- Hidden input fields which allow passing information between pages without the user seeing it but could be viewed in the page source code.
- The <div> tag which defines sections and supports formatting with CSS.
- The <span> tag which groups inline elements and supports styling but provides no visual change on its own.
- An assignment to dynamically generate form controls across three pages based on user input.
AJAX is a technique for building fast, dynamic web applications by exchanging small amounts of data with the server behind the scenes without reloading the entire web page. It uses a combination of technologies including JavaScript, XML, HTML and CSS to retrieve data from the server asynchronously in the background without interfering with the display and behavior of the existing page. The XMLHttpRequest object plays a key role by providing a way for JavaScript to make HTTP requests directly to a web server, enabling asynchronous data retrieval and manipulation of page elements without reloading.
A user interface is a link between a user and a computer that allows them to communicate. There are two main types of user interfaces: command driven and graphical user interfaces (GUI). Command driven interfaces are text-based and require the user to type commands, while GUIs use graphical elements like icons and menus to provide a more intuitive interface. While command driven interfaces are faster and use less resources, GUIs are generally easier to use and more visually appealing.
This document discusses interfaces and abstract classes in PHP. Interfaces define a contract that classes can implement, requiring them to contain the declared methods but not defining method bodies. Abstract classes can contain method bodies but require subclasses to override any abstract methods. The document provides examples of an interface for a database driver, an abstract report generator class, and a MySQL driver class that implements the interface and extends the abstract class.
SQL is a non-procedural language used to create and manipulate relational databases. It allows users to define database schemas through DDL commands like CREATE and ALTER, manipulate data through DML commands like INSERT, UPDATE and DELETE, and provide security through DCL commands. Key SQL concepts covered include data types, constraints, creating and modifying tables, and performing CRUD operations.

The document discusses database normalization. It begins by explaining the first normal form (1NF), which requires data to be atomic and for each row to have a unique primary key. An example employee database is provided, and steps are taken to transform it into 1NF by creating individual rows for each employee. The document then covers the second normal form (2NF), which requires the database to be in 1NF and for non-key attributes to depend on the whole primary key. To achieve 2NF, repeating groups like city and state are extracted into separate tables. Finally, the third normal form (3NF) is discussed, requiring attributes to depend transitively on the primary key. An order database is used as an example, and
An entity-relationship diagram (ERD) is a graphical representation that depicts the entities and relationships within an information system. An ERD shows a database's entities and the relationships between entities in a symbolic, visual way. It documents a project, clarifies features, and provides a basis for development options. Key components of an ERD include entities, relationships, attributes, and cardinality. The steps to create an ERD are to identify entities, determine interactions, analyze the nature of interactions, and draw the diagram. A good ERD model is simple, non-redundant, and flexible to adapt to future needs.

The SELECT statement is used to retrieve data from one or more tables. It allows you to select specific columns, rows, and expressions. The general syntax includes keywords like SELECT, FROM, WHERE, and clauses for filtering, sorting, grouping, and joining results. Examples demonstrate how to select all data, particular rows and columns, use aliases, DISTINCT, comparison operators, patterns, ranges, and handle NULL values.
The document discusses different types of joins in MySQL including inner joins, outer joins, cross joins, equi joins, natural joins, and self joins. Inner joins return rows that match between two tables, while outer joins return all rows from one or both tables even if they don't match. Cross joins perform a Cartesian product between tables, equi joins combine tables based on common columns, and natural joins compare columns with the same name. Self joins allow retrieving related records from a single table that references itself.
This document discusses various PHP functions for manipulating dates and times - getdate(), strtotime(), and date().
Getdate() returns an associative array of date/time values for a given timestamp. Strtotime() parses an English textual datetime into a Unix timestamp. Date() formats a timestamp based on a format string, with different format specifiers for dates, times, years, months, and more. Examples are provided for using these functions.
This document provides an overview of object-oriented programming (OOP) concepts in PHP, including classes, objects, properties, methods, inheritance, and magic methods. It defines classes as blueprints that define an object's structure and relationships, while objects are instances built from those blueprints. Properties and methods are used to store data and perform actions within classes. Inheritance allows one class to inherit properties and methods from another. Magic methods like __construct() and __destruct() are automatically called during object instantiation and destruction. Later sections demonstrate class inheritance, overwriting inherited properties and methods, and using multiple class instances.
This document discusses string functions in PHP programming. It defines what a string is, including that it is a collection of characters used to represent text. It then proceeds to describe several PHP functions for working with strings, including chr() and ord() to get character codes, strlen() to get string length, substr() to extract parts of a string, and trim() to remove whitespace. It provides syntax and examples for each function. The document concludes with some assignments asking the user to input strings and use the string functions.

