Question

I have a PHP array and I have dumped it below using Zend_Debug:

    $ids = array(13) {
  [0] => string(1) "7"
  [1] => string(1) "8"
  [2] => string(1) "2"
  [3] => string(1) "7"
  [4] => string(1) "8"
  [5] => string(1) "4"
  [6] => string(1) "7"
  [7] => string(1) "3"
  [8] => string(1) "7"
  [9] => string(1) "8"
  [10] => string(1) "3"
  [11] => string(1) "7"
  [12] => string(1) "4"
}

I am trying to get how many times each number occurs in the array and output it into an array.

I have tried using array_count_values($ids) but it outputs in the order of most occurred but I cant get the Total times the numbers occur. It gives me the below output:

    array(5) {
  [7] => int(5)
  [8] => int(3)
  [2] => int(1)
  [4] => int(2)
  [3] => int(2)
}

I can see from the above array 7 occurs 5 times but I can access it when I loop through the array!

Any thoughts?

Cheers

You can access the data you want like this:

$ids = array( ...);

$array = array_count_values( $ids);
foreach( $array as $number => $times_number_occurred) {
    echo $number . ' occurred ' . $times_number_occurred . ' times!';
}

Output:

7 occurred 5 times!
8 occurred 3 times!
2 occurred 1 times!
4 occurred 2 times!
3 occurred 2 times!
