What is the correct syntax for defining a function in PHP?

When defining a function in PHP, the correct syntax includes the keyword "function" followed by the function name, parentheses for any parameters, and curly braces for the function body. Parameters are optional and can be specified within the parentheses. To define a function in PHP, you need to follow this syntax to ensure that the function is correctly declared and can be called later in your code.
