From PHP, exec('whoami') says "www-data", so I created /home/www-data and chown to www-data. file_exists with a variable still fails. Initial and future testing of !file_exists(ADS_DIR_INTERNAL) works to create the directory only once as intended, however ONLY initial creation of the file inside the directory works with move_uploaded_file. Attempting to overwrite an existing file with move_uploaded_file fails. I then tried exec('mv '.$_FILES['my_file']['tmp_name'].' '.$new_file) as well as mv -f which DOES COPY the filename of tmp_name to the correct directory ADS_DIR_INTERNAL, but keeps the tmp_name filename! It is not renamed as a true linux "mv". I assume it is some protection due to being an uploaded file.
