Resolving the "Call to Undefined Function str_random()" Error in Laravel
When working with Laravel, developers may encounter the error: Call to undefined function App\Http\Controllers\str_random(). This typically happens when attempting to use the str_random() function, which was deprecated in Laravel 6 and is no longer available in recent versions.

In this article, we’ll explain why this error occurs, how to resolve it, and provide some useful context on Laravel’s changes regarding random string generation.

Understanding the Error
The error Call to undefined function App\Http\Controllers\str_random() happens when you try to use the str_random() function, which is no longer defined in Laravel as of version 6. This function was originally part of the global helper functions provided by Laravel but was removed in favor of a more standardized approach using the Str facade.

The problem typically arises when upgrading a Laravel project to a version where str_random() has been removed or when using old code from earlier versions of Laravel.

The Cause of the Error
Laravel 6 introduced a shift in how certain helper functions were managed. The str_random() function was deprecated and eventually removed because it wasn’t part of the consistent API Laravel aimed to offer. Instead of using global functions, Laravel’s newer versions encourage developers to utilize facades for better organization, testability, and consistency.

The str_random() function was replaced by Str::random(), a method in the Str facade. So, when you try to use str_random() in Laravel 6 or later, you encounter the Call to undefined function error.
