PHP.ini custom settings through htaccess

I'm confused by this ini list in the PHP Manual: http://www.php.net/manual/en/ini.list.php

I want to set some custom php.ini values through htaccess, but which one of these commands is not going to work?

php_value upload_max_filesize 1M

php_value max_execution_time 3

php_value max_input_time 3

php_value memory_limit 2M

php_value post_max_size 1M

php_value open_basedir "/scripts"

php_flag allow_url_fopen 0

php_flag allow_url_include 0

php_flag file_uploads 0
