Count duplicate numbers inside of foreach - php

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
)

Not sure why you use number_format(), but I'm guessing you need something like this
$num_array = []; // Initialize number array
foreach ($parsed_json1->numbers as $item) {
$ui = $item->no;
$currentp= number_format($ui, 6);
$num_array[] = $currentp; // Store each number first to number array
}
// After foreach loop, do array_count_values to number array
$vals = array_count_values($num_array);
print_r($vals); //Print result
