I have an array in which I have stored a sorted set of dates, for example:

2000-12-27
2000-12-28
2000-12-28
2000-12-30
2000-12-30
2001-01-01
2001-01-01
2001-01-03
... etc

I want to build an array that hold the number of times each date occurs, fir example

2000-12-27,1
2000-12-28,2
2000-12-30,1
2001-01-01,2
2001,01-03,1

I tired using $newarray=array_count_values($myarray);

but I get the error "Warning: Can only count STRING and INTEGER values!"

So, is there a way to easily count the occurance of these dates?

Thanks for any help,
Basil

    It's probably possible with the various array functions, but here's another way.

    foreach($arr as $a)
{
  ++$newarr[$a];
}

      I may try that, but I'd like to use a PhP function like:
      $newarray = array_count_values($myarray);

      I have learned that I can not use this function with multi-dimensional arrays, so I have made "$myarray" a single dimension array with sorted dates. My question now is, how do I access individual items in the new array?

      When I do this:
      $newarray = array_count_values($myarray);
      print_r($newarray);

      this will print out all the items like this:
      Array ( [2000-12-27] => 1 [2000-12-28] => 5 [2000-12-29] => 2 [2000-12-30] => 2 [2000-12-31] => 2 [2001-01-01] => 1 [2001-01-02] => 3 ....etc.

      But when I try something like:
      echo $newarray[0][0]; to try and echo the first element, I get nothing? I;m sure its something simple, but can someone tell me, if I have user array_count_values($myarray); to make a new array that contains the occurance of each date, how do I access the data elements inside the new array?
