Question

I have a file in my project folder.How i can i give file write permission using php.I used this code

chmod($file,0777);

But it giving an error

Warning: chmod() [function.chmod]: Operation not permitted 

The file is created by another user.Is their any way to do this .Thanks in advance

Answer 1

This happens because PHP does not have rights to do the change. The user under which PHP runs is usually the web server’s user and different from the user you use to add files.

You generally only do chmod on files created with PHP. To be able to do this on other files you need to change the owner (chown).
