What potential issues can arise when using error_reporting(E_ALL) in PHP scripts?

When using error_reporting(E_ALL) in PHP scripts, potential issues can arise from displaying sensitive information such as file paths, database credentials, or other internal details to users if an error occurs. To solve this issue, it's recommended to use error_reporting(E_ALL & ~E_NOTICE) to suppress notices and only display more critical errors.
