PHP Login Script with Remember Me Feature

in PHP added by goodphptutorials, on 23/8/2006 account logon mysql signup user authentication

I just started programming with PHP and MySQL this week and the first script I wanted to write was a login script. I wanted to include the popular "Remember Me" feature seen on a lot of websites that basically keeps users logged into the website, even after they've closed the browser so that the next time they come, they won't have to login again manually.

Storage and re-use of images using PHP/GD - Part 2

in PHP added by goodphptutorials, on 23/8/2006 gd image storage media web publishing

We could feed that system our images once, and retrieve them later in many different formats. In this article, we will write some scripts that come close to this ideal system. PHP and the GD-library will provide us with an easy method of uploading, searching and publishing our images.

Yet still the practice of using objects in PHP remains a bit of a lost art ? you're more likely to find an application with a bunch of functions than objects.
