PHP Programming for Web Development Fundamentals

Learn the difference between client and server, how a browser sends requests and receives responses, and how PHP on the server processes data and SQL queries to generate dynamic content.

Discover how modern websites collect and securely process user data using html forms and php. Store data in databases with post method, input validation, and encryption to protect sensitive information.

Discover PHP, a server-side language for dynamic web pages that embeds in HTML, covers environment setup, open-source status, databases MySQL, Oracle, PostgreSQL, and frameworks like Laravel.

Set up a PHP development environment with an all-in-one package including PHP, MySQL, and Apache, run code on localhost, and create hello world using echo.

Learn how PHP variables are declared and initialized with a dollar sign, manage data types, and apply naming rules, then update values with echo statements and semicolons.

Define PHP constants with define, fixing values that never change and are globally accessible. Follow naming rules (no dollar sign; starts with letter or underscore) with examples age and name.

Learn how to retrieve user input in PHP using HTML forms, employing $_POST and $_GET to capture fields like name and email and display them on the same page.

Learn how to output text and variables in PHP using echo and print, compare their syntax, return values, and limits for multiple statements in a browser-based example.

Explore PHP comments, using single-line // and # and multi-line /* */ syntax, to document code, prevent execution, and guide future developers.

Discover the core php data types, including integer, float, string, boolean, array, object, and null, with practical code examples and an object oriented approach.

Learn PHP arithmetic operators in a one-day course, focusing on addition, subtraction, multiplication, division, modulus, and exponentiation during the afternoon session.

Explore comparison operators in PHP with practical code examples. Learn how equal, not equal, identical, not identical, and relational operators like less than and greater than produce boolean results.

Master PHP logical operators by exploring and, or, xor, and not through practical examples, including voting eligibility logic and real code demonstrations in Visual Studio Code.

Explore how the assignment operator sets and updates variable values in php, including addition and subtraction assignment operators, with practical code examples.

Master the PHP ternary conditional operator by evaluating a condition like whether a equals four, returning yes or no and storing the result in a variable, with practical code examples.

Learn how the PHP string concatenation operator (dot) joins multiple strings with a space using practical examples, and echo the combined results.

Explore PHP membership operators, including in_array and substring checks, to determine if a value exists in an array or string, with true or false outcomes and practical examples.

Explore decision making in PHP by using if, if else, and switch statements to control code flow based on conditions; learn syntax, conditions, and examples like checking numbers and grades.

Learn php's if else if else syntax to test multiple conditions in sequence and run the first true block, else handle the all-false case with a marks example.

Learn how to use PHP switch statements as an alternative to if-else, selecting one code block based on a variable’s value with case, break, and a default.

Use while loops in PHP to repeat statements until a condition becomes false, including initialization, increment, and decrement. See examples printing 0 to 10 and 10 to 1.

Discover the do while loop in PHP, where the condition is checked at the end, ensuring at least one execution, with examples from 1 to 10 and 10 to 1.

Explore PHP for loops, including syntax, initialization, condition, and increment/decrement, and generate sequences from 1 to 10 or 10 to 1, with even and odd filtering using modulus.

Learn to iterate arrays with foreach in PHP, displaying each element and handling keys, values, and line breaks while exploring examples with numbers, colors, and students.

Learn how to create and access PHP arrays, storing multiple values and indexing items from zero to n minus one. Explore array types—indexed, associative, and multidimensional—and for each loops.

Master including PHP files with include and require to modularize headers, navs, main content, and footers. Learn the key difference: include continues on failure, while require halts execution.

Master PHP functions by defining reusable blocks with parameters, returning values, and calling them across pages, illustrated through user registration and basic arithmetic examples.

This lecture explains PHP function overloading, shows PHP lacks native support, and demonstrates a single function using a switch on an operation parameter to perform add, subtract, multiply, or divide.

explains get and post methods in php, showing get data in the url and post data in the request body from html forms, and when to use each for submissions.
