What correction was suggested by other forum users to fix the issue in the PHP script?

The issue in the PHP script was that the variable `$result` was being accessed outside the scope of the foreach loop, causing it to only store the last value of the loop. To fix this, other forum users suggested moving the declaration of `$result` inside the loop so that it can store all values from each iteration.

$result = array();
foreach ($array as $item) {
    // perform some operations on $item
    $result[] = $item;
}
