Use php.ini to replace html with anything

What to include?

By including a php file using php.ini, you can replace the headers in your html with dynamic headers.

Include a php file that contains a function to replace html with different html. You include a file from your php.ini like auto_prepend_file /web/askapache.com/config.php?

php.ini

auto_prepend_file

Specifies the name of a file that is automatically parsed before the main file. The file is included as if it was called with the include() function, so include_path is used. The special value none disables auto-prepending.

auto_append_file

Specifies the name of a file that is automatically parsed after the main file. The file is included as if it was called with the include() function, so include_path is used. The special value none disables auto-appending.

Note: If the script is terminated with exit(), auto-append will not occur.
