Store function inside an array

问题

Can I do something like this?

$arrayFn[1] = function fnName(){
    echo "test";
}
$arrayFn[1];

回答1:

Anonymous functions cannot have a name:

$arrayFn[1] = function (){
   echo "test";
};
$arrayFn[1](); // run it!

回答2:

$arrayFn[1] = function (){
echo "test";
}; 
$arrayFn[1]();
