This is related to bug #32708

There must be a way to set tmp-file creation of this functions, but setting TMPDIR environment variable doesn't work. I don't want to include /tmp dir in open_basedir directories.



Reproduce code:
---------------
<?php
putenv('TMPDIR=/hosting/clients/xxx.com/httpd/tmp');

echo getenv('TMPDIR');

// set up basic connection
$conn_id = ftp_connect("xxx.com");

// login with username and password
$login_result = ftp_login($conn_id, "xxx", "xxx");

// get the file list for /
$buff = ftp_rawlist($conn_id, '/');

// close the connection
ftp_close($conn_id);

// output the buffer
var_dump($buff);
?>

Expected result:
----------------
listing of files

Actual result:
--------------
/hosting/clients/xxx.com/httpd/tmp
