Learn PHP basics with hands-on practice in hello world in PHP, variables in PHP, functions in PHP, arrays in PHP, PHP inheritance, PHP exceptions, and more.

This interactive course introduces you to the fundamentals of PHP programming, one of the most widely used languages in web development. Starting with a simple hello world in PHP, you’ll explore the basics, including PHP output, variables in PHP, and PHP data types. You’ll also learn about PHP constants, arithmetic operators, comparison operators, logical operators, and assignment operators.

The course progresses into conditional statements in PHP, PHP switch, and various loops such as PHP for loop, PHP while loop, and more. You will then dive deeper into functions in PHP, understand PHP variable scope, and learn PHP pass by reference or value. Additionally, you’ll gain a working knowledge of strings in PHP, PHP string operations, and handling arrays in PHP, including PHP multidimensional arrays.

# What is an Exception?
An **exception** is an unexpected program result that can be handled by the program itself. **Exception Handling** in PHP is almost similar to exception handling in all programming languages. 

# What Happens When an Exception is Triggered?
When an exception is triggered, the current code state is saved. The code execution will switch to a predefined (custom) exception handler function
Depending on the situation, the handler may then resume the execution from the saved code state, terminate the script execution or continue the script from a different location in the code.

# Exception Handling in PHP
PHP provides the following specialized keywords for this purpose:

- try
- throw
- catch
- finally

In the next lesson, we will learn about these keywords in detail.

This lesson discusses what exceptions are and how PHP allows you to handle them.
