Question

I have the following array:

I want to sort

Answer 1

simple use array_count_values and array_fill and array_merge

1st : array_count_values will get the values presented count as a array like below .

Array ( [raj] => 3 [ganesh] => 2 [rahul] => 2 [mayur] => 1 )

2nd : Apply arsort() . descending order, according to the value

3rd : Loop that array and make the new array based on count fill the array using array_fill .

4th : Then merge the array .

$val){

   $value= array_merge($value,array_fill(0,$val,$key));
}

print_r($value);
