dd($request->all()) will display contents of the array.

If you want to see the title, do this:

dd($request->title);

try to use:

echo count($arr); dd($arr);

or

echo count($arr); print_r($arr); die;

You do not say that you need to count them in your questions but here you go:

The aray:

  $arrayname= array(
            array('a', 'b', 'c'),
            array('r', 't','y', 'u'),
        );

The function

    for ($i=0;  $i < count($arrayname); $i++){
        $singlearray[$i]= count($arrayname[$i]);
    }

Result

array:2 [▼
  0 => 3
  1 => 4
]

$a = $request->all();
$flatArray = [];
$it = new RecursiveIteratorIterator(new RecursiveArrayIterator($a));
foreach($it as $v) {
  $array[] = $v;
}
dd(count($flatArray));
