error_reporting level cannot be changed in the fpm image

[przemub]

Hi,

I'm very happily using [email protected] image for hosting a Wordpress website.

An issue is my logs are polluted with E_NOTICE messages that I'd like to turn off. This is what they look like:

root-1  | NOTICE: PHP message: All-in-One Event Calendar: Twig_Parser::addImportedSymbol(): Implicitly marking parameter $node as nullable is deprecated, the explicit nullable type must be used instead @ /root/wp-content/plugins/all-in-one-event-calendar/vendor/twig/Parser.php:289 #8192
root-1  | NOTICE: PHP message: All-in-One Event Calendar: Using ${var} in strings is deprecated, use {$var} instead @ /root/wp-content/plugins/all-in-one-event-calendar/vendor/lessphp/lessc.inc.php:1215 #8192
root-1  | NOTICE: PHP message: All-in-One Event Calendar: Using ${var} in strings is deprecated, use {$var} instead @ /root/wp-content/plugins/all-in-one-event-calendar/vendor/lessphp/lessc.inc.php:1560 #8192
root-1  | NOTICE: PHP message: PHP Warning:  Cannot modify header information - headers already sent in /root/wp-content/plugins/membership/app/controller/class-ms-controller-plugin.php on line 99

I made a child image with a Dockerfile like this:

FROM php:8-fpm

ADD https://github.com/mlocati/docker-php-extension-installer/releases/latest/download/install-php-extensions /usr/local/bin/
RUN chmod +x /usr/local/bin/install-php-extensions && sync && \
    install-php-extensions gd mysqli pdo pdo_mysql

RUN mv "$PHP_INI_DIR/php.ini-production" "$PHP_INI_DIR/php.ini"
RUN echo "cgi.fix_pathinfo=0;" >> $PHP_INI_DIR/conf.d/szkolaszermierki.conf
RUN sed -i 's/^error_reporting = .*$/error_reporting = E_ALL \& ~E_NOTICE \& ~E_DEPRECATED \& ~E_STRICT/' "$PHP_INI_DIR/php.ini"

error_reporting seems to be correctly set as phpinfo() outputs error_reporting = 22519, which is equal to E_ALL \& ~E_NOTICE \& ~E_DEPRECATED \& ~E_STRICT when checked in the shell. Nevertheless I still get the messages. Any idea why?

PHP version is 8.4.1, host is Ubuntu 22.04, Docker engine is 27.4.0.

Looks like these notices are not E_NOTICE but rather warning and user_deprecated

Hi @LaurentGoderre, thanks for the suggestion!

I tried turning off everything with error_reporting = 0 but interestingly, it changed nothing as well. I noticed that all messages are logged with NOTICE: as well:

[16-Dec-2024 20:17:29] NOTICE: fpm is running, pid 1
[16-Dec-2024 20:17:29] NOTICE: ready to handle connections
NOTICE: PHP message: All-in-One Event Calendar: Ai1ec_Loader::_cache(): Implicitly marking parameter $entries as nullable is deprecated, the explicit nullable type must be used instead @ /root/wp-content/plugins/all-in-one-event-calendar/lib/bootstrap/loader.php:123 #8192

I suppose error_reporting is overridden by something somewhere? I checked php-fpm config files but I found nothing interesting there.

I raised log_level to error in /usr/local/etc/php-fpm.conf while keeping error_reporting at 0. Deprecation PHP messages remained but without NOTICE prefix.

WordPress does modify error_reporting at runtime, but I'm not sure if any of it is related:

https://github.com/search?q=repo%3AWordPress%2FWordPress%20error_reporting&type=code

(perhaps that plugin / some other plugin does also?)

That being said, this isn't really an issue with the PHP image we maintain. 😅
