when developers try to mix raw PHP logic with Blade's powerful templating syntax. If you’ve encountered issues where trying to use `{{ env('APP_NAME') }}` results in raw code output, it usually points to a misunderstanding of how the Blade engine processes data versus how standard PHP executes. This post will diagnose why this happens and provide the correct, idiomatic Laravel way to access environment variables within your views. ## The Root of the Confusion: Blade vs. Raw PHP The core issue lies in the distinction between two environments: the **Blade Templating Engine** and **Native PHP Execution**. When you write `{{ env('APP_NAME') }}`, you are instructing the Blade compiler to evaluate the expression inside and output its result as plain text into the HTML stream. This is a data interpolation feature specific to Blade. However, if you try to embed this within a context that expects raw PHP execution (like directly inside a standard `` block without proper escaping or context), the engine might treat it differently, leading to unexpected output, such as the raw function call itself instead of the value. Your attempt to use `@section` and `{{ env('APP_NAME') }}` is fundamentally correct for Blade syntax, but if you are seeing the literal code displayed, it suggests that the context surrounding the variable access is overriding or misinterpreting the Blade instruction. ## The Correct Implementation: Mastering Blade Interpolation The definitive way to pull environment variables into your Blade templates is by using the double curly braces `{{ ... }}` for interpolation and leveraging Laravel's global helper functions, specifically the `env()` helper. ### 1. Accessing Variables in Sections When defining dynamic content within sections, you simply use the standard Blade syntax: ```blade {{-- master.blade.php --}} ``` Notice that we are using `!!` (raw output) here, which is often necessary when dealing with HTML attributes like `
