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

Research direction

Reproduce the PHP 8.2 example on Windows and inspect the proc_open() argument escaping before the CreateProcess() handoff. Compare the generated command with the reported output and determine whether the backslash is superfluous. Done means the behavior is resolved or documented with regression coverage for this case.
