Php 用于匹配全文搜索的PDO绑定值

嗨，我是PHP PDO的新手，我有一个使用PDO的全文搜索查询

这样绑定值是否正确，我将+和*放在

bindValue（）的内部

会变成这样：

SELECT * FROM DB WHERE MATCH (email, name, live) 
AGAINST ('+searchword1 +searchword2*' IN BOOLEAN MODE)

SELECT * FROM DB WHERE MATCH (email, name, live) 
AGAINST ('+searchword1 +searchword2*' IN BOOLEAN MODE)

SELECT * FROM DB WHERE MATCH (email, name, live) 
AGAINST (:search IN BOOLEAN MODE)

$value = '+searchword1 +searchword2*';

$SQL = $db->prepare($query);                          
$SQL->bindValue(':search', $value, PDO::PARAM_STR);
