PHP max_filesize

I am trying to up the maximum uploadable file size to my website. I have tried doing this through .htaccess, but run into some problems.

If I use

AddHandler application/x-httpd-php .php
php_value post_max_size 150M
php_value upload_max_filesize 150M
php_value memory_limit 250M

then I can successfully upload larger files (but nowhere near the 150 MiB you might expect) but it seems to use PHP 4.4.7. On the other hand,

AddHandler phpFive .php
Action phpFive /cgi-system/php5.cgi
php_value post_max_size 150M
php_value upload_max_filesize 150M
php_value memory_limit 250M

keeps me at the latest version of PHP, but does not seem to alter the size.

Any ideas?!

Cheers!

Increase the values in your php.ini (as opposed to the .htaccess method).
