Learn the fundamentals of PHP from structural programming to object-oriented techniques.

Web Development with PHP

This highly interactive module introduces us to fundamental programming concepts in PHP—one of the most popular languages in the world. It begins with a simple “Hello, World!” program and proceeds to cover common concepts such as conditional statements, loop statements, and logic in PHP. It then reflects upon the idea of functions and arrays, as well as the power they give to the programmer to write better code.

Finally, it dives deeper into advanced concepts such as classes, inheritance, and exception handling in PHP. By the time we're done, we’ll have a good grip on the basics of PHP and will be ready to study advanced concepts.

Learn PHP from Scratch

# 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 keywords 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 exception handling in PHP works.
