What is the purpose of using error_reporting(E_ALL) in a PHP application?

Using error_reporting(E_ALL) in a PHP application is useful for displaying all types of errors, warnings, and notices, which can help in debugging and fixing issues in the code. It ensures that all errors are reported, even if they are not displayed by default, allowing developers to catch potential problems early on.

// Set error reporting to display all types of errors
error_reporting(E_ALL);
