Windows: Duplicate "Unable to load dynamic library" warning

Description

The following code:

$ php -v 
PHP Warning:  PHP Startup: Unable to load dynamic library 'ftp' (tried: ext\ftp (Das angegebene Modul wurde nicht gefunden), ext\php_ftp.dll (Falscher Parameter)) in Unknown on line 0

Warning: PHP Startup: Unable to load dynamic library 'ftp' (tried: ext\ftp (Das angegebene Modul wurde nicht gefunden), ext\php_ftp.dll (Falscher Parameter)) in Unknown on line 0

$ php -v 2>/dev/null

Warning: PHP Startup: Unable to load dynamic library 'ftp' (tried: ext\ftp (Das angegebene Modul wurde nicht gefunden), ext\php_ftp.dll (Falscher Parameter)) in Unknown on line 0

But I expected this output instead:

-> no warning in the output when stderr is redirected
-> one warning is propery redirected but it seems the very same warning is emitted a second time on stdout?

PHP Version

8.2.12

Operating System

windows11

Riproduci il comportamento su Windows 11 con php -v e php -v 2>/dev/null, confrontando l'avviso di avvio duplicato e l'output reindirizzato. Traccia l'avvio della CLI e il percorso di output dell'avviso implicati dall'esempio; il lavoro è completato quando l'avviso viene emesso una sola volta e segue il reindirizzamento di stderr come previsto.
