In what situations is it unnecessary to use a helper variable like "$i" in PHP scripts, and what are the alternatives?

In PHP scripts, it is unnecessary to use a helper variable like "$i" when iterating over arrays using a foreach loop. This is because the foreach loop automatically assigns the current element to a temporary variable without the need for an additional helper variable. Instead of using "$i", you can directly access the current element within the loop. 

// Using foreach loop without a helper variable
$numbers = [1, 2, 3, 4, 5];

foreach ($numbers as $number) {
    echo $number . "<br>";
}
