php.ini error_reporting option messes with phpcs plugin for vscode

I have a vscode plugin that uses phpcs for linting.

I get this error:

phpcs: Unknown error ocurred. Please verify that C:\Users\David\AppData\Roaming\Composer\vendor\bin\phpcs --report=json -q --encoding=UTF-8 --standard=dev/setup/codesniffer/ruleset.xml --error-severity=5 --warning-severity=5 --stdin-path=C:\xampp7\htdocs\person.class.php - returns a valid json object.

If I run the command on the terminal with error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT I get this output:

{"totals":{"errors":0,"warnings":0,"fixable":0},"files":{"C:\\xampp7\\htdocs\\person.class.php":{"errors":0,"warnings":0,"messages":[]}}}

If I run the command on the terminal with error_reporting = E_ALL I get this output:

Xdebug: [Config] The setting 'xdebug.trace_output_dir' has been renamed, see the upgrading guide at https://xdebug.org/docs/upgrade_guide#changed-xdebug.trace_output_dir (See: https://xdebug.org/docs/errors#CFG-C-CHANGED)
{"totals":{"errors":0,"warnings":0,"fixable":0},"files":{"C:\\xampp7\\htdocs\\person.class.php":{"errors":0,"warnings":0,"messages":[]}}}

I know I can just fix xdebug.trace_output_dir but something else will pop up in the future.

How can I fix this? Isn't display_errors = Off to avoid this kind of stuff?

Edit:

I can point the plugin to the executable phpcs.bat

if "%PHP_PEAR_PHP_BIN%" neq "" (
    set PHPBIN=%PHP_PEAR_PHP_BIN%
) else set PHPBIN=php

"%PHPBIN%" -d display_errors=off "%~dp0\phpcs" %*

Here I can set options like -d display_errors=off which I already have on php.ini

Here's the relevant options:

error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT
error_reporting = E_ALL
display_errors = Off
display_startup_errors = Off
log_errors = On
log_errors_max_len = 1024

This shows the Xdebug error.

error_reporting = E_ALL
error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT
display_errors = Off
display_startup_errors = Off
log_errors = On
log_errors_max_len = 1024

This does not.

Could it be that xdebug is printing to STDOUT instead of STDERR?

Edit2:

For now I'll make do with this php -d error_reporting=22527 -r "echo E_ALL & ~E_DEPRECATED & ~E_STRICT;"

Edit3:

Errors again.

php -i | grep "error"

display_errors => STDERR => STDERR
display_startup_errors => On => On
error_append_string => no value => no value
error_log => C:/xampp7\php\logs\php_error_log => C:/xampp7\php\logs\php_error_log

php -d error_reporting=22527 -d display_errors=off -i | grep "error"

display_errors => Off => Off
display_startup_errors => On => On
error_append_string => no value => no value
error_log => C:/xampp7\php\logs\php_error_log => C:/xampp7\php\logs\php_error_log

xdebug.force_display_errors => Off => Off

However if I do this: php -d error_reporting=22527 -d display_errors=off "C:\Users\david\Documents\PHP_CodeSniffer\bin\\phpcs" --version

I get errors:
