Why is PHP so popular?
Developers love PHP for its simplicity. You can learn it quickly. Its way of writing code is similar to other popular languages, such as C and Java, which makes it familiar to many developers.
Another big reason for PHP's popularity is that it fuels teamwork. It's an "open-source" language, which means that developers all over the world can contribute to making it better. This collaboration has led to many helpful tools, guides, and pieces of code that speed up building websites.
