使用$ mysqli-> insert_id分配主题以发布在论坛脚本中是否安全? [英] It is safe to use $mysqli->insert_id for assign topic to post in a forum script?
问题描述
我有一个论坛脚本,该脚本为每个新主题创建一个容器",并将与该主题链接的每个帖子分配给该主题.
I've a forum script that makes for every new topic a "container" and assign to it each post linked to the topic.
因此,当我打开一个新主题时,我的脚本会在forum_topics
中创建一个新行,并在forum_posts
中创建一个新行.
So, when I open a new topic my script makes a new row in forum_topics
and a new row in forum_posts
.
在forum_posts
中,将主题容器的id
放入parent
列.
要知道谁是我正在创建的帖子的容器,我使用:
For know who is the container of the post I'm creating I use:
$mysqli->insert_id
我想知道它是否安全,我认为对于同时打开一个新主题的两个用户...这是一个合理的问题吗?
I'd like to know if it is safe, I think to two users who open a new topic at the same time... It is a plausible problem?
推荐答案
是的,它很安全.
每个PHP进程使用单独的连接,并且此变量包含此连接中插入的ID
Yes it is safe.
Each PHP process uses separate connection and this variable contains inserted id from this very connection
