Question

This a bit looks complicated, i want to get the id column value of the processed query.

example:

$qu = mysql_query("INSERT INTO msgs (msg,stamp) VALUES('$v1','$v2')");  

i want to get the ID of this query after storing the infos in database.

if it’s impossible, is getting the last ID record and adding 1 will be safe and guaranteed?

Note: i use PHP and mySQL

Thanks

If you are using standard mysql in PHP, all you have to do, is to use mysql_insert_id() which takes resource $link as parameter (your mysql connection)

http://php.net/manual/en/function.mysql-insert-id.php

Basic usage:

<?php
    $link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
    if (!$link) {
        die('Could not connect: ' . mysql_error());
    }
    mysql_select_db('mydb');

    mysql_query("INSERT INTO mytable (product) values ('some product')");

    echo 'Last inserted record has id of ' . mysql_insert_id();
?>
