What potential error message could occur in PHP 8 when using the deprecated function?

In PHP 8, using a deprecated function will trigger a deprecation notice error message. This means that the function being used is outdated and should be replaced with an alternative to ensure compatibility and avoid issues in the future. To resolve this, you should update your code to use the recommended replacement function or method.

// Deprecated function
deprecated_function();

// Updated code using the recommended replacement function
replacement_function();
