PHP variable variables

Question

I want to store courseworks marks of n courseworks into n variables, such as cw1 and cw2 etc. Using variable variables how can I come with cw1, cw2 etc.

How can I d

Answer 1

Variable variables work in this way

$var = "foo";
$$var = "bar";

echo $foo; // bar

But i do not recommend doing this, since what if the value of $var changes, then you can no longer print out the 3rd line in this code.

If you could elaborate more on what you want to do i think we could help you more.
