Possibly superfluous backslash in proc_open() escaping on Windows

[cmb69]

Description

The following code:

<?php
proc_open(["test.bat", "\"&notepad.exe"], …);

passes "test.bat" ^"\^"^&notepad.exe^" to CreateProcess(). The backslash appears to be superfluous.

PHP Version

PHP 8.2

Operating System

Windows

Is this bug fixed in version 8.4.10?

I don't think this is fixed yet. Do you face any issues with the behavior?
