an HTML page in response to a user's request for a web page.\u003cbr\u003e This means that HTML pages can be tailored to individual users. \u003cbr\u003e(...) PHP is designed to work with databases like MySQL, which can store data such as the content of the pages your site displays, the products your site sells, and details about your users.\u003cbr\u003e In this book, you will learn how to use PHP to create web pages that allow users to update data stored in a database.\u003cbr\u003e\u003cbr\u003e --- p.2\u003cbr\u003e\u003cbr\u003e The PHP file creates an HTML page that informs visitors about discounts available when purchasing multiple boxes of candy.\u003cbr\u003e You can see that it does the following:\u003cbr\u003e\u003cbr\u003e ㆍ Store information in variables and arrays.\u003cbr\u003e ㆍ Use concatenation operators to combine text in variables to create a personalized greeting for your visitors.\u003cbr\u003e ㆍ Uses arithmetic operators to perform calculations that determine the price to be printed on the page. \u003cbr\u003eㆍ The new value created by the PHP interpreter is output to the HTML content of the page.\u003cbr\u003e\u003cbr\u003e Additionally, when you update the values ​​stored in variables, the page automatically reflects the new products and prices.\u003cbr\u003e\u003cbr\u003e --- p.63\u003cbr\u003e\u003cbr\u003e Websites often need to display multiple items of the same type.\u003cbr\u003e News sites publish many news articles, stores sell many products, and sites that allow users to sign up have many members.\u003cbr\u003e Each of these can be represented in code using objects. PHP uses something called a class, which is a template for creating an object that represents a type of thing.\u003cbr\u003e For example, you could create one class to represent a product and another class to represent a member.\u003cbr\u003e Each object created using a class is automatically granted the properties and methods defined in that class.\u003cbr\u003e\u003cbr\u003e --- p.144\u003cbr\u003e \u003cbr\u003eIn this chapter, we'll look at how visitors register as members of your site.\u003cbr\u003e Then, it displays a personalized page that is visible only to logged-in members.\u003cbr\u003e (...) To learn how to do this, this chapter is divided into three parts.\u003cbr\u003e\u003cbr\u003e ㆍ Membership registration on the site: A method of collecting and storing information necessary to identify individual members of the site in a database.\u003cbr\u003e Login and page personalization: How to enable members to log in, how to create pages tailored to individual members, and how to create member-only pages.\u003cbr\u003e ㆍ Updating the database without requiring the user to log in: How to update the database without requiring the user to log in first, for example, when a password needs to be updated.\u003cbr\u003e This involves addressing a new set of security requirements.\u003cbr\u003e\u003cbr\u003e --- p.604\u003cbr\u003e \u003cbr\u003eSo far in this book, the URL for each page on the sample site has been the path to the PHP file that should be executed.\u003cbr\u003e If the page had to fetch data from a database, the ID of the data was specified in the query string.\u003cbr\u003e Most websites use URLs that are more descriptive and SEO-friendly than file paths.\u003cbr\u003e When a visitor requests such a descriptive URL, the site converts the URL into a file path and tells that file what data to display.\u003cbr\u003e This is a technique called URL rewriting.\u003cbr\u003e\u003cbr\u003e --- p.636\u003cbr\u003e\u003cbr\u003e When a user logs in, the Like icon on the article page becomes a link.\u003cbr\u003e This linked file checks if the user liked the article, and adds a like if they didn't.\u003cbr\u003e If you liked it, unlike it.\u003cbr\u003e For this, a method of the Like class is called.\u003cbr\u003e\n\n\u003c\/div\u003e\n\u003cdiv\u003e --- p.654\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003c\/div\u003e \",\"\u003cdiv\u003e\u003ch5\u003e \u003cb\u003ePublisher's Review\u003c\/b\u003e\n\u003c\/h5\u003e\u003c\/div\u003e\n\u003cdiv\u003e  \u003cdiv\u003e\n\u003cb\u003eThe magic of visualizing programming concepts so they stick in your head\u003cbr\u003e\u003c\/b\u003e\u003cbr\u003e When you open a programming book, you are greeted by a torrent of complex codes filled with symbols and characters.\u003cbr\u003e Each piece of code must have some meaning, but it's not easy to know how to distinguish them.\u003cbr\u003e This book was created to beautifully resolve such beginner difficulties.\u003cbr\u003e It's colorful and fun to look at in full-color pages, and the code is visually separated to make it easy to understand right away.\u003cbr\u003e If you follow along step by step, you will be able to read and write PHP and create your own website.\u003cbr\u003e\u003cbr\u003e PHP is a constantly updated programming language used by some of the world's best websites, including Facebook, Wikipedia, and WordPress. \u003cbr\u003eThis book is designed for beginners who are new to PHP, starting with basic programming commands and moving on to a step-by-step introduction.
