ftp_close() function returns warning while trying to close SSL connection.
Exact stdout:
ftp_close(): SSL_read on shutdown

I run following testscript with latest docker php7-cli image.
docker run --rm -v ./code/:/code/ php:7-cli php /code/test.php

Test script:
$ftp_conn = ftp_ssl_connect('server');
$ftp_login = ftp_login($ftp_conn, 'user', 'pass');
echo ftp_pwd($ftp_conn);

Expected result:
print working directory without any error

Actual result:
print working directory and warning message on ftp close.

The respective code[1] looks fishy.  Shouldn't the
php_error_docref() be inside the if statement?

Likely a false alarm, see

I can't reproduce this here. But my setup is fairly limited and I'm running the latest releases only.

What's the full error message? "SSL_read on shutdown" is truncated. There should be a readable system/openssl error message + corresponding error number.

We are also seeing this issue. It also involves ftp_put, instead of ftp_close. It is happening since the upgrade to 7.1.24 and seems therefore related to this issue.

PHP Warning:  ftp_fput(): SSL_read on shutdown: Connection reset by peer (104)

PHP Warning:  ftp_fput(): Data channel timed out due to not meeting the minimum bandwidth requirement.

PHP Warning:  ftp_close(): SSL_read on shutdown: Success (0)
