AddType x-mapp-php5 .php to my .htaccess file -

hi have been told hosting provider add .htaccess file enable php5

 addtype x-mapp-php5 .php 

my question is, put inside .htaccess file? @ moment looks this:

## # @version $id: htaccess.txt 14401 2010-01-26 14:10:00z louis $ # @package joomla # @copyright copyright (c) 2005 - 2010 open source matters. rights reserved. # @license http://www.gnu.org/copyleft/gpl.html gnu/gpl # joomla! free software ##   ##################################################### #  read if choose use file # # line below section: 'options +followsymlinks' may cause problems # server configurations.  required use of mod_rewrite, may # set server administrator in way dissallows changing in # .htaccess file.  if using causes server error out, comment out (add # # beginning of line), reload site in browser , test sef url's.  if work, # has been set server administrator , not need set here. # #####################################################  ##  can commented out if causes errors, see notes above. options +followsymlinks  # #  mod_rewrite in use  rewriteengine on  ########## begin - rewrite rules block out common exploits ## if experience problems on site block out operations listed below ## attempts block common type of exploit `attempts` joomla! # ## deny access extension xml files (uncomment out activate) #<files ~ "\.xml$"> #order allow,deny #deny #satisfy #</files> ## end of deny access extension xml files rewritecond %{query_string} mosconfig_[a-za-z_]{1,21}(=|\%3d) [or] # block out script trying base64_encode crap send via url rewritecond %{query_string} base64_encode.*\(.*\) [or] # block out script includes <script> tag in url rewritecond %{query_string} (\<|%3c).*script.*(\>|%3e) [nc,or] # block out script trying set php globals variable via url rewritecond %{query_string} globals(=|\[|\%[0-9a-z]{0,2}) [or] # block out script trying modify _request variable via url rewritecond %{query_string} _request(=|\[|\%[0-9a-z]{0,2}) # send blocked request homepage 403 forbidden error! rewriterule ^(.*)$ index.php [f,l] # ########## end - rewrite rules block out common exploits  #  uncomment following line if webserver's url #  not directly related physical file paths. #  update joomla! directory (just / root)  # rewritebase /   ########## begin - joomla! core sef section # rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d rewritecond %{request_uri} !^/index.php rewritecond %{request_uri} (/|\.php|\.html|\.htm|\.feed|\.pdf|\.raw|/[^.]*)$  [nc] rewriterule (.*) index.php rewriterule .* - [e=http_authorization:%{http:authorization},l] # ########## end - joomla! core sef section
