计算foreach中的重复数字

Question

Basically, I am fetching data from an API and that API has duplicate numbers. I want to count the duplicate numbers within the foreach, but its not working for some reason. I am not sure what I am doing wrong. You can see there is 33 many times. See the picture how it prints. It should be showing something like this

Array
(
    [33] => 5
    [2] => 3
)

Code:

foreach ($parsed_json1->numbers as $item) {
    $ui = $item->no;
    $currentp= number_format($ui, 6);
    //echo $currentp;
    //echo "</br>";

    $array = array($currentp);
    $vals = array_count_values($array);
   //echo 'No. of NON Duplicate Items: '.count($vals).'<br><br>';
    print_r($vals);
}

The fundamental flaw of your code is that you take one value and format it, then you put it into array and then do array_count_values on it.

See the difference:

$arr = [33, 32, 23, 33, 22, 23, 32, 33, 33];

print_r(array_count_values($arr));

foreach($arr as $a) {
    $currentp= number_format($a, 6);
    $array = array($currentp);
    $vals = array_count_values($array);
    print_r($vals);

}

First print_r prints:

Array
(
    [33] => 4
    [32] => 2
    [23] => 2
    [22] => 1
)

And the print_r inside foreach prints:

Array([33.000000] => 1)
Array([32.000000] => 1)
Array([23.000000] => 1)
Array([33.000000] => 1)
Array([22.000000] => 1)
Array([23.000000] => 1)
Array([32.000000] => 1)
Array([33.000000] => 1)
Array([33.000000] => 1)

Do you realize the difference?

I guess, what you need is

$arr = (array_count_values([33, 32, 23, 33, 22, 23, 32, 33, 33]));
$new_arr = [];

foreach($arr as $k => $a) {
    $new_arr[number_format($k, 6)] = $a;
}

print_r($new_arr);

Which outputs:

Array
(
    [33.000000] => 4
    [32.000000] => 2
    [23.000000] => 2
    [22.000000] => 1
)
