The error_reporting function is used to set the current error reporting level. In PHP, the error reporting level determines which types of errors will be reported and displayed on the page. The usage of this function is as follows:

error_reporting(level);

One of the constants that the level parameter can be is:

  1. E_ALL: display all errors and warnings (default setting)
  2. E_ERROR: Fatal error displayed
  3. Display warning: E_WARNING
  4. E_NOTICE: Displays a notification message.
  5. E_PARSE: Display parse error
  6. E_STRICT: display errors according to strict standards.
  7. E_DEPRECATED: displays a warning for deprecated functions.

You can set multiple error reporting levels by connecting several constants using logical operators (such as |). For example, if you want to display all errors, warnings, and notices, you can use the following statement:

error_reporting(E_ALL | E_NOTICE | E_WARNING);

During the debugging and development phases, setting the error reporting level to E_ALL can help developers identify and address potential issues. In a production environment, it is typically recommended to set it to an appropriate level to avoid exposing sensitive information to users.
