HTTP requests (file_get_contents, curl) times out when calling same server listener

Description

Issue

When a script makes a HTTP call on Windows to the same host/server listener - it will time out.

Steps to reproduce:

1. Install PHP 8.2.8 for Windows
2. Create bug/test.php file with following code:

<?php
echo $_GET['say'] ?? file_get_contents('http://localhost/test.php?say=hello');

3. cd bug and start a php server in that folder: php -S localhost:80
4. Try to run the script, it will time out: php test.php

The script will time out, as the file_get_contents never responds.

Expected result

It should echo hello to the console

Further testing

This issue extends further than file_get_contents and php web server - it also affects:

• curl functions curl_exec etc not just file_get_contents
• Using php-cgi.exe and nginx on Windows with fastcgi_pass
• Also tested with Caddy web server, using proxy pass, same issue

Linux/Unix

This doesn't affect linux. Trying the above reproduction steps in Linux will echo hello. It also works as expected when using WSL/Windows Sub System for Linux.

PHP Version

PHP 8.2.8

Operating System

Windows 10

Comienza con la reproducción en Windows en bug/test.php y compara file_get_contents('http://localhost/test.php?say=hello') con los casos documentados de curl_exec. Reproduce el problema usando PHP 8.2.8 y php -S localhost:80 en Windows; después, verifica que la solicitud se complete y devuelva hello sin provocar regresiones en el comportamiento de Linux/WSL.
