 Hi,

  This seems like a pretty simple problem, but I can't seem to be able to 
 figure it out. I have a lot of elements in an array, and some of them are 
 duplicates, but I don't want to delete them because I have other purposes for 
 it. Is it possible for me to find out the number of certain elements in an 
 array?

  For example,

   // Create a simple array.
   $array = array(1, 2, 3, 4, 5, 3,3,4,2);
   $total = count($array);
   echo $total;

  If I run the code, the value of $total would be 9. However, what I really 
 want to do is to get the values of the different instances of each, like:

   1 = 1
   2 = 2
   3 = 3
   4=  2
   5=  1

 Is there a simple code that I use to find this out?

 Thanks for your help.

 Alice

Hi,

Try the function array_count_values.
