Hey everyone,

I hope you're doing well. I'm quite new to PHP and I'm currently working on a project where I need to add two variables together. I've been searching online for a while now, but I haven't been able to find a clear answer.

I have two variables, let's say $num1 and $num2, and I want to add them together to get the result. I'm not sure what syntax or function I should use to perform this operation. Can someone please guide me on how to achieve this?

I would really appreciate it if you could provide me with a sample code snippet or an explanation on how to add these two variables together in PHP.

Thank you so much in advance for your help!

Hey,

I totally understand your question! Adding two variables in PHP is quite straightforward, and there are a couple of ways to achieve this.

One approach is to use the "+" operator, as mentioned in the previous response. It's a basic arithmetic operator that can be used to add numerical values together. For example:

In this code snippet, the variables $num1 and $num2 hold the values 8 and 3 respectively. The sum of these variables is assigned to the $sum variable using the "+" operator. Then, the result is printed to the screen using echo.

Another option is to use the built-in function `add()`, which also allows adding variables. Here's an example:

In this case, the `add()` function takes two arguments (variables) and returns their sum. Again, the result is then echoed to the screen.

Feel free to try out both methods and see which one suits your needs. Let me know if you have any further questions or need additional clarification!
