Exclusive locks are not supported for this stream `php://stdout`

Description

I wonder why the file_put_contents emitts a Exclusive locks are not supported for this stream error and putting the very same stream into stream_supports_lock does not return false, but also errors.

The following code:

<?php

var_dump(stream_supports_lock("php://stdout"));

file_put_contents(
    "php://stdout",
    "x",
    FILE_APPEND | LOCK_EX,
);

Resulted in this output:

$ php test.php 
PHP Fatal error:  Uncaught TypeError: stream_supports_lock(): Argument #1 ($stream) must be of type resource, string given in C:\dvl\Workspace\phpunit\test.php:3
Stack trace:
#0 C:\dvl\Workspace\phpunit\test.php(3): stream_supports_lock()
#1 {main}
  thrown in C:\dvl\Workspace\phpunit\test.php on line 3

  thrown in C:\dvl\Workspace\phpunit\test.php on line 3

But I expected this output instead:

$ php test.php 
bool(false)
PHP Warning:  file_put_contents(): Exclusive locks are not supported for this stream in C:\dvl\Workspace\phpunit\test.php on line 5

Warning: file_put_contents(): Exclusive locks are not supported for this stream in C:\dvl\Workspace\phpunit\test.php on line 5

might be a windows only error, because 3v4l.org does not report the same error

Empieza reproduciendo el ejemplo en Windows con PHP 8.2.12 y compara stream_supports_lock("php://stdout") con file_put_contents(..., FILE_APPEND | LOCK_EX). Comprueba el comportamiento con respecto al resultado booleano esperado y a la advertencia; después, verifica que el mismo caso ya no provoque un TypeError y siga indicando que no se admiten bloqueos exclusivos.
