ඔයාල කැමතිද මේ වගේ ලොගින් සිස්ටම් එකක් තනියම හදල බලන්න.
1. මේකට database හා php දැනුම ඕනේ ටිකක්. ඉස්සල්ලම php, server හා database පරිගණකයේ ස්ථාපනය කරගත යුතුය.
sever එක දාගෙන නැති අය මෙතනින් ගිහින් දාගන්න හැටි බලන්න.
එක පාර wamp වගේ server එකක් දාගන්නත් පුළුවන්.
ඉස්සල්ලම browser එකේ http://localhost/phpmyadmin කියල ගහන්න.
database>create new database ගිහිල්ල test කියල database එකක් හදන්න. collation කියන එකට utf8 _genaral _ci silect කරන්න.
ඒකේ members කියල table ක් හදන්න. ඒකේ id, username, password, email කියල fields 4ක් හදන්න. id කියන ඒකේ type 1 INT, length එක 5, collation utf8 _genaral _ci දෙන්න. අනිත් fields වල type 1 VARCHAR, length එක 50, collation utf8 _genaral _ci දෙන්න.
