using foreach to loop through an array in the php Array's and Datastructures Course

Hello, Ive just been stumped on something that seems relatively trivial.

here is my code

$list[] = array(
    'title' => 'Laundry',
    'priority' => 2,
    'due' => '06/09/2016',
    'day' => 0,
    'repeat' => true,
    'complete' => false,
);
$list[] = array(
    'title' => 'Dishes',
    'priority' => 2,
    'due' => null,
    'day' => 0,
    'repeat' => true,
    'complete' => false,
);
$list[] = array(
    'title' => 'Dust',
    'priority' => 3,
    'due' => null,
    'day' => 5,
    'repeat' => true,
    'complete' => false,
);




$newArray = array ('one' => '1', 'two' => '2', 'three' => '3');

foreach ($newArray as $key => $value) {
    echo $key . " = " . $value . "\n";
}

foreach ($list as $key => $item) {
    echo $key . '=' . $item;
}

The first hash works as expected, but I am getting a string conversion error looping through the $list hash, when Im expecting the same result. $list[] is an example of the multidimensional array Im working with.

Thanks for help, Chris

$item is an array. For example, this is $item when the loop runs for the first time:

Array ( [title] => Laundry [priority] => 2 [due] => 06/09/2016 [day] => 0 [repeat] => 1 [complete] => )

To use the echo function, you need a string, which is why you get an error because $item is not a string but an array.
