Php 8.1 with Phalcon

[euazzo]

I need to create a new docker image to update an application to php 8.1.
However, I encounter a compatibility problem between php 8.1 and the Phalcon extension.
The current configuration is Phalcon 3.4.1 with PHP 7.11.

`FROM php:X.X-apache
MAINTAINER IT Department - Consulcesi Tech SA

ARG PHALCON_VERSION=XXX
ARG PHALCON_EXT_PATH=phpX/64bits

RUN set -xe &&
# Compile Phalcon
curl -LO https://github.com/phalcon/cphalcon/archive/v${PHALCON_VERSION}.tar.gz &&
tar xzf ${PWD}/v${PHALCON_VERSION}.tar.gz &&
docker-php-ext-install -j $(getconf _NPROCESSORS_ONLN) ${PWD}/cphalcon-${PHALCON_VERSION}/build/${PHALCON_EXT_PATH} &&
# Remove all temp files
rm -r
${PWD}/v${PHALCON_VERSION}.tar.gz
${PWD}/cphalcon-${PHALCON_VERSION}
`
The error is on the build phase at the Phalcon run section. I also tried with different VERSION and EXT_PATH.
It's possible? What version/configuration should I set to get an image with php8.1 and Phalcon?

Only Phalcon 5 is compatible with PHP 8. This is currently in beta phase.

What is it the highest PHP version supported by the latest stable version (4.1.3) of Phalcon?
When will the stable version of Pahlcon 5 be released?

7.4 is the highest version of PHP you can use with Phalcon 4.

As for Phalcon 5, it is currently v5.0.0beta3. I don't think there is a specific date, i guess as soon as all major defects are fixed.
