Issue Weird PHP tempnam problem

[pegasx]

Server operating system version

Centos 7.9

Plesk version and microupdate number

Plesk Obsidian v18.0.61

Hello,

Plesk Obsidian v18.0.61
Centos 7.9
PHP 7.4.33

$tmpfile = tempnam(sys_get_temp_dir(), "LTM");
$tempHandle = fopen($tmpfile, "w+");
fwrite($tempHandle, $contents);
fclose($tempHandle);

There is no error, no warning, no notice and file name is returned as /tmp/LTMa74UOd but no file is created in /tmp.

I could not get what is the problem.

Thanks.

Hello,

If you run provided code from PHP-FPM or PHP-FastCGI from Apache, it might be affected from PrivateTmp setting of php-fpm or Apache.
