Optimized Logic to find high score - php

Question

Basically this is related to a squash application where we have 2 scores. One is from winner point of view and another from loser point of view.
eg.
Score1: 11-5,11-5,11-5 (Winner point of view)
Score2: 5-11, 5-11,5-11 (Loser point of view)
Now in my logic i want to find which is the winner score and which is the loser score.
I have written my logic in the below way and it does work. But i want to know if their is any other better/optimized way of writing this.
$high1 = 0;
$high2 = 0;
$score1 = "2-11,5-11,4-11,4-4";
$score2 = "11-2,11-5,11-4,4-4";
$score1Array = explode(",",$score1);
$size = sizeof($score1Array);
for($i = 0; $i < $size; $i++) {
$checkscore1 = explode("-",$score1Array[$i]);
if($checkscore1[0] < $checkscore1[1]) {
$high1++;
}else if($checkscore1[0] > $checkscore1[1]) {
$high2++;
}
}
if($high1 > $high2) {
$winningScore = $score2;
$losingScore = $score1;
}else{
$winningScore = $score1;
$losingScore = $score2;
}
echo $winningscore;
echo $losingscore;

Answer 1

What about something like this:
function is_winning($score) {
$split_scores = preg_split('/(-|,)/', $score);
$wins = $losses = 0;
for($i = 0; $i < count($split_scores) / 2; $i += 2) {
if($split_scores[$i] > $split_scores[$i + 1])
$wins++;
if($split_scores[$i] < $split_scores[$i + 1])
$losses++;
}
return $wins > $losses;
}
Assuming $score is formatted as in your question. You can then use it like this:
$score1 = "2-11,5-11,4-11,4-4";
$score2 = "11-2,11-5,11-4,4-4";
if(is_winning($score1)) {
$winning_score = $score1;
$losing_score = $score2;
} else {
$winning_score = $score2;
$losing_score = $score1;
}
echo $winning_score;
echo $losing_score;
The idea is to split the score into an array where the even numbered indexes have the left score and the odd numbered indexes the right score. We then count the number of wins and the number of losses. If there's more wins then losses then we return true since the score was a winning score. If there's not more wins then losses we simply return false.

Answer 2

This should work
$score1 = "2-11,5-11,4-11,4-4";
$score2 = "11-2,11-5,11-4,4-4";
$l = $r = 0;
$score1_sets_arr = explode(',', $score1);
foreach ($score1_sets_arr as $set_score) {
$set_score_arr = explode('-', $set_score);
if ($set_score_arr[0] > $set_score_arr[1]) {
$l++;
} else {
$r++;
}
}
if ($l > $r) {
$winning_score = $score1;
$losing_score = $score2;
} else {
$winning_score = $score2;
$losing_score = $score1;
}

Answer 3

you can use this :
<?php
$high1 = 0;
$high2 = 0;
$score1 = "2-11,5-11,4-11,4-4";
$score2 = "11-2,11-5,11-4,4-4";
$explode = explode(",",$score1);
for($i=0;$i< sizeof($explode);$i++){
$explode2= explode("-", $explode[$i]);
if($explode2[0] <= $explode2[1]){
echo $explode2[0]."-";
echo $explode2[1]." ";
}
}
echo "<br />";
for($i=0;$i< sizeof($explode);$i++){
$explode2= explode("-", $explode[$i]);
if($explode2[1] >= $explode2[0]){
echo $explode2[1]."-";
echo $explode2[0]." ";
}
}
?>

Answer 4

for Winner point of view, all big score in left,otherwise in right. so u can just detect the first score.
$score1Array = explode(",",$score1);
$checkscore1 = explode("-",$score1Array[$i]);
if($checkscore1[0] < $checkscore1[1]) {
echo $score2;
echo $score1;
}else{
echo $score1;
echo $score2;
}
Fix: above code is wrong,try this:
$score1value = eval(str_replace(",","+",$score1));
$score2value = eval(str_replace(",","+",$score2));
if($score1value < $score2value) {
echo $score2;
echo $score1;
}else{
echo $score1;
echo $score2;
}
