Hello!!

I wan't your opinion for a optimization for PHP code. The ideia is when I insert a new service in the administration, the service is inserted in DB and is writed in a file with a number and the name. A webdesigner, that doesn´t understand PHP, with base on file, must reference the number of the service in HTML code, in some way that it goes at DB looking for the reference of a pdf file for show in a page. I have a PHP function ready, but how can i put the numbers in it,with the reference may be in XML? More Ideias??
