Show all multidimensional array keys without their values?

Question

I am working with multidimensional arrays and i need dumping they keys. But their values are wery huge. Is there some easy and quick way dump keys like print_r or var_dump but without values? Or truncated values?

Own function or 'helper' i can write by myself i want know whether exist some default function which one knows...

Does this help? http://stackoverflow.com/questions/7994497/how-to-get-an-array-of-specific-key-in-multidimensional-array-without-looping — clearshot66, Mar 31 '17 at 13:36

What about array_walk_recursive?

 array_walk_recursive($mutliDimArray, function($v, $key){       
    echo "<br/> key: ".$key."    val: ".$v;     
 });
