Introduction to PHP: Building the Basics

Learning Objective

Understand the basics of PHP programming language and its use in web development.

What do you already know about programming languages?

Slide 1: What is PHP?

PHP is a server-side scripting language designed for web development but also used as a general-purpose programming language.

Slide 2: PHP Syntax

PHP code is embedded within HTML code, and it is executed on the server before the resulting HTML is sent to the client's web browser.

Slide 3: Variables and Data Types

PHP supports various data types including strings, integers, floats, booleans, arrays, and objects.

Slide 4: Control Structures

PHP provides a variety of control structures such as if statements, loops, and switch statements for decision-making and iteration.

Slide 5: Functions and Arrays

Functions allow you to group code into reusable blocks, and arrays are used to store multiple values in a single variable.

Slide 6: Form Handling

PHP is commonly used for processing data from web forms, allowing for dynamic interaction with users.

Slide 7: File Handling

PHP can read, write, create, and delete files on the server, making it a powerful tool for file management.

Slide 8: Object-Oriented Programming

PHP supports object-oriented programming principles such as classes, objects, inheritance, and polymorphism.

Slide 9: Error Handling and Security

PHP provides features for error handling and various security mechanisms to protect web applications from vulnerabilities.

Slide 10: Conclusion

Summarize the key points covered and encourage further exploration of PHP through practice and projects.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
