Hi all.. Now I have SAMS book for PHP and mySQL but in Arabic.. so now at the moment I only want to learn things which will help me in my project.. so which lessons must I see.. and which PHP Actions will I use for that? I want to make a PHP page that reads from a mySQL Database.. This page displays two fields for the user : 1- Username. 2- Password. Now in the database there are many columns.. each one has many fields : Username, Password, Serial, Phone No., Address..Etc.. Now I want the PHP file to take the Username and Password after the user enter them in the fields and compare them with the ones inside the database.. if they are the same.. the serial field inside the database will send its value to the PHP page.. which will echo it as a variable ($var) there.. So every user has a column that has.. So which actions must I use.. and which lessons are important for me at the moment? because my project must be finnished in the comming week..
