Mastering PHP, MySQL and JavaScript for web developers

Explore JavaScript data types, including strings, numbers, booleans, arrays, and objects, and learn how to declare and access variables with let, using double or single quotes.

Explore how numbers function as a core data type, including integers and decimals, and how unquoted numbers differ from strings in arithmetic operations.

Learn string formatting in JavaScript by concatenating variables such as first name, last name, and name, then display dynamic output in the browser using backslashes to create multi-line strings.

Explore arithmetic operators in JavaScript, including plus, minus, multiplication, division, and increment/decrement. Practice assignment, comparison, and logical operators with pre- and post-increment behavior.

Master assignment operators and related arithmetic operators by using the equals sign to assign values to variables and updating them with plus equal, minus equal, multiply equal, and divide equal.

Master the use of logical operators in JavaScript, including and, or, and not, with practical examples that compare values and evaluate combined conditions to control program flow.

Learn how to implement if, elseif, and else decision logic with multiple conditions, test values like good morning to good evening, and prepare for switch cases in coding.

Master the while loop in web development basics, exploring control flow, conditions, and iterating to print numbers. Build a simple multiplication table using incrementing loops.

Learn how the do-while loop executes by entering the code block before testing the condition, compare it with while, and see practical examples in JavaScript.

Learn how to use for loop statements in PHP and JavaScript to initialize, test, and increment iterations, and to iterate over strings and arrays such as fruits.

Solve a JavaScript exercise to print a multiplication table for the number two, up to ten levels, formatted in a diamond layout.

Define a JavaScript function with multiple parameters, call it with the call method to pass first and last names plus city and country, and produce formatted full names.

Explore how to create a function with parameters, accumulate a sum with a for loop, and handle dynamic arguments in JavaScript, highlighting value versus reference semantics.

Master the try-catch-finally pattern in JavaScript to handle errors and ensure final code runs, with input validation, DOM updates, and user feedback for web development.

Implement on submit form validation with a JavaScript function that checks name and email fields. Hook this validation to onsubmit, use post, and rely on return false until inputs pass.

Learn to validate numeric input in web forms with HTML and JavaScript, handle non numeric values with on submit validation, and show inline error messages to ensure clean data.

Explore PHP as an open-source, server-side language for dynamic web pages and basic output. Implement PHP 7 and 8.x upgrades with Apache and database operations for real-world dynamic content.

Create a PHP project on XAMPP by configuring htdocs, creating a project folder, and starting Apache and MySQL, then access localhost to verify with a welcome page.

Create a PHP project on XAMPP by writing a hello world welcome program in PHP, using Sublime Text Editor, save as welcome.php, and run on localhost to see the echo.
