PHP temporary files for upload


I try to change default uploads folder because that folder doesn’t used while uploading and i noticed that main /tmp folder is used -that is wrong behavior. I try change
home/user/domains/ value upload_tmp_dir bit it doesnt change anything after apache restart . What i should do to solv this problem .?

Depends on whether you use apache_mod php / cgi / fcgi. Might need to do this in /etc/php5/apache2/php.ini or the like.

i try all of them. Now i use default fcgi.
