php adding columns to a table

Question

I've got the function:

<?php
function calculatepoints($position) {
    $points = array (25, 18, 15, 12, 10, 8, 6, 4, 2, 1);
    if ( $position > count($points) ) { return 0; }
    else { return $points[$position-1]; }
}
?>

and would like to add a points column to my table. I've tried using:

<td><?php echo $points; ?></td>

but kept getting the error: "Undefined variable: points in ..."

Could someone please let me know what it is that I'm doing wrong?

Answer 1

It is because $points is in function's scope, yet you're trying to access it on global scope.

Do: <?php echo calculatePoints($position) ?>

Answer 2

Try:

<?php echo calculatepoints($position); ?>

You should read up on PHP variable scope .
