How can I use PHP to create login web pages?

Indeed, php is easy for logins and many of the frameworks like apphp allow you to creat captchas and other login methods very easily.

Agree with of Mr.Michael McLean  opinion . Thanks

create table in mysql( or any other database) to store user name and password. Then in form execute a select query to check if a record exists in databse corresponding to the user name and password entered by user in textboxes. If record exists then register the session in that user name and navigate the user to the next page. If no record exists then display an error message to the user. When the user logs out, destroy that session that was earlier registered.
