phpMyAdmin

Hi guys, I need some help using the phpMyAdmin, I'm trying to create a table with three fields, one for the indexing of the database, the second for the logins and the third for the password. I get the following doubts: On the table of the phpMyAdmin there are the following fields: A field for the name of the field. A field for the kind of information that will be stored in the field (TINYINT,DOUBLE,TEXT...) A field for the size of the field. A field for the atributes of the field (BINARY, UNSIGNED, UNSIGNED ZERO FILL) A field for the null option (NULL, NOT NULL). A field for an information that I don't know... A field for the Extra(AUTO_INCREMENT). A selectable field named primary(check it or not). A selectable field named index(check it or not). A selectable field named unique(check it or not). A selectable field named Fulltext(Check it or not). The information that I would need would be what are the configurations that I have to put in each of these fields. And also I would need to know a php script to access the fields, and write to new fields. Thanx, Rodrigo
