How to give permission to execute a PHP script?

Question

linux

There is a PHP script that generates an xml file. When calling the DomDocument - save class method, a warning pops up:

Warning: DOMDocument::save(rss.xml): failed to open stream: Permission denied in /home/roman/server/site.com/RSS/RSS_create.php on line 31

I tried to give permission to the script with chmod 777 and chmod +x , it didn't help. Tell me what's the problem?

Answer 1

There is no write access to the folder where the script writes.
