Unsupported PHP 8 command in Magento

[michalrostek]

Preconditions (*)

 

1. Magento 2.4.3 EE
2. PHP 7.4

Steps to reproduce (*)

1. There is a PHP 8 (str_contains) command in \Magento\Framework\Filesystem\Directory\DenyListPathValidator:74 which is not officially supported yet ... so we have such errors during installation:

{{PHP Fatal error: Uncaught Error: Call to undefined function Magento\Framework\Filesystem\Directory\str_contains() in <...>/magento/vendor/magento/framework/Filesystem/Directory/DenyListPathValidator.php:74

This file (DenyListPathValidator) is initialized in \Magento\Framework\Filesystem\Directory\WriteFactory.php which may affect not only the above case

Expected result (*)

PHP 7 command, instead of PHP 8

Actual result (*)

PHP 8 command
