I'm still a newbie in programming world..
And I just realized that PHP has a function "mysql_insert_id()" to get the most recent id that generated by AUTO INCREMENT.
But, before I use it, I want to know
Is it safe to use it when many users insert data in the same page?
For example, there are many users register to a site at the same time.
Will there any conflict?
Or everything will be alrigth?
Sorry for my English.
