PHP/MySQL查詢幫助

Question

我有這樣的查詢：

$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 "/"; 
     } 
    } 

了就是來了：「團隊1 /團隊2 /」

我想要做的就是擺脫尾隨的在最後一項上削減。所以如果有兩個項目，就應該說「Team 1/Team 2」。

有沒有人有任何想法我可以接近？

謝謝！

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); 
    } 

我希望這會奏效。

Answer 2

嘗試：

$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,'/ '); 
     } 
    } 

是你在找什麼？
