Aide script php a rentrer les donnée mysql

voila je veux céer un site autoqurf ,j'ai donc réussi a avoir un srcipt gratuit .
maintement il faut que je rentre mes donnée mysql

le probléme c'est que je c'est pas comment nmit prendre car j'ai essayer de le configurer mais sa ne marche pas

Explication
j'ai donc activer ma basse mysql de mon hebergeur (ok)
j'ai mes identifiant (serveur ,user,password,base de donnée)

le souci est que je ne c'est pas ou je doit les mettre exactement car j'ai plusieur fichiers

les fichiers .php : auth, contest, index, var, report, signup, urltest, bar, hedfoot, activate, lost, regmail,target, view4credits

Mes questions : est-ce que vous savez quel fichiers dois-je changer?
est-ce que je n'est qu'un fichiers a changer ou tout ceux qui on la fonction mysql_connect($localhost, $user, $password);
mysql_select_db($db_nane);

puis-je vous montrer l'interrieur du ou des fichiers que je dois changer?