This document provides information about files and the file system in PHP. It defines what a file is, explains common file types, and discusses magic constants and functions for working with files. It also covers opening, reading, writing, moving, and deleting files as well as functions for working with directories. Key functions discussed include fopen(), fread(), fwrite(), filesize(), unlink(), and file_put_contents().
This document provides an introduction to databases and MySQL. It discusses what databases are, why they are used, and some common database management systems. It then demonstrates how to connect to a MySQL database, issue basic queries, create and describe a sample table, and delete a table. The key aspects covered are connecting to MySQL, executing basic queries, creating a database and table, and verifying the table structure.
Aggregate functions summarize data from multiple rows into a single value. They operate on a single column and return a single value. Common aggregate functions include SUM, AVG, MIN, MAX, and COUNT. SUM returns the sum of numeric column values. AVG returns the average of numeric column values. MIN and MAX return the minimum and maximum values in a column. COUNT returns the number of rows.
This document discusses server-side form validation in PHP. It covers checking for empty fields, field lengths, value ranges, and formats using regular expressions. Specific PHP functions discussed include preg_match() for pattern matching, preg_replace() for search and replace, and ereg() as an alternative to preg_match() for POSIX regular expressions. Examples are provided to validate dates, names, numbers, lengths, and ranges to restrict user-submitted form data to required standards before processing.
This document discusses client-side form validation using JavaScript. It begins by introducing client-side validation and how it provides validation in the browser through JavaScript downloaded with the web page, making it generally faster than server-side validation. It then covers techniques for client-side validation including checking for empty fields, using regular expressions to validate formats, and JavaScript methods like test(), exec(), replace(), match(), and search() that can be used to validate form fields.
The document discusses JavaScript's Math, history, and location objects. It explains that the history object maintains a list of URLs visited by the user and allows navigating back and forward. The location object contains information about the current URL and can be used to assign or replace URLs. The Math object provides constants and functions for mathematical tasks without needing to be defined, such as PI and functions for trigonometry, rounding, and generating random numbers.
This document contains summaries of JavaScript concepts including arrays, strings, setInterval and clearInterval functions. It defines arrays as ordered collections of values that can be one or multi-dimensional. It also describes common string methods like charAt(), charCodeAt(), and slice(). Finally, it explains that setInterval calls a function repeatedly at specified intervals until clearInterval is called to stop it.
This document contains information about JavaScript dialog boxes, functions, events, and the Document Object Model (DOM). It describes the different types of dialog boxes in JavaScript - alert, confirm, and prompt - and how to use them. It also explains what functions are in JavaScript, how to define and call them, and how to pass parameters and return values. Additionally, it lists some common HTML events and provides an overview of the DOM hierarchy with the Window and Document objects at the top.
The document provides an introduction to JavaScript, covering what is needed to know, JavaScript's history and capabilities, how and where to place JavaScript code, and basic syntax features like variables, scope, and comments. It explains that JavaScript can be used to add interactivity and dynamic behavior to web pages, gives an overview of its syntax which resembles C/C++/Java, and notes it is an interpreted language run in the browser.
The Document Object Model (DOM) describes the structure of an HTML document and the relationship between its elements. The DOM represents the page as nodes organized in a tree structure. Nodes can be elements, attributes, and text. Elements are parent nodes that can have child nodes, and elements on the same level are siblings. The DOM provides access to elements via methods like getElementById, getElementsByTagName, and by accessing named form elements through the document.forms object.
This document discusses functions in PHP. It explains that functions allow reusing code by defining reusable blocks of code that can be executed multiple times by calling the function. It provides examples of defining functions, passing parameters to functions, returning values from functions, and variable scope within functions. It also discusses including files in PHP to break programs into multiple files.
Arrays allow the storage of multiple values under a single variable name. There are two types of arrays in PHP - indexed and associative. Indexed arrays use integers as keys, while associative arrays use strings. Values can be accessed and modified using the array name and key in square brackets. Arrays can be iterated through using a foreach loop to execute code on each value. Functions like count() and sizeof() return the number of elements in an array.
