not able to print array variable

[hearn]

I'm using the following function:

function do_math($a, $b, $delta_x) {
    $sum = 0;
    $n_counter = 0;

do {
    $sum+=(do_function($a)*$delta_x);
    $a+=$delta_x;    
    $n_counter++;
    $sum_store[$n_counter] = $sum;
} while($a<$b);

return($sum);
}

My problem is that I'm not able to reference the variable sum_store from outside the function, it won't print. Does the variable or function need to be globalized somehow for this to work?

thanks in advance,
Cheers!

if you want to reference a variable outside the function's scope, use:

global $sum_store;

before you reference it.
