How to cancel error prompt in php? What are the benefits?

When developing PHP projects, various errors will inevitably occur. Sometimes, these error messages not only fail to help us solve the problem, but will interfere with the development process. For this situation, the best solution is to cancel the php error prompt. In this article, we will introduce how to cancel php error prompts and the benefits of canceling php error prompts.

1. Why cancel the php error prompt

When an error occurs in the php code, php defaults An error message will be output. These error messages can be very detailed, including the code location of the error, the type of error, and so on. These error messages are useful for debugging and troubleshooting, but during development, they may interfere with the development process. Some error messages may not be serious problems, just minor problems, but in the case of error prompts, it is difficult for us to distinguish which errors need to be solved immediately.

2. Security issues

If the application contains sensitive information and the php error prompt is turned on, then this sensitive information may be exposed. For example, when a fatal error occurs in the code, PHP will output an error message, which may contain sensitive information such as database and file system paths. Developers usually enable this option when debugging, but in a production environment, this option must be disabled.
