Try this 

var_dump($reads[0]["517a5745e8505"]);

for what you want as per comments do this, put you array in a $arr variable and follow what I am doing.

$firstelementvalues = array();
    $i = 0;
    foreach ($arr as $key=>$val) {

        $x = 0;
        foreach ($val as $value) {
            if ($x == 0) {
                $firstelementvalues[] = $value;
                $x = 1;
            }

        }

        $i++;
    }

print_r($firstelementvalues);

Output is 

    Array
(
    [0] => Ngee Ann Poly_Keywords report
    [1] => Keyword
    [2] => accounting diploma
)

Your reads array has no numeric keys in the second dimension. You could do something like this, if you have no clue about the keys:

$read = $reads[0];
// I am getting all keys now, because I guess you also want to process the rest of that data
$readKeys = array_keys($read);
var_dump($read[ $readKeys[0] ] );

It's because your array doesn't have element [0][0].

If you want to select first element in second dimension array you can use current:

$lev1 = current($yourArray);
$lev2 = current($lev1);

I think that you need to use loop (for,foreach) if you would like to display AND use the data. var_dump is: Arrays and objects are explored recursively with values indented to show structure.

Because there is no value in array with 0 offset so please try like

var_dump($reads[161][0]);
