Because whatever the default is,its not recognized, or unusable by what i install.

My host by default has upload_tmp_dir as => no value => no value, and as you can expect php.ini is read only on shared hosting, but i need to change it. So i have read a bit on this and i have seen people saying about doing it in .htaccess or creating a separate php.ini in your website's root and somehow making it recursive and telling php to use it for your site from .htaccess, but i am really new to all this so i dont even know how to begin doing that or even if it makes any sense in practice. I even talked to my host about this, and they didn't have any idea and said they never heard of anything like this. So any help for a man that just lost 3 days trying to solve this? Thanks to anybody that might at least try to help!
