                  问题描述

                  我有这个 PHP SQL 语句:

                  I have this PHP SQL statement:

                  $updateCategory = "UPDATE category 
                                     SET name=".$name.", description=".$description.",
                                         parent=".$parent.", active=".$active." 
                                     WHERE id=".$catID."";
                  

                  最好的写法是什么?

                  谢谢,

                  克里斯.

                  推荐答案

                  我建议你使用prepared statements而不是将查询字符串连接在一起:

                  I suggest you use prepared statements instead of concatenating the query string together:

                  $sql = 'UPDATE 
                             category
                          SET
                             name=:name,
                             description=:description,
                             parent=:parent, 
                             active=:active
                          WHERE
                             id=:catID';
                  

                  如果您使用的是 PDO,我强烈建议您这样做:p>

                  if you are using PDO, which I strongly suggest, you would then call it like this:

                  $params = array(
                      ':name'        => $name,
                      ':description' => $description,
                      ':parent'      => $parent,
                      ':active'      => $active,
                      ':catID'       => $catID
                  );
                  
                  $stmt = $pdo->prepare($sql);
                  $stmt->execute($params);
                  

                  您可能会问,为什么要这么麻烦?"这种方法的优势非常明显:

                  You might ask, "why all this hassle?" The advantages of this approach are quite overwhelming:

                  • 您不必关心 SQL 注入,因为数据库驱动程序现在可以处理输入参数的正确转换
                  • 您不必关心转义特殊字符,但您可以专注于您想要实现的目标,而不是如何实现它:-)
