Question

In any programming language (like php, java, javascript etc) is it possible to dynamically create a changing number of variables in a loop, within a given name space?

for example, if I want to create N variables that have random numbers between 1 and 5, which are to be called random1, random2 .. randomN, is it possible to do something like:

loop ( N ){<br>
  create variable randomN = random(1,5);<br>
}

In PHP you could use variable variables:

$N = 5;
for ($i = 0; $i != $N; ++$i) {
    ${"random$i"} = rand(1, 5);
}

In JavaScript, same thing:

var N = 5;
for (var i = 0; i != N; ++i) {
    window['random' + i] = Math.round(Math.random() * 5);
}

Though, I would recommend using a “container” to hold those variables, so that they’re not created globally.
