How do I get the last inserted ID of a MySQL table in PHP?

Question

I have a table into which new data is frequently inserted. I need to get the very last ID of the table. How can I do this?

Is it similar to SELECT MAX(id) FROM

It's ok to use mysql_insert_id(), but there is one specific note about using it, you must call it after executed INSERT query, means in the same script session. If you use it otherwise it wouldn't work correctly.
