The operator precedence determines the order in which expressions will be evaluated. This is important. Think about it. Just like in math when you are solving for x in an expression such as x = 8 + 2 * 5, the order in which you solve the expressions changes the result. If you do the add first and then the multiplication, you get a different result than if you switched the order. In computation, it works the same way.
Associativity is a key part of precedence. PHP offers you left, right, and non-associative operators. Let’s learn about what this means and how it affects your expressions.
