PHP compression using gzip
The best way to compress PHP files is to use
auto_prepend_file
Add the filling code to a file called gzip.php
<?php
if (substr_count($_SERVER['HTTP_ACCEPT_ENCODING'], 'gzip'))
ob_start("ob_gzhandler");
else
ob_start();
?>
Then update your php.ini files as follows
auto_prepend_file= /path/to/gzip.php
you can also use a htaccess file if your server permits
php_value auto_prepend_file gzip.php
