i have script puts bunch of variables (in case random letters through d) array, counts frequency of these variables, finds highest frequency , finds key matches frequency. $answerlist = array($a1, $a2, $a3, $a4,); $count = array_count_values($answerlist); $high_value = max($count); $high_key = array_search($high_value, $count); print_r ($high_key); however in case there 2 equal highest values, array_search returns first key. there way return both? this should it: $high_keys = array_keys($count, $high_value); from array_search docs : if needle found in haystack more once, first matching key returned. return keys matching values, use array_keys() optional search_value parameter instead.
