PHP MySQLi numrow输出1，即使该值大于或小于1

Question

I have this PHP script, which outputs the variable inside the lr column:

$conx = mysqli_connect("value here", "value here", "value here", "value here");
$sql = "SELECT lr FROM locations";

if (mysqli_connect_errno($conx)){
    die("Failed to connect to MySQL: " . mysqli_connect_error());
    }
        $query = mysqli_query($conx, $sql);
        $numrows = mysqli_num_rows($query);
        if ($numrows > 1) {
            echo "No locations found";
        } elseif ($numrows == '1') {
            echo "1 location found";
        } elseif ($numrows > 0) {
            echo $numrows." locations found";
        }
        // Free result set
        mysqli_free_result($query);

mysqli_close($conx);

Everything seems to work fine, but when it outputs the result it always outputs 1 even if the value is higher or lower than 1

Anyone with a solution?

Try this, see if it suits your goal: (this is a very basic example)

$conx = mysqli_connect("value here", "value here", "value here", "value here");
$sql = "SELECT lr FROM locations";

if (mysqli_connect_errno($conx)){
    die("Failed to connect to MySQL: " . mysqli_connect_error());
    }
$query = mysqli_query($conx, $sql);
    while($row=mysqli_fetch_array($query);)
        {
            echo $row['lr']." ";
        }

mysqli_close($conx);
