7 building personalized web apps

Remember me? What’s your name again? Johnson, right. Well, I’m showing no record of you, Mr. Jackson. Are you sure you signed up for a warranty on your cryogenic storage cell? Oh, I see, so you’re calling from inside your cell right now. And what was your name again?

No one likes to be forgotten, especially users of web applications. If an application has any sense of “membership,” meaning that users somehow interact with the application in a personal way, then the application needs to remember the users. You’d hate to have to reintroduce yourself to your family every time you walk through the door at home. You don’t have to because they have this wonderful thing called memory. But web applications don’t remember people automatically—it’s up to a savvy web developer to use the tools at their disposal (PHP and MySQL, maybe?) to build personalized web apps that can actually remember users.

a good mismatch is hard to find

They say opposites attract It’s an age-old story: boy meets girl, girl thinks boy is completely nuts, boy thinks girl has issues, but their differences become the attraction, and they end up living happily ever after. This story drives the innovative new dating site, Mis-match.net. Mismatch takes the “opposites attract” theory to heart by mismatching people based on their differences.

Problem is, Mismatch has yet to get off the ground and is in dire need of a web developer to finish building the system. That’s where you come in. Millions of lonely hearts are anxiously awaiting your completion of the application. don’t let them down!

Sidney loves reality TV, yoga, and sushi, and is hoping for a successful mismatch.

I can’t wait to find my perfect mismatch.

Personal web applications thrive on personal information, which requires users to be able to access an application on a personal level.

Sidney Kelsow Female 1984-07-19 Tempe, AZ

Johan loves professional wrestling, weightlifting, and Spam, and is excited about anyone who’ll reply to him.

Mismatch users need to be able to interact with the site on a personal level. For one thing, this means they need personal profiles where they enter information about themselves that they can share with other Mismatch users, such as their gender, birthdate, and location. 346 Chapter 7

building personalized web apps

Mismatch is all about personal data So Mismatch is all about establishing connections through personal data. These connections must take place within a community of users, each of whom is able to interact with the site and manage their own personal data.

Авторы — Линн Бейли, Майкл Моррисон

Книга Линн Бейли и Майкла Моррисона «Изучаем PHP и MySQL» из серии «Head First» предназначена для тех, кто желает двигаться дальше создания простых НТМL-страниц, хочет изучить, понять и запомнить, как использовать РНР и MySQL для разработки веб-приложений. Книги данной серии отличаются простотой изложения, многочисленными примерами и использованием большого количества иллюстраций. Эту книгу можно назвать учебным пособием, но справочником она не является. Начинается книга с изучения простых проrраммных решений и основных приемов работ с базами данных. Затем рассматриваются более сложные функции РНР и запросы MySQL, а в самом конце описывается решение наиболее сложных задач. Хотя очень важно создавать приложения, которые позволяют пользователям добавлять в него данные и извлекать их, однако прежде чем вы сможете делать это, вам необходимо разобраться с синтаксисом и РНР, и MySQL. Поэтому в книге даются выражения РНР и MySQL, которые вы можете проверить на практике.

В книге не рассматриваются ВСЕ выражения, функции, ключевые слова и запросы РНР и MySQL. Эту информацию вы сможете найти в соответствующих справочниках. Описываются лишь те из них, которые вам необходимо знать и которые вы будете использовать в 95% времени.

Материал книги основан на использовании РНР версий 5 или 6 и MySQL версий 5 или 6.
