Hey everyone,

I'm new to PHP and currently learning about arithmetic operations in the language. I understand that there are various operators like addition, subtraction, multiplication, and division, but I'm not sure which ones are specifically used in PHP. Could someone please enlighten me on the arithmetic operators in PHP and how they work? I would greatly appreciate any explanations or examples you could provide. Thanks in advance!

Hey there!

I'm glad you're exploring PHP and its arithmetic operators. I can definitely share my personal experience with them.

In PHP, arithmetic operators are fundamental for performing mathematical calculations. The common ones are:

- Addition: `+`

This operator allows you to add two numbers together. For example, `3 + 5` would give you the result of 8.

- Subtraction: `-`

The subtraction operator is used to subtract one number from another. For instance, if you have `10 - 4`, the result would be 6.

- Multiplication: `*`

With the multiplication operator, you can multiply two numbers. For example, `2 * 6` would give you the result of 12.

- Division: `/`

The division operator divides one number by another. So, if you have `15 / 3`, the result would be 5.

In addition to these basic arithmetic operators, PHP provides a few more:

- Modulus: `%`

The modulus operator returns the remainder of the division between two numbers. For instance, if you do `13 % 5`, the result would be 3, as 13 divided by 5 leaves a remainder of 3.

- Exponentiation: `**`

The exponentiation operator raises a number to a power. For example, `2 ** 4` would give you 16, as 2 raised to the power of 4 is 16.

It's worth mentioning that PHP also offers shorthand assignment operators, like `+=`, `-=` and more. These allow you to perform an arithmetic operation and assign the new value to a variable in one go.

I hope this provides some clarity on the arithmetic operators in PHP. If you have any further questions or need further assistance, feel free to ask. Happy coding!
