Question

Lets say I have a simple 1D array with 10-20 entries. Some will be duplicate, How would I find out which entry is used the most? like..

$code = Array("test" , "cat" , "test" , "this", "that", "then");

How would I show “test” as the most used entry?

Answer 1

$code = Array("test" , "cat" , "test" , "this", "that", "then");

function array_most_common($input) { 
  $counted = array_count_values($input); 
  arsort($counted); 
  return(key($counted));     
}

echo '<pre>';
print_r(array_most_common($code));
