Should You Use PHP's `@` Operator for Error Suppression?

Suppressing Errors with the '@' Operator in PHP

The use of the error suppression operator (@) in PHP can be a controversial topic. Some developers argue for its occasional validity, while others strictly advise against it.

Arguments Against Using '@'

According to the popular opinion, the use of '@' should be avoided under all circumstances. Its primary drawback lies in its ability to conceal errors that may emerge in the future due to changes in the code or environment. This can result in debugging nightmares, as the suppressed error no longer provides any indication of its occurrence.

Alternatives to '@'

Instead of resorting to error suppression, it is recommended to handle the actual error itself. This allows for the implementation of specific error handling mechanisms based on the nature of the error.

For non-fatal errors, setting up an error handler can redirect error messages to a centralized point of handling. This way, errors can be logged and displayed to developers while being hidden from end users.

For fatal errors, it is recommended to disable display_errors in the PHP configuration and rely on error logging instead. Advanced error handling techniques, such as utilizing the shutdown function, can be employed to capture and log even fatal errors.

Conclusion

While the error suppression operator (@) may seem like a convenient solution for concealing errors, it should be strongly discouraged due to its negative implications on debugging and error management. Modern alternatives provide more effective and reliable mechanisms for handling errors in a robust manner.
