Mode calculator
Calculates and returns the mode of the numbers given
<?php
function mode($numbers=array())
{
if (!is_array($numbers))
$numbers = func_get_args();
$amt = array_count_values($numbers);
sort($amt);
foreach ($amt as $key => $val)
if ($val == max($amt)) return $key;
}
/*
echo mode(array(2,2,3,3,4,5)); // 2
echo mode(4,4,3,3,3,2,4,5); // 4
*/
?>
Usage
As seen in the commented portion of code, this function can take either an array of numbers, or multiple parameters of numbers. *note* returns the "first" key that is a mode, only one is returned regardless of uniqueness.
