Functions

Function are defined using the following syntax:

rcaron
func Name($param, $optParam = 1) {
    // ...
    return 1
}

rcaron
func Name($param, $optParam = 1) {
    // ...
    return 1
}

The func keyword is followed by the name of the function, a list of parameters, and a block of code. The parameter param above is required, while optParam is optional and has a default value of 1. The return keyword is used to return a value from the function.

A function can be called using both the call-like and keyword plain call call types.
