Explore the JavaScript switch statement, using single-character input to classify vowels and consonants, with multiple cases, a default block, and direct case matching.

Learn to use JavaScript operators, including assignment, arithmetic, and unary forms; understand operator precedence and shorthand, such as +=, and pre/post increment and decrement with practical examples.

Explore how to use JavaScript logical operators (and, or, not) and the ternary operator to evaluate username and password checks, producing welcome or invalid user outcomes.

Explore JavaScript comparison operators, including equals, not equals, greater than, less than, and their inclusive forms, all returning booleans in expressions, demonstrated with 100 versus 10.

Learn how JavaScript functions enable modular, reusable code by defining functions, passing parameters, returning values, and invoking them through events like button clicks.

Explore JavaScript events and event-driven programming by wiring DOM events such as onload, mouseover, and mouseout to update image sources and other elements for responsive web interfaces.

Master JavaScript error handling with try, catch, and finally to manage runtime exceptions and ensure cleanup after external connections or data reads.

Learn how cookies enable client-side state management in JavaScript by creating session and persistent cookies, storing form values with document.cookie, and practical implementation via a simple name form.

Learn to build a client-side image slideshow with JavaScript using setInterval to cycle through four images, pause on hover, and start on page load, without any page postbacks.

Learn how to create a JavaScript object with properties like topic, trainer, and mode, access them with dot notation, and read values using a for-in loop and split method.

Learn to navigate between web pages using JavaScript page redirection with window.location, triggering redirects on events or after a timeout via setTimeout.

Explore the basic syntax of PHP, write a simple hello world script, and run it from the command line or as a web page using a local web server.

Explore the difference between client-side JavaScript and server-side PHP, illustrating how each computes and displays dates, with localhost versus remote clients and time zone effects.

Explore console input and output in PHP using standard input and output streams. Read integers with a scanner-like function and display results with printf, via command-line execution.

Explore PHP arithmetic operators by testing addition, subtraction, multiplication, division, integer division, and increment/decrement on sample variables, and verify outcomes in a running script.

Learn PHP comparison operators such as equal to, not equal to, greater than, less than, greater than or equal to, and less than or equal to, returning true or false.

Explore PHP assignment operators, including = and cumulative operators such as +=, -=, *=, /=, and %=, with practical examples showing how values update.

Explore the PHP conditional (ternary) operator, compare two expressions based on a condition, and see how ? : acts as a short form of an if statement.

Explore how PHP functions handle arguments with call by value and call by reference, set default parameters, accept variable numbers of arguments, and return values to callers.

Explore how the break statement terminates a loop in PHP by stopping execution as soon as a condition is met, such as a random number equaling five.

Explore how the continue statement influences a PHP while loop by skipping current iteration and starting the next, contrasting with break, using a random number example to show conditional printing.

Learn how PHP decision making works by using if, elseif, else and switch statements, with coalesce and rand to generate numbers and control flow through blocks and break statements.

Explore the PHP while loop by watching its execution from i values 0 to 9 and using a random number generator to loop until x equals 5.

This lecture demonstrates the PHP for loop syntax with initialization, condition, and increment, including three examples: printing numbers from 1 to 10, random termination, and traversing a five-element array.

Demonstrates using the MySchool API with PHP to connect to a MySQL database, create databases and tables, insert records via forms, and read data with select queries.

Explore the mysqli API in PHP through procedural and object-oriented approaches to connect to a database, create databases and tables, insert data, and display records from the employee table.

Explore inheritance in PHP by extending a parent student class with a child engineering student class, reusing protected members, passing constructor arguments, and overriding get details to add branch.

Create and manipulate PHP objects with a books class, using a constructor, setters and getters, and a get details method to display title and price, then sum prices of objects.

Explore PHP 7 anonymous classes by creating an unnamed class with a constructor that sets X and adds and subtracts. With X set to 10, add 20 yields 30.
