Answer 1

Use mysqli_insert_id(), which returns the auto-generated id used in the last query.

Read “PHP mysql_insert_id() Function” or “mysql_insert_id“.

Example:

<?php
$query= "INSERT INTO table_name VALUES ('a','b','c')";
$result = mysql_query($query);
echo "INSERT statement ID is" . mysql_insert_id();
?>

And do read the big red box in the PHP documentation on the mysql_insert_id page, starting with mysqli.

See the PHP Documentation For further reference.
