I have this table in MySql db:
After running this query:
SELECT score, count(*) FROM Coaches group by score ORDER BY score DESC
The result table look like this:
Now in php I try to fetch the result and iterate through the array to determine which group each coach belongs to and get his place in the ranking. Therefore I wrote this:
$groupsOfScoresQuery = "SELECT score, count(*) FROM Coaches group by score ORDER BY score DESC";
$result = mysqli_query($dbc, $groupsOfScoresQuery);
if ($result) { // query did successfully run
$response['topCoaches'] = array();
if (mysqli_num_rows($result) > 0) {
while ( $rowScore = mysqli_fetch_array($result, MYSQLI_ASSOC) ) {
$currentRanking++;
$score = array(); // temp user array for one group of scores
$numberOfCoaches; // Number of coaches with this particular number of scores
$scoresGroup; // Scores in the particular group
$score["scores"] = $rowScore["score"];
$score["count"] = $rowScore["count(*)"];
$numberOfCoaches = $score["count"];
$scoresGroup = $score["scores"];
$response["scoresGroup"] = $scoresGroup; // HERE IS THE PROBLEM
.
.
.
more processing
} // end WHILE
Why $response["scoresGroup"] will always conatins the last value from the result? In this case this is 123. I thought that this is the first iteration through the loop and $response["scoresGroup"] wll hold first element (474), during the second iteration should hold 382 ? What I'm doing wrong here? Do I use correct function to fetch result? or should I use different loop to acheive my goal? Thanks for the help in advance.
