Array looping - cannot get key to print

I have an array as follows in $newarray

Array
(
    [111] => Array
        (
            [123] => 0
            [124] => 0
            [125] => 0
            [126] => 0
            [127] => 0
            [128] => 0
            [129] => 0
            [130] => 1
            [131] => 1
            [132] => 1
            [133] => 1
            [134] => 1
            [135] => 1
        )

    [222] => Array
        (
            [123] => 0
            [124] => 0
            [125] => 0
            [126] => 1
            [127] => 1
            [128] => 1
            [129] => 1
            [130] => 1
            [131] => 1
            [132] => 1
            [133] => 1
            [134] => 1
            [135] => 1
        )

    [333] => Array
        (
            [256] => 0
            [321] => 0
            [456] => 0
            [489] => 0
            [652] => 1
            [741] => 1
            [965] => 0
        )

)

I need to grab the key names (111, 222 and 333 in this case) in a foreach:

The following always spits out "222" 3 times, regardless of what I do. Anything obvious?

foreach($newarray as $value) {
echo key($newarray) . "<br />";
}

Output

222
222
222

This is the correct way to use foreach

foreach($newarray as $key=>$value) {
    echo $key . "<br />";
}

or you can use

print_r(array_keys($newarray));

try this:

foreach($newarray as $key => $value)
{
     echo $key . "<br />";
}
