Setting a function equal a variable?

Question

I have a PHP function and I want it to equal a variable. Here is the code:

Answer 1

You can't make a function equal a variable, but how about a variable that equals a function?

$ItsaFunction = function() {
    //Code goes here
};

You could also do

function ItsaFunction() {
    //Code goes here
}

$ItsaFunction = ItsaFunction();
