How to find the foreach index?

Question

Is it possible to find the `foreach` index? in a `for` loop as follows: for ($i = 0; $i < 10; ++$i) { echo $i . ' '; } `$i` will give you the index. Do I have to use the `for` loop or is there some way to get the index in the `foreach` loop?

Answer 1

Yes, you can know the array keys by doing a foreach loop like this:

$my_array = ['a' => 1, 'b' => 2];

foreach ($my_array as $key => $value) {

echo "Array key is " . $key . "\n";

}

This will work with numeric array keys as well.
