Sigh...

There is no thing like "bracketed arrays" or "standard arrays". This is
called one-dimensional and multi-dimensional. And of course foreach()
works fine with every kind of array.

<?php
$myarray = array(
  array( 'Apple', 1 ),
  array( 'Pie', 2 )
);

foreach($myarray as $item)
{
  echo $item[0] . ' - ' . $item[1] . '<br />';
}
?>

You just don't understand it - as usual.

As usual. while() needs more code, is slower and is prone to errors.

Really - software development is not your thing. It seems you are
mentally not capable of understanding the principles.
