What are the potential drawbacks of using workarounds like suppressing errors with "@" when dealing with PHP functions like session_start()?

When using workarounds like suppressing errors with "@" in PHP functions like session_start(), it can lead to issues such as hiding important error messages that could help diagnose and fix problems in the code. It can also make debugging more difficult and potentially introduce security vulnerabilities if errors are not properly handled.

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);

session_start();
// Rest of the code
?>
