PHP - 2D arrays - Quoting through array keys and extracting their values?

I have an array that is output as follows:

1 => 
array
  'quantity' => string '2' (length=1)
  'total' => string '187.90' (length=6)

2 => 
array
  'quantity' => string '2' (length=1)
  'total' => string '2,349.90' (length=8)

I would like to skip all the keys of the array and get a set of 3 values ​​related to them, something like this (which doesn't work):

foreach( $orderItems as $obj=>$quantity=>$total)
{
    echo $obj;
    echo $quantity;
    echo $total;
}

Someone will be able to give some advice on how I accomplished this, or even the best way for me in this solution. Any information related to this, including links to tutorials that may cover this, would be greatly appreciated. Thank!!

foreach( $orderItems as $key => $obj)
{
    echo $key;
    echo $obj['quantity'];
    echo $obj['total'];
}

Using the above.

You need to read the documents a forEach()little more, since your syntax and understanding of this is somewhat incorrect.

$arr = array(
    array('foo' => 'bar', 'foo2', 'bar2'),
    array('foo' => 'bar', 'foo2', 'bar2'),
);
foreach($arr as $sub_array) {
    echo $sub_array['foo'];
    echo $sub_array['bar'];
}

forEach() - $sub_array ( , ). , , .
