Deprecated messages slowing your Laravel app? Learn 3 proven methods to disable deprecated warnings in Laravel. Includes config/app.php setup, testing steps, and performance optimization tips. Works with Laravel 7, 8, 9, 10, and 11.

Quick Answer: Does APP_DEBUG=false Suppress Deprecation Warnings?

No, setting APP_DEBUG=false does NOT suppress deprecation warnings in Laravel.

This is one of the most common misconceptions among Laravel developers. The APP_DEBUG setting in your .env file only controls whether error details are displayed in the browser during development. It does not affect deprecation warnings that appear in your logs or console.

Here’s what APP_DEBUG actually controls:

• When APP_DEBUG=true: Detailed error pages are shown in the browser
• When APP_DEBUG=false: Generic error pages are shown to users (production mode)

Deprecation warnings will still appear in your Laravel logs (storage/logs/laravel.log) and console output regardless of the APP_DEBUG setting. To actually suppress deprecation warnings, you need to use the methods described below.

Methods Comparison: Which One Should You Use?

Method	Suppresses Warnings	Production Safe	Recommended
APP_DEBUG=false	No	Yes	Not for this purpose
error_reporting config	Yes	Yes	Yes – Best method
php artisan optimize	Partial (cache only)	Yes	Use with other methods
Laravel Error Handler	Yes	Yes	Advanced users

What are Deprecated Messages in Laravel?

In the world of web development, Laravel has become one of the most popular PHP frameworks due to its simplicity, elegance, and powerful features. However, like any software project, Laravel is not without its issues. One common problem that developers may encounter when working with Laravel is deprecated messages.

Deprecated messages are warnings that indicate a function, method, or feature that is no longer recommended and may be removed in future versions of the software. In Laravel, these warnings help developers identify code that needs updating to maintain compatibility with newer framework versions.

Here are some examples of deprecated messages that you may encounter in your Laravel projects:

• Functions or methods that have been replaced with newer, more efficient alternatives
• Configuration options that are no longer supported in the latest versions of Laravel
• Syntax or coding practices that may lead to performance issues or vulnerabilities

Deprecated messages can have a significant impact on the performance and stability of your application. Ignoring deprecated messages can lead to code that is difficult to maintain, slower performance, and potential security vulnerabilities.

Why Disable Deprecated Messages in Laravel?

There are several important reasons why developers should take the time to disable deprecated messages in their Laravel projects:

1. Avoiding confusion during development

Deprecated messages can clutter your development environment with unnecessary warnings, making it difficult to identify legitimate issues in your code. Disabling deprecated messages can help streamline the development process and improve code readability.

2. Optimizing application performance

Deprecated messages can slow down the performance of your application by introducing unnecessary overhead. By disabling deprecated messages, you can ensure that your application runs smoothly and efficiently.

3. Ensuring code quality and compliance

Ignoring deprecated messages can lead to code that is not compliant with Laravel best practices, making it difficult to maintain and update in the future. By disabling deprecated messages, you can ensure that your code is clean, efficient, and up to date with the latest Laravel standards.

4 Methods to Disable Laravel Deprecation Warnings

Method 1: Modify error_reporting in config/app.php (Recommended)

This is the most straightforward and recommended method for disabling deprecation warnings in Laravel. It works across all Laravel versions (7, 8, 9, 10, and 11).

Step 1: Update Laravel version to the latest stable release

Before disabling deprecated messages, ensure you are running the latest stable version of Laravel. This will help prevent future deprecated messages and ensure that your application is up to date with the latest features and improvements.

Step 2: Modify config/app.php file

To disable deprecated messages in Laravel, modify the config/app.php file in your project. Open the file in a text editor and locate or add the error_reporting configuration.

Add this line to your config/app.php file:

'error_reporting' => E_ALL & ~E_DEPRECATED & ~E_STRICT,

This configuration tells PHP to report all errors except deprecated warnings and strict standards notices.

Step 3: Testing the changes

After modifying the config/app.php file, test your application to ensure that deprecated messages are no longer being displayed. Run your tests and check for any remaining deprecated messages to confirm that the changes have been successful.

Method 2: Using php artisan optimize Command

The php artisan optimize command is useful for clearing and caching configuration, routes, and views. While it doesn’t directly suppress deprecation warnings, it can help reduce console clutter during development.

Run these commands in sequence:

php artisan config:clear
php artisan config:cache
php artisan route:cache
php artisan view:cache

What each command does:

• config:clear – Removes cached configuration files
• config:cache – Creates a single cached file for faster config loading
• route:cache – Caches all route registrations
• view:cache – Compiles all Blade templates

Note: Use this method in combination with Method 1 for best results. This alone won’t suppress all deprecation warnings.

Method 3: Custom Error Handler Configuration

For more advanced control, you can create a custom error handler in your Laravel application. This method is recommended for developers who need fine-grained control over error reporting.

Edit your app/Exceptions/Handler.php file and add:

public function register()
{
    error_reporting(E_ALL & ~E_DEPRECATED & ~E_STRICT);

    $this->reportable(function (Throwable $e) {
        // Custom error handling logic
    });
}

This gives you more control over which errors to suppress and allows you to add custom logging or handling for specific error types.

Method 4: Environment-Specific Configuration

You can also configure deprecation warnings differently for development and production environments by using .env files.

In your config/app.php, add:

'error_reporting' => env('ERROR_REPORTING', E_ALL & ~E_DEPRECATED & ~E_STRICT),

Then in your .env file:

# For development - show all errors including deprecated
ERROR_REPORTING=E_ALL

# For production - hide deprecated warnings
ERROR_REPORTING=32759  # This equals E_ALL & ~E_DEPRECATED & ~E_STRICT

Laravel 7 Specific Deprecation Issues

Laravel 7 users may encounter specific deprecation warnings when upgrading to Laravel 8 or running on newer PHP versions. Here are the most common issues and their solutions:

Issue: logger.php implicitly marking parameter $dispatcher as nullable

This warning appears when using php artisan serve with Laravel 7 on PHP 8.0+.

Solution: Either upgrade to Laravel 8+ or modify vendor/laravel/framework/src/Illuminate/Log/LogManager.php (not recommended for production). Better approach: Use the error_reporting method above to suppress these warnings.

Issue: illuminate\log\logger::__construct() deprecation

PHP 8 compatibility issue with Laravel 7’s logging system.

Solution: Update to Laravel 8 or apply the error_reporting configuration from Method 1 above. This is a framework-level issue that cannot be fixed without upgrading.

Issue: object_get deprecated

The object_get() helper function was deprecated in Laravel 7 and removed in Laravel 9.

Solution: Replace object_get() calls with data_get() or direct property access. Example:

// Old (deprecated)
$value = object_get($object, 'property.nested');

// New (recommended)
$value = data_get($object, 'property.nested');
// or
$value = $object->property->nested ?? null;

Frequently Asked Questions (FAQs)
