The .htaccess files are typically the best way to go for an Apache server. However, to answer your original question, yes you can set a php.ini file in every directory if you want. However, in order for it to work, PHP must be set to run as PHP-CGI. My guess is that you are running PHP as an Apache module.
See this link for reference on where PHP looks for php.ini and when it looks for it: http://www.php.net/manual/en/configuration.file.php
