Learn embedding PHP in a page, use echo and concatenation for hello world, perform calculations, manage spaces, and document with comments and file naming.

Understand the PHP request and response cycle, from browser input to Apache processing on the server, with optional database interactions and rendering results in the browser.

Learn PHP data types, from strings and integers to floats, booleans, arrays, objects, null, and resources, with examples like storing names, ages, scores, and pass/fail status.

Learn how PHP variables store data as symbolic values that can change, using a dollar sign and names with letters, numbers, underscores, or dashes, and remember they are case sensitive.

Master strings in PHP by using double quotes and single quotes, including variables inside double quotes, and escaping characters with a backslash to control output.

Explore essential math operations in PHP, including computing min and max, absolute value, square root, rounding, and generating random numbers to enhance dynamic web applications.

PHP constants are defined with define, and remain fixed after definition. The lesson demonstrates default case sensitivity, how to enable case-insensitive constants, and using examples like username and birth year.

Explore PHP operators, including assignment and arithmetic, comparison (==, ===, !=, !==, >, <, >=, <=), increment/decrement, logical operators (and, or, not), and the ternary operator.

Learn PHP string functions: concatenate strings with the dot operator, trim and measure lengths, convert cases (strtolower, strtoupper, ucwords, ucfirst), search with strpos, replace with str_replace, repeat, and extract substrings.

Explore PHP data types by illustrating strings, integers, floats, booleans, and arrays, using variables and zero-based indexing in nested arrays to produce organized browser output with proper formatting.

Learn to work with arrays in PHP by indexing from zero, adding and removing items, counting elements, and retrieving the first and last items in browser output.

Learn essential php array functions: push to add items, pop to remove the last item, shift to remove the first, and merge to combine arrays, then sort and reverse results.

Store keys and values in a PHP array and echo Alex and Jessica's phone numbers. Add Michael's number to the array and retrieve only the keys or only the values.

Master conditions in PHP by using if statements to compare user input with a number, apply comparison operators, and validate numeric data versus strings to display precise messages.

Explore loops in PHP, including while and for variants, and the foreach loop, with break and continue control flow, increment operations, and practical browser demonstrations.

Discover how to define and call PHP functions, pass parameters, and echo results; use functions for numbers, addition, and loops to print sequences from start to end.

Learn to use PHP date function for custom formats, and master include and require to modularize pages, including handling database connections and navigation bars.

Learn to handle forms in PHP by using the post method, action, and retrieving data with $_POST; build login logic, and secure passwords with encryption.

Connect your PHP application to a MySQL database using localhost and phpMyAdmin, configure a user and database, and test the connection to ensure data can be stored and retrieved.

Explore how a database mirrors a file system, with folders as databases and tables as categories like employees and jobs, detailing rows, fields, and simple user–job relationships.

Set up a demo database and an employees table with id, name, email, and phone, then insert and browse sample records like Jane Doe and John Doe.

Learn how to create and insert user data into a MySQL database using a PHP form, with an admin area protecting data visibility and a front-end submission flow.

Learn how to read and display MySQL data on the front end with a PHP script, fetching employee details and rendering them in HTML for the user.

Learn to fetch a single user's details from a list in PHP and MySQL by passing the user id via GET, querying for that id, and showing a detailed view.

Learn to update a user's record via a PHP form, fetch and populate details from the database, and implement front-end update and delete actions with MySQL queries.

Learn how to delete a user from a MySQL database using a simple delete query, including handling the id, data loss cautions, and the fact that IDs remain unique.

Create and secure a login and registration page using PHP and MySQL, with username, password, and email fields, password encryption, database insertion, and login redirection.

Create a login page collecting the username and password, validating them against the users table in the database, and showing a success or incorrect credentials alert.

Use PHP sessions to protect pages by starting a session on the login page, validating credentials, and storing the username in $_SESSION to grant dashboard access.

Enhance an ems app dashboard by adding a bootstrap navbar, refining the header into a welcome container, and securing the page with a session-based access check.

Learn to build a PHP and MySQL dashboard with a sidebar, an employee list, and a form to add new employees, including details, edit, and delete actions.

Add and display the employee list in the dashboard by fetching all employees, building the table, and enabling details, edit, and delete actions.

Create the add new employee form on a dedicated page with name, email, and phone fields. Enforce required fields with placeholders and insert data into the database, refreshing the employee list.

Create a single employee details page that reads the employee id via get, displays data in a structured table, and enables editing and deleting actions.

Create a single employee edit page, populate the form with current details, and implement the update workflow to save changes through the edit and update actions.

Create a delete single employee page, connect it to the backend, and use the delete button to remove employees from the dashboard, completing the basic employee management flow.

Learn to host your PHP and MySQL application on a web host by creating a site, uploading and extracting files with a file manager, and configuring MySQL database at localhost.

Extend your PHP and MySQL skills by exploring frameworks and content management system options; WordPress offers quick setup with themes and plugins, while Laravel remains a strong framework.
