learn arithmetic and assignment operators in PHP, including plus, minus, multiply, divide, and modulus, with practical examples using x and y to show outputs.

Explore how assignment operators work in PHP, including =, +=, -=, *=, /= and <=, with practical examples showing how variables receive and update values and how echo outputs results.

Master PHP comparison operators, including assignment vs equality, and identical (===) and not identical (!==) checks, with <, <=, >, and >= across numbers and strings.

Explore how the increment and decrement unary operators modify a variable, including pre increment, post increment, pre decrement, and post decrement, with simple value examples.

Explore PHP logical operators, including and, or, xor, and not, with booleans and practical examples that show how combined expressions yield true or false results.

Learn php string operators, including the concatenation (dot) operator to join strings and the assignment operator to assign the result, with practical variable examples.

Learn how to use the PHP get method to retrieve form data via URL parameters, collecting name and email with $_GET and noting its limitations.

Learn how the post method in PHP transmits data and binary content without exposing it in the URL, unlike get, and why it is preferable for sending sensitive information.

Create a PHP contact form using the post method with fields for full name, email, subject, and message, including a textarea and a submit button, and process submissions.

Explain global and local variables, show that local variables are inside a function, global variables outside, and how the global keyword makes a variable accessible inside and outside functions.

Explore if statements in this PHP/MySQL course, showing how a conditional statement evaluates true or false and executes the appropriate code or displays alternate output.

Explore how if and else statements evaluate conditions, execute corresponding results for gender-based and age-based scenarios, and chain else if branches to handle multiple outcomes.

Discover how if-else if statements control program flow by executing code when conditions are met and skipping to alternatives when not, illustrated with age comparisons and echo outputs.

Learn how a switch statement directs program flow by evaluating conditions and executing the matching case with break, including multiple cases and a default.

Explore the for loop, foreach loop, and nested for loop in PHP, understanding how initialization, condition, and increment expressions automate code execution a fixed number of times.

Learn how the for each loop iterates over arrays and their elements, simplifying execution and printing values while handling memory considerations behind the scenes. Explore keyword usage and basic syntax.

Explore how a nested for loop works, with an outer loop and an inner loop, and see how coordinated iterations print results.

Demonstrate how the while loop executes a code block repeatedly while a condition is true, including counting from one to four and reading database records in Java or C++.

Explore the do-while loop, which executes at least once before checking the condition. See a simple example counting from 1 to 5 using an increment operator.

Explore PHP arrays, including indexed and multidimensional arrays, with practical country-list examples, learn how numeric keys start at zero, retrieve values by index, and use arrays efficiently.

Discover how PHP associative arrays use string keys to map values, then create and iterate them with foreach, printing keys and values as country examples.

Explore how PHP multidimensional arrays store nested data, like matrices of people with addresses and emails, and access elements by indices to retrieve specific details.

Explore how PHP provides sorting functions and options, including numeric, case-insensitive, and natural order, to sort arrays in ascending order with practical examples.

Learn to create a PHP powered HTML table using a for loop, echoing tr and td elements to build a 2-column by 3-row multiplication table with border and cell padding.

Define and create reusable PHP functions by declaring a function, naming it, writing its code, and calling it to execute tasks in a student–teacher–admin workflow.

learn how to define a function with parameters, pass values to the function, and compute the result by summing the inputs, as shown in a practical example.

Explore how PHP functions pass arguments by value and by reference, learn to pass by reference via the address, and see how references affect variables inside and outside functions.

Explore how a function in PHP returns a value to the calling script using the return statement, with examples that show passing parameters and capturing the result in a variable.

Define and use functions with optional parameters and default values in PHP to simplify calls, showing how defaults apply when arguments are omitted and how to override them.

Explore dynamic function calls in PHP by storing a function name in a variable and invoking it at runtime based on inputs. The lecture demonstrates calling ABC dynamically.

Explore anonymous functions, also known as closures, which have no name and can serve as callback values; the lecture shows assigning one to a variable and invoking it.

Explore PHP variable scope, clarifying global and local visibility, how variables inside a function stay undefined outside, and how undefined variable errors occur, with global variables accessible everywhere.

Explore how recursive functions call themselves until a base condition is met, illustrated with the Tower of Hanoi and factorial examples in PHP.

Explore break statements in PHP to control program flow, exit loops or switches, and resume execution outside the loop with practical for-loop examples.

Explore continuous statements and their effect on the flow of programs under certain conditions, showing how to continue execution and skip unwanted steps.

Explore PHP math operations using built-in functions such as abs, ceil, and floor to process numbers, show rounding behavior, and demonstrate string concatenation of results.

Learn how to create XHTML forms with HTML5, including contact and registration forms, using labels, inputs, text areas, and the post method to collect data.

Learn form handling in php by building html forms, processing user input with the post method, validating fields, displaying errors, and optionally sending emails with headers.

Learn to implement required form fields in PHP, validate user input for name and email with the post method, display error messages for empty fields, and handle form actions.

Learn how exception handling manages runtime errors using try, throw, and catch blocks, with real-world examples like division by zero.

Open a file in PHP using fopen, including reading and writing modes. Demonstrate opening and closing files, and basic error handling for file operations.

Learn to write to and overwrite an existing PHP file, using write mode to replace text and append mode to add new lines, then close the file.
