How can developers modify their development environments to receive more specific error messages when encountering HTTP error 500 in PHP code?

When encountering HTTP error 500 in PHP code, developers can modify their development environments to display more specific error messages by adjusting the error reporting settings. This can be done by setting the error_reporting and display_errors directives in the php.ini file or by using the ini_set function within the PHP code itself.

// Set error reporting to display all errors
error_reporting(E_ALL);
ini_set('display_errors', 1);
