MySQLi why am I only getting 1 result? - php

Question

There are three "BC" in the result_category but I am only getting 1 result. This is for a personality quiz. Please Help. I also tried $query = "SELECT result FROM quiz_map where result_category = 'BC'"; but still, only 1 result is showing.
$result = mysqli_query($link, $query);
$cat_a = $cat_b = $cat_c = $cat_d = $cat_e = 0;
while($row = mysqli_fetch_array($result, MYSQLI_BOTH)) {
$cat = $row['category'];
if ($cat == "A") {
$cat_a += 1;
} elseif ($cat == "B") {
$cat_b += 1;
} elseif ($cat == "C") {
$cat_c += 1;
} elseif ($cat == "D") {
$cat_d += 1;
} elseif ($cat == "E") {
$cat_e += 1;
}
}
$array = array('A' => $cat_a, 'B' => $cat_b, 'C' => $cat_c, 'D' => $cat_d, 'E' => $cat_e);
$str = '';
foreach ($array as $i => $value) {
if ($value >= 6) {
$str = $i;
break;
} elseif ($value >= 2) {
$str .= $i;
}
}
$var = sort($array);
$query = "SELECT result FROM quiz_map where result_category = '$str' LIMIT 1";
$result = mysqli_query($link, $query);
$row = mysqli_fetch_array($result);
echo $row[0];
?>

There's many things wrong with your code!
As pointed by #IsThisJavascript and #Cashbee:
You are executing a query with a LIMIT 1 statement, it will only return one record.
As pointed by myself:
Doing echo $row[0] will have the same result, if you are only echoing the first value of the array you can't expect to have multiples can you?
As pointed by #IsThisJavascript:
You need to loop the results array, like so:
while($row = mysqli_fetch_array($result)){
echo $row['result_category'];
}
Consider switching the query from a '=' to a '%like%' statement, to maximize results if you want to get the values that partionaly cointain the string.
