Since PHP 7.4, the stream php://stderr is giving me a PHP notice "Bad file descriptor".

Everything is working fine with PHP 7.3. If i switch to mod_apache I don't have the notice. Also, the notice isn't happening if I run my script directly from the command line.

My script is :
$fp = fopen('php://stderr', 'w');
fwrite($fp, "test\n");

The result is :
Notice: fwrite(): write of 5 bytes failed with errno=9 Bad file descriptor in D:\htdocs\test_code\74.php on line 18

Thanks,

Congratulations you found a bug in PHP 7.4!

Code:

error_reporting(E_ALL);
ini_set('display_errors','On');
$fp = fopen('php://stderr', 'w+');
var_dump($fp);
fwrite($fp, "test\n");


the var_dump shows that it is a valid stream.
