Php writing a function with unknown parameters?

Question

How would I go about writing a function in php with an unknown number of parameters, for example

function echoData (parameter1, parameter2,) {
    //do somet         


        

Answer 1

func_get_args()

function echoData(){
    $args = func_get_args();
}

Be aware that while you can do it, you shouldn't define any arguments in the function declaration if you are going to use func_get_args() - simply because it gets very confusing if/when any of the defined arguments are omitted
