bool chgrp ( $filename, $group )
Parameters: The chown() function in PHP accepts two parameters which are filename and user.
- $filename: It specifies the file whose user group you want to change.
- $group: It specifies the new user group. It can be a group name or a number.
Return Value: The chgrp() function returns true on success and false on failure.
Errors And Exception:
- The chgrp() function in PHP doesn’t works for remote files.It only works on files which are accessible by the server’s filesystem.
