I hope you're having a great day. I have recently started learning PHP and I came across a doubt regarding arithmetic operations on different data types in PHP. I am wondering if it is possible to perform arithmetic operations with different data types in PHP.
As I progress in my PHP journey, I am finding myself working with various data types such as integers, floats, strings, and even arrays. I know that PHP is a dynamically typed language that automatically converts data types when needed. However, I'm unsure if this applies to arithmetic operations as well.
To give you a specific example, let's say I have a variable $number1 containing an integer value of 10, and another variable $number2 containing a string value of "5". If I try to add these two variables together like $result = $number1 + $number2, will PHP implicitly convert the string to an integer and provide the correct result of 15?
I have tried searching online for information on this topic but haven't been able to find a clear answer. It would be great if someone with experience in PHP could shed some light on this. I want to ensure that my arithmetic operations are accurate regardless of the data types involved.
Thank you very much in advance for your help and insights. I appreciate your time and expertise.
