PHP Day 3: Numbers and Operators
Today I got familiar with the way PHP uses numbers and operators — just a basic introduction, only three minutes long.
Links for PHP Day 3: Numbers and Operators
Integers and Floats in PHP:
- PHP: Integers - The PHP manual’s page on integers.
- PHP: Floating Point Numbers - The PHP manual’s page on floats.
- Floating Point - Wikipedia explains what floating-point numbers are and how they work. (Not light reading!)
Operators in PHP:
- PHP Operators - A simple reference chart with examples.
- PHP: Operators - The PHP manual’s chapter on operators, with tons of information. Warning: reading too much of this may give you a headache!
- Order of Operations - If you need to refresh your memory, take a look at this page from Wikipedia.
I’m sure I’ll move on to some more advanced math in the future, but not until I need it.
