Master nested if statements in PHP by building a practical two-subject grade decision system. Apply conditional logic to determine results based on math and English scores.

Explore how to use the switch statement in PHP to handle multiple conditions, map fruit names to types with cases and breaks, and output the result.

Explore the PHP while loop as a fundamental construct that repeats code under a condition, with examples printing 1–5 and the first ten even numbers.

Learn how the do while loop in PHP executes a code block at least once and repeats while a condition holds. See examples printing 1 to 10 and calculating sum.

Learn how to use PHP for loops to iterate over numbers and arrays, printing multiples and fruit elements with practical examples, enabling dynamic website scripting with MySQL.

Explore how to encapsulate code with PHP functions, using built-in and user-defined functions; define functions with parameters and perform operations like multiplying two numbers and echoing the result.

Explore PHP arrays, including indexed and associative arrays, and learn to create a fruit index array, access elements by index, and display them.

Master indexed arrays in PHP by building a numeric array of tech gadgets. Add a new item, remove the third element, and display the updated list with a for loop.

Learn to create associative arrays in PHP, mapping custom keys like name, age, occupations, and location, then iterate with foreach and display results with echo for dynamic websites.

Explore multidimensional arrays in PHP, create and access two- and three-dimensional arrays like a matrix and a cube, and demonstrate indexing to retrieve elements.

Learn how php super globals like $_GET, $_POST, and $_SESSION enable access to global variables from any script, with an example of retrieving a name from the url.

Explore how PHP uses the $GLOBALS super global to access and modify global variables through functions, display changes, and build dynamic scripts.

Explore the PHP server superglobal to reveal server environment details and the current request, showing server name, document root, PHP version, and request method through practical code examples.

Learn to use the PHP super global $_REQUEST to handle and validate form data from get, post, and cookies, enabling dynamic data processing, submission checks, and clear output messages.

Learn how the post method, a super global for handling data, securely collects user input from an HTML form and processes the first name in PHP with checks and display.

Learn to use the $_GET superglobal and the get method to retrieve URL parameters from a simple HTML form and display them in PHP.

Learn how regular expressions in PHP define patterns and manipulate text for validating input and searching patterns, with practical pattern matching examples.

Discover how HTML and PHP collaborate to create dynamic forms with username and password fields, posting data to a server-side script for processing and validation.
