Compression of index.php for pagespeed

    I've got a client who's obsessing about pagespeed scores. I've told her it's about as useful as a diesel emission test but I can cheat the results if that's what she wants!

    However I would like to understand compression. I was running without compression. I've now switched compression on and all warnings have gone except on the root which I'm assuming is index.php.

    The code I've added to .htaccess is

    <IfModule mod_deflate.c>
  # Compress HTML, CSS, JavaScript, Text, XML and fonts
  AddOutputFilterByType DEFLATE application/javascript
  AddOutputFilterByType DEFLATE application/rss+xml
  AddOutputFilterByType DEFLATE application/vnd.ms-fontobject
  AddOutputFilterByType DEFLATE application/x-font
  AddOutputFilterByType DEFLATE application/x-font-opentype
  AddOutputFilterByType DEFLATE application/x-font-otf
  AddOutputFilterByType DEFLATE application/x-font-truetype
  AddOutputFilterByType DEFLATE application/x-font-ttf
  AddOutputFilterByType DEFLATE application/x-javascript
  AddOutputFilterByType DEFLATE application/x-httpd-php
  AddOutputFilterByType DEFLATE application/x-httpd-fastphp
  AddOutputFilterByType DEFLATE application/xhtml+xml
  AddOutputFilterByType DEFLATE application/xml
  AddOutputFilterByType DEFLATE font/opentype
  AddOutputFilterByType DEFLATE font/otf
  AddOutputFilterByType DEFLATE font/ttf
  AddOutputFilterByType DEFLATE image/svg+xml
  AddOutputFilterByType DEFLATE image/x-icon
  AddOutputFilterByType DEFLATE text/css
  AddOutputFilterByType DEFLATE text/html
  AddOutputFilterByType DEFLATE text/javascript
  AddOutputFilterByType DEFLATE text/plain
  AddOutputFilterByType DEFLATE text/xml

  # Remove browser bugs (only needed for really old browsers)
  BrowserMatch ^Mozilla/4 gzip-only-text/html
  BrowserMatch ^Mozilla/4\.0[678] no-gzip
  BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
  Header append Vary User-Agent
</IfModule>


    How to I get compression to work on index.php?

      Never tried it, I don't use apache any more, I use nginx. I would suggest looking into: Statcache: http://modx.com/extras/package/statcache. When set up correctly you don't need to compress any PHP file as the server will serve HTML files once it is cached/ran once. This will be the fastest you can make your server to client response time. Statcache docs: https://github.com/opengeek/statcache/wiki

        You are not serving .php files. The index.php file is passed on to PHP (whether as an Apache module or a CGI/FastCGI process) to process directly on the server, and it is its output that is returned to the web server and served as the request response. If the web server does somehow compress a .php file before passing it on to the PHP program, it would only slow things down as the PHP program has to expand it before it can process it.

        Compressing images and PDF files is an exercise in redundancy, they are already compressed all by themselves. You're just putting an extra load on the server to no purpose.
