What are the potential consequences of not displaying PHP errors during script execution?

Not displaying PHP errors during script execution can lead to issues such as unnoticed bugs, security vulnerabilities, and difficulties in troubleshooting code. To solve this problem, you can enable error reporting in your PHP script by setting the error_reporting and display_errors directives in your php.ini file or using the error_reporting() function in your script.

// Enable error reporting in PHP script
error_reporting(E_ALL);
ini_set('display_errors', 1);
