I need help please again

I have a friend who made a registration system that can send an email with the registered data to the administrator and to the user,

His question is:

How can I read the ID number of the new user registered in my database, that have auto increase function, and display it in the email that the system will send?

$checkid = mysql_query("SELECT id FROM form1 WHERE id='$id'");

$message2 = "Your ID: $id"


?

thanks in advance

 

You needs to get last inserted report if so try this one

If you ask that you want to take current registered user you have to use sessions

 

$checkid = mysql_query("SELECT id FROM form1 WHERE id='$id'");
$id = mysql_insert_id();
$message2 = "Your ID: $id"

PHP:

It's as easy as that.
