How can error reporting and display settings impact PHP code execution?

Error reporting and display settings can impact PHP code execution by affecting how errors are displayed to the user. If error reporting is set too high, it can expose sensitive information to potential attackers. On the other hand, if error reporting is too low, it may make debugging more difficult. It is important to find a balance between displaying errors for debugging purposes and hiding them from potential attackers.

// Set error reporting level to only display errors and not warnings or notices
error_reporting(E_ERROR);

// Disable error display to prevent sensitive information leakage
ini_set('display_errors', 0);
