Disable magic_quotes_gpc in a .htaccess file

Hi All,

How do I disable magic quotes via .htaccess?

I put the following file in my webroot, but it does not disable
magic_quotes_gpc (according to phpinfo(), both the local and master value
are still "on")

<IfModule mod_php4.c>
php_value upload_max_filesize 8M
php_value magic_quotes_gpc 0
</IfModule>


The change to upload_max_filesize works (master is 2M, local value is 8M,
according to phpinfo())

Guess I've got something wrong.  Any help?
