How to use a variable used in 'for' loop PHP?

Question

when using a for loop in PHP are the variables used inside available outside of the loop and if not is there a way of doing so?

foreach ($rows as $row){
    $name = $row ['surname'];
    $validpassword = ($validpassword + 1);
}

Will I be able to use $validpassword outside of the loop?

Answer 1

Yes, the variable scope is not limited to the loop.
