Question

I have a nested associative array like this:

$inputTypes= array( 
    "natural" => array(
        "text",
        "password",
        "textarea",
        "radio",
        "checkbox",
        "file"
    ),
    "hybrid" => array(
        "image",
        "date" ,
        "url",
        "email"
    )
);

I want to print its key names, applying code shown below:

foreach ($inputTypes as $inputs){
    echo key($inputTypes).'<br>';
}

but i get this output

hybrid
hybrid
