我读过多个关于如何编写这些查询的示例，但我很难在使用bindParam时运行这个特定的like
这是匹配以a开头的用户名的正确方法吗？
$term = "a";
$term = "'$term%'";
$sql = "SELECT username
FROM `user`
WHERE username LIKE :term
LIMIT 10";
$core = Connect::getInstance();
$stmt = $core->dbh->prepare($sql);
$stmt->bindParam(':term', $term, PDO::PARAM_STR);
$stmt->execute();
$data = $stmt->fetchAll();
