PHP / MySQL查询帮助

Question

我有这样的查询：

$query = "SELECT gyms.name FROM `fighters_team` INNER JOIN gyms ON gyms.id = fighters_team.gym_id WHERE fighter_id = $fighter_id";
    if ($result = $mysqli->query($query)) {
        while($row = $result->fetch_assoc()) {
            echo $row['name'];
            echo " / ";
        }
    }

最重要的是：“团队1 /团队2 /”

我想要做的是摆脱最后一项的尾部斜线。 所以如果有两个项目，它应该只说“Team 1 / Team 2”。

有谁知道我怎么能接近这个？

谢谢！

Answer 1

$query = "SELECT gyms.name FROM `fighters_team` INNER JOIN gyms ON gyms.id = fighters_team.gym_id WHERE fighter_id = $fighter_id";
    $names = array();
    if ($result = $mysqli->query($query)) {
        while($row = $result->fetch_assoc()) {
            array_push($names, $row['name']);
        }
        echo implode(' / ', $names);
    }

我希望这会奏效。

Answer 2

尝试：

$query = "SELECT gyms.name FROM `fighters_team` INNER JOIN gyms ON gyms.id = fighters_team.gym_id WHERE fighter_id = $fighter_id";
    if ($result = $mysqli->query($query)) {
        while($row = $result->fetch_assoc()) {
            $teams .= $row['name'].' / '.'';
            echo rtrim($teams,'/ ');
        }
    }

那是你在找什么？
