PHP 8.0: Default error reporting is set to E_ALL
The PHP INI directive error_reporting controls which types of errors, warnings, and notices should be reported (either to screen or to logs).
In PHP 8.0, the default is changed to E_ALL.
- error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT
+ error_reporting = E_ALLThe error_reporting value expects a bit-mask, and the default value prior to PHP 8.0 was the value recommended for production: E_ALL & ~E_DEPRECATED & ~E_STRICT. This value prevented deprecation notice and strict notices from making it to error logs or screen.
In a production system, the
display_errorsvalue must be set toOff, which will hide all errors from being printed on the screen, but allows error logs to record them.
Backwards Compatibility Impact
With the default error_reporting value set to E_ALL, PHP will trigger the error handler for all PHP errors, notices, and warnings. This is a good move because it can reveal deprecation notices and that were hidden due to the previous configuration.
To bring back the same functionality as PHP 7.4:
error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT
