php - Algorithm to count most repeated element; -

-

i have tree of structure blook->house->room
each room has data , specific status red, blue, green, empty.

i have iterate through tree , and display common color on each level.

is there algorithm similar binarymask assign numeric value each color, , store there "sum" single integer , @ time able extract common color sum?

(if of colors have equal counts priority red > blue > green taken)

use array that... this,

$colors = array('red' => 0, 'blue' => 0, 'green' => 0, 'empty' => 0); //assign values $colors['red'] += 1; //get maximun array_keys($colors, max($colors))
