PHP-Arrays-Get the occurance of each value in numeric array

Like as always we have a problem we have some prerequisites we will have a function and we will draw some results


Problem and Prerequisites :

We have an array let us suppose array(1,2,1,3,4,5,4,6,3,2,1,2,8,9,3,4,5,3,2,4,6,2) and we want to create a function that checks for number of times value repeats in the array.

So we need and output like

1 repeats 3 times
2 repeats 5 times etc.

Function and Solution :

 <?php
 function get_modes($numarray)  
 {  
   if(!(is_array($numarray)))  
     throw new Exception ('Parameter Not an array');  
   $revarray=array();  
   foreach($numarray as $key=>$value)  
   {  
     if(array_key_exists($value,$revarray))  
     {  
       $revarray[$value]++;  
     }  
     else   
     {  
       $revarray[$value]=1;  
     }  
   }  
   return $revarray;  
 }  
 $myarray=array(1,2,1,3,4,5,4,6,3,2,1,2,8,9,3,4,5,3,2,4,6,2);  
 $navarray=get_modes($myarray);  
 foreach($navarray as $key=>$value)  
 {  
   echo $key." repeats ".$value." times<br/>";  
 }  
 ?>  

Output:

1 repeats 3 times
2 repeats 5 times
3 repeats 4 times
4 repeats 4 times
5 repeats 2 times
6 repeats 2 times
8 repeats 1 times
9 repeats 1 times
