php-fpm clear_env yes does not clear environment

Description

Description

The following code:

PHP-FPM
with clear_env = yes

<?php

var_dump( filter_input( INPUT_SERVER, 'REQUEST_TIME_FLOAT' ) );
var_dump( $_SERVER['REQUEST_TIME_FLOAT'] );

var_dump( filter_input( INPUT_SERVER, 'REQUEST_TIME' ) );
var_dump( $_SERVER['REQUEST_TIME'] );

Resulted in this output:

NULL
float(1737560728.0001)
NULL
int(1737560728)

But I expected this output instead:

NULL
NULL
NULL
NULL

These are the only 2 documented in https://www.php.net/manual/en/reserved.variables.server.php with that behavior

The same also happens for HOME and USER for example

It seems this is partially bc of https://github.com/php/php-src/issues/17543#issuecomment-2614521724

Since https://github.com/php/php-src/issues/17543 was marked not a bug, then this, which is the opposite case has to be a bug, otherwise it's completely arbitrary.

PHP Version

8.4

Start with the PHP-FPM clear_env setting and the manual page for reserved server variables, then read the linked issue #17543 and its referenced comment. Compare the documented behavior with the reported PHP 8.4 results for REQUEST_TIME_FLOAT, REQUEST_TIME, HOME, and USER; done requires an agreed resolution for what the documentation should state.
