• PHP foreach loop key value 4 answers

In my PHP code I want to check inside foreach iteration what is the current array key (In code below: key1/key2/key3/key4/key5).

I have assoc array which looks like this:

var_dump($myArray);

array(5) {

    ["key1"]=> array(2) {....}

    ["key2"]=> array(2) {....}

    ["key3"]=> array(2) {....}

    ["key4"]=> array(2) {....}

    ["key5"]=> array(2) {....}

}

foreach($myArray as $key) {
    echo key($myArray);
}

For example this only returns: key1key1key1key1key1

My desired output should look like: key1key2key3key4key5

I've been searching for a while but I can't find any smart solution.

Thank you :)
