counting items in an array

I have the array 

Array ( [0] => Array ( [field_yourrating_rating] => 100 ) [1] => Array ( [field_yourrating_rating] => 80 ) [2] => Array ( [field_yourrating_rating] => 100 ) )

I want to be able to count the number of occurences of each value - for exmaple, 100 appears 1 time, and 80 appears one time.

I tried using array_count_values but it doesn't seem to work with a multidimensional array! What else can I try?

If the array is only ever structured as it is in your example then this will work:

  foreach ($array as $value)
  {
    $count[current($value)] += 1;
  }

And then $count will be an array where the keys are the values of the input array and the values are the number of times they occur.

use the following function...

function array_searchRecursive($needle, $haystack, $strict = false, $path = array())
{
        if (!is_array($haystack))
        {
                return false;
        }
        foreach ($haystack as $key => $val)
        {
                if (is_array($val) && $subPath = array_searchRecursive($needle, $val, $strict, $path))
                {
                        $path = array_merge($path, array($key), $subPath);
                        return $path;
                } elseif ((!$strict && $val == $needle) || ($strict && $val === $needle))
                {
                        $path[] = $key;
                        return $path;
                }
        }
        return false;
}

and a simple

echo sizeof(array_searchRecursive(see arguments above));

would give you the answer ;)

have a nice day!
