PHP - Master PHP for Back End Web Development with MySQL

Explore the basic PHP building blocks—syntax, variables, and data types—learn to write PHP code with proper tags, semicolons, and comments, and display values using echo.

Learn how PHP handles operators and expressions, including arithmetic, comparison, logical, and assignment operators, with examples that show how expressions produce values and drive output.

Master PHP conditional statements, including if, else, and switch, through practical examples like voting eligibility, temperature checks, and day name routing.

Explore how PHP loops—for, while, do while, and foreach—repeat tasks automatically, count iterations, and iterate arrays to make programs more efficient.

Master PHP arrays and functions by building indexed and associative arrays, looping with for and foreach, printing results with echo, and creating reusable functions to process and sum data.

Learn to build HTML forms and connect them to PHP to collect and process user input using GET and POST methods, then display name and age with simple coding examples.

Learn how get and post methods send data from HTML forms to a PHP script, with get exposing data in the URL and post hiding it in the HTTP body.

Learn how to upload files with PHP, using a multipart form and move_uploaded_file to save to a destination folder, with validation and display of file name, type, and size.

Build a PHP and MySQL based user registration and login system, including registration form handling, password hashing, and login validation to securely store and verify user credentials.

Learn how PHP hashes passwords with password_hash and verifies them with password_verify to secure user data and authenticate logins using salted hashes.

Master PHP sessions by using session_start to store user data in $_SESSION on the server, access it across pages, and destroy the session at logout.

Protect pages with login authentication in php by starting a session, validating posted username and password against hard-coded credentials, and redirecting to coding.php on success or showing an error.

Learn to encode PHP arrays to JSON and decode JSON back to PHP using json_encode and json_decode, returning associative arrays when you pass true, enabling web data exchange.

Learn how to use PHP with APIs to fetch public API data and send post requests with cURL, decoding JSON responses.

Learn how to create, write, and upload files in PHP using fopen, fwrite, and fclose, and build a simple file upload form that moves files to an uploads directory.

Explore php date and time functions to display current dates and timestamps, set time zones, format dates, and use strtotime to compute future and past dates for logging and scheduling.

Discover how to create and manage a MySQL database using phpMyAdmin, including creating databases, adding tables, inserting data, and editing or deleting records.

Explore how PHP connects to MySQL databases using a local server, localhost and root credentials, to establish a successful connection for dynamic web apps like login systems.

Learn to execute sql queries in php using mysql, create a student table with id, name, email, and age, and insert a new record with a successful output.

Fetch and display data from a MySQL database using PHP, covering database setup, table creation, data insertion, and a select query to show results in a browser.

Explore detecting, debugging, and fixing php errors—from syntax errors to notices—using error reporting and try-catch to build secure, user-friendly back-end applications.

Learn to insert data into a mysqli database using php by setting up a database and employees table in phpmyadmin, then connecting and executing an insert query.

Fetch and display data dynamically from a MySQL database with PHP by retrieving all records from the student table and showing id, name, email, and course on a web page.

Learn to update existing records in a mysql database with php and sql, using an employee table and an update query to change the department.

Delete records securely from a MySQL database using PHP by performing a delete operation with a where clause and prepared statements to prevent vulnerabilities.
