PHP + HTML = complete login / user application?

Question

My current goal is to create a website which has a complete sign up / create account and login application. Which can not only carry out this process but also store the login information securely and indefinitely. Is HTML and PHP enough to carry out this process to its entirety? Where does sql fit in? Do I need sql or another language to complete this? Thanks!

Answer 1

Yes, in most cases are users names and their passwords stored in database, so you have to use sql to check login (and many next operations of users). Dont affraid, the sql commands are called from php command, like:
$ses_sql=mysql_query("select username from login where username='$user_check'", $connection);
But it can be a seiouzly problematic, because a right login is a matter of secure of your application. So, study it in PHP documentation i deep.

Answer 2

You can do it in several languages like advanced Java, .Net languages . you can able to store the login details in secured databases too.
