Getting error Cannot use a scalar value as an array

I want to generate random numbers between 0 and 1, and push them to two dimension array. And i'm getting this error:

Cannot use a scalar value as an array

This is my code:

<?php 

    $zero = $one = $rand = 0;
    $arr = array(array());

    for($i = 0; $i < 5; $i++) {
            $arr[$i] = $rand;

        for($j = 0; $j < 10; $j++) {
            $rand = mt_rand(0,1);
            if ($rand == 0) {
                $one++;
            } else {
                $zero++;
            }
            $arr[$i][$j] = $rand;
            echo $arr[$i][$j];
        }
            echo "<br/>";
    }
?>

$arr[$i] is a scalar value as you are assigning it an integer here:

$arr[$i] = $rand;

There for it is not an array. But you are trying to access it like an array which throws this error:

$arr[$i][$j] = $rand;

You either need to make that value an array or use a different variable for holding your array data. But you can't do both at once.
